Why Drill a Tubular Lock?
There are several reasons why you might need to drill out a tubular lock. The most common scenarios include:
- Lost Keys: If you’ve lost the unique key for your tubular lock, and picking or other bypass methods aren’t working, drilling becomes a viable option.
- Malfunctioning Lock: Sometimes, the internal mechanism of a tubular lock can fail, making it impossible to open even with the correct key.
- Security Concerns: In situations where a lock is compromised or you need to secure an area quickly, drilling can provide immediate access.
- Emergency Situations: Like any safe cracking scenario or urgent lockout, drilling can be a necessary evil.
It’s important to remember that drilling is a destructive process. It will permanently disable the lock. If you’re unsure or dealing with a high-security application, it’s always best to consult a professional locksmith. They have the specialized locksmith tools and expertise for lock drilling techniques without causing unnecessary damage.
Tools You’ll Need
Before you begin, gather all the necessary tools. Having everything ready will ensure a smoother and safer operation.
Essential Drilling Equipment:
- Power Drill: A variable-speed drill is ideal. It allows for precise control over the drilling speed.
- Drill Bits:
- High-Speed Steel (HSS) Drill Bits: These are essential for cutting through metal.
- Cobalt Drill Bits: For even tougher materials, cobalt bits offer superior durability and heat resistance.
- Assortment of Sizes: You’ll need a range of sizes, starting small and progressively increasing.
- Center Punch: To create a small indentation for the drill bit to start, preventing it from wandering.
- Hammer: To strike the center punch.
- Safety Glasses: Absolutely crucial to protect your eyes from metal shavings and debris.
- Gloves: To protect your hands and improve grip.
- Lock Lubricant: To help the drill bit cut smoothly and reduce friction.
- Cutting Fluid or Oil: Can be used instead of or in conjunction with lubricant to keep the drill bit cool.
- Measuring Tape or Ruler: For precise placement.
- Marker or Pencil: To mark drilling points.
- Vise or Clamps: If you can remove the cylinder, a vise will hold it securely.
- Screwdriver: To remove any retaining screws or plates if applicable.
Specialized Locksmith Tools (Optional but Recommended):
While not strictly necessary for a basic drill-out, some tools can make the process more efficient and less damaging:
- Lock Pick Set: Even if you plan to drill, attempting tubular lock picking first might yield results without destruction.
- Tension Wrench: Used in conjunction with lock picks.
- Magnifying Glass: For examining small internal components and marking precise drilling points.
- Deburring Tool: To clean up rough edges after drilling.
Preparing the Tubular Lock for Drilling
Proper preparation is key to a successful and safe drill-out. Rushing this step can lead to mistakes and potential injury.
Step 1: Assess the Lock and Environment
- Identify the Lock Type: Confirm it’s a tubular lock. These have a round, hollow shaft with the keyhole in the center.
- Check for Security Features: Some high-security tubular locks have hardened steel pins or plates to resist drilling. This might require specialized bits or techniques, often reserved for professional locksmith tools.
- Clear the Area: Ensure you have a stable surface to work on and that there are no flammable materials nearby, especially if using cutting oil.
- Secure the Lock (If Possible): If you can remove the lock cylinder from the door or device, secure it in a vise. This makes drilling much easier and more accurate. If the lock is still installed, you’ll need to be extra careful not to damage the surrounding material.
Step 2: Locate the Shear Line
The “shear line” is the critical point in any pin tumbler lock, including tubular ones. It’s the line where the bottom pins and top pins separate when the correct key is inserted. When drilling at the shear line, you effectively destroy the pins and allow the cylinder to turn.
- Visual Inspection: For many tubular locks, the shear line is located roughly in the center of the cylinder, where the plug meets the housing.
- Marking the Shear Line: Using a marker, lightly mark the suspected shear line around the circumference of the lock cylinder. This line will guide your drilling.
Step 3: Mark the Drilling Point
Once the shear line is identified, you need to decide where to drill. The goal is to drill through the shear line to disable the locking pins.
- Center of the Cylinder: Often, the most effective drilling point is directly into the center of the cylinder, aiming to intersect the shear line.
- Multiple Points: Some techniques involve drilling at multiple points along the shear line to ensure all pins are compromised. This is particularly useful if the exact shear line is difficult to pinpoint.
Step 4: Safety First – Gearing Up
- Wear Safety Glasses: This is non-negotiable. Metal shavings can fly at high speeds.
- Wear Gloves: Protect your hands from sharp edges and potential heat.
- Secure Loose Clothing: Avoid anything that could get caught in the drill.
The Drilling Process: Step-by-Step
This is where you’ll apply your lock drilling techniques. Patience and precision are key.
Step 1: Creating the Pilot Hole
- Use a Center Punch: Place the tip of the center punch directly on your marked drilling point.
- Tap with a Hammer: Gently tap the punch with a hammer to create a small indentation. This prevents the drill bit from “walking” or slipping off the surface.
- Start with a Small Drill Bit: Select a small HSS drill bit (e.g., 1/16 inch or 1.5mm).
- Low Speed, Steady Pressure: Insert the small bit into your drill. Set the drill to a low speed. Apply steady, consistent pressure to drill a pilot hole into the marked spot. Keep the drill perpendicular to the lock cylinder.
- Add Lubricant: Apply a drop of cutting fluid or oil to the drill bit and the drilling area. This helps cool the bit and makes drilling easier.
Step 2: Progressively Enlarging the Hole
- Increase Drill Bit Size Gradually: Once the pilot hole is established, switch to a slightly larger drill bit. Continue this process, increasing the bit size incrementally (e.g., 1/16″, 3/32″, 1/8″, etc.).
- Drill to the Shear Line: As you increase the bit size, aim to reach the shear line. For most tubular locks, the shear line is typically around 1/4 to 3/8 inch (6-10mm) into the cylinder.
- Maintain Perpendicularity: Always keep the drill bit straight and perpendicular to the cylinder. Drilling at an angle can miss the critical pins or damage the lock housing.
- Clear Debris: Periodically withdraw the drill bit to clear out metal shavings. Reapply lubricant as needed.
- Listen and Feel: Pay attention to the sound and feel of the drill. A change in sound might indicate you’ve hit pins or the core.
Step 3: Reaching and Disabling the Pins
The objective is to drill through the shear line, destroying the pins that hold the cylinder in place.
- Drill Through the Core: When you reach the approximate depth of the shear line, you’ll likely feel resistance as the drill bit encounters the pins.
- Focus on the Shear Line: Continue drilling along the marked shear line with bits that are roughly the diameter of the pins themselves, or slightly larger. The goal is to sever the pins.
- Tubular Lock Bypass Considerations: For some more basic tubular locks, drilling just past the shear line might be enough to compromise the mechanism. For more complex or picking hardened locks, you might need to drill multiple holes at intervals along the shear line.
- Test for Movement: After drilling to the expected depth, try to turn the plug with a screwdriver or by hand. If it doesn’t turn, you may need to enlarge the hole slightly or drill at a different point along the shear line.
Step 4: Removing the Cylinder
Once the pins are compromised, the cylinder should be free to turn.
- Use a Flathead Screwdriver: Insert a flathead screwdriver into the drilled-out hole or keyway.
- Apply Turning Pressure: Gently apply turning pressure. If you’ve successfully drilled the shear line, the cylinder should rotate, allowing you to remove it.
- If it Doesn’t Turn: You might need to drill deeper or at a slightly different angle. Reassess your drilling points and continue with a slightly larger bit. Be cautious not to over-drill and damage the lock mechanism’s housing or the surrounding material.
Advanced Techniques and Considerations
While the basic method is straightforward, some situations call for more nuanced approaches.
Drilling High-Security Tubular Locks
High-security locks often incorporate anti-drilling features such as:
- Hardened Steel Inserts: These can be placed in front of the shear line or throughout the cylinder to resist drilling.
- Ball Bearings: Some designs embed ball bearings in the cylinder face to deter drill bits.
For these locks, you might need:
- Cobalt Drill Bits: Significantly harder than HSS, they can chew through hardened steel.
- Diamond-Tipped Bits: For extremely hardened components.
- Multiple Drill Points: Drilling in a circular pattern around the shear line can help defeat hardened inserts.
- Specialized Locksmith Tools: Professionals might use tools designed for safe cracking or picking hardened locks that can overcome these defenses more effectively.
Dealing with Lock Manipulation vs. Drilling
Lock manipulation is a non-destructive technique used by locksmiths to open locks without keys. If you’re not an experienced locksmith, attempting tubular lock picking or manipulation can be difficult and time-consuming, especially if you lack the proper locksmith tools. Drilling is often faster but results in the destruction of the lock.
When to Call a Professional Locksmith
It’s crucial to recognize your limits. You should call a professional locksmith if:
- You are uncomfortable with power tools or the drilling process.
- The lock is part of a high-security system or a valuable item.
- You’ve attempted to drill and haven’t been successful without causing damage.
- You need the lock opened quickly and without risk of further damage.

Frequently Asked Questions (FAQ)
Q1: What is the easiest way to open a tubular lock without a key?
The easiest methods often involve specialized locksmith tools for tubular lock picking or other forms of tubular lock bypass. However, without the right skills and tools, drilling is often considered the most direct, albeit destructive, approach.
Q2: Can I pick a tubular lock with household items?
While some simple tubular locks might be susceptible to makeshift tools, most require specialized picks and tension wrenches for successful tubular lock picking. Using incorrect tools can damage the lock further.
Q3: How deep do I need to drill into a tubular lock?
You need to drill to the shear line, which is typically around 1/4 to 3/8 inch (6-10mm) into the cylinder, depending on the lock’s size. The goal is to sever the pins located at this point.
Q4: What happens if I drill too far into a tubular lock?
Drilling too far can damage the internal mechanism beyond the pins, potentially damaging the lock housing or the surrounding material if the lock is still installed. It can also make it harder to turn the cylinder afterward.
Q5: Is drilling a tubular lock a common practice for locksmiths?
Yes, drilling is a standard technique for locksmiths when other non-destructive methods fail for tubular cylinder removal. They use it judiciously, often as a last resort for tubular lock defeat when keys are lost or the lock is severely damaged. They are also skilled in lock manipulation for non-destructive entry.
Q6: What kind of drill bits are best for drilling metal locks?
High-Speed Steel (HSS) drill bits are generally suitable for drilling metal. For tougher locks or those with hardened components, Cobalt or Titanium-coated HSS bits are recommended.
Q7: How do I know where the shear line is on a tubular lock?
The shear line is generally located in the middle of the cylinder, where the rotating plug meets the stationary housing. Visually, it’s often the dividing line between these two parts. For picking hardened locks or complex mechanisms, locating this precisely is key.
Q8: What’s the difference between drilling a tubular lock and a pin tumbler lock?
The fundamental principle of drilling to the shear line to disable pins is the same for both standard pin tumbler locks and tubular locks. However, the shape of the cylinder and the arrangement of the pins in a tubular lock can sometimes make access to the shear line different. Some tubular lock bypass techniques are specific to their unique design.
Q9: When should I consider lock manipulation instead of drilling?
Lock manipulation should always be considered first if non-destructive entry is desired. It’s also preferred for high-security locks or when preserving the lock is important. However, manipulation requires significant skill and specialized tools, making drilling a more accessible option for many.
Q10: Can drilling a lock be considered safe cracking?
While safe cracking involves advanced drilling techniques to open safes, drilling a single lock is a much simpler operation. Both require precision, safety awareness, and the right tools, but the complexity and stakes are significantly different.
