The best drill bits for screw heads

When it comes to choosing the best drill bits for screw heads, there are several factors to consider to ensure a successful and efficient drilling experience. The type of drill bit you need depends on various factors, such as the size and material of the screw head, the type of screw drive, and the condition of the screw. Here are some recommendations and guidelines to help you select the most suitable drill bits for your project.

Match the Drill Bit to the Screw Head Size and Material:

  • For standard screws made of softer materials like wood or plastic, a twist drill bit is usually sufficient.
  • For harder materials like stainless steel or hardened steel, opt for more durable and heat-resistant drill bits such as cobalt or titanium drill bits.

Consider the Type of Screw Drive:

  • Phillips (+) and Flathead (-) screw drives are the most common types and typically come with drill bits when purchased.
  • For less common screw drives like T-star or other specialty shapes, ensure you have the appropriate drill bit to achieve a secure fit.

Use a Magnetic Bit Holder:

  • Magnetic bit holders securely hold drill bits in place, preventing slippage during the drilling process.
  • They extend the length of the bit, making it easier to reach tight spaces, and they magnetize the tip to hold metal screws in place.

Choose the Right Drill Bit Size:

  • Selecting a drill bit that matches the size of the screw head is crucial to prevent slippage and damage to the screw head.
  • If the drill bit is too small, it may not grip the screw properly; if it's too large, it may not fit securely.

Create a Pilot Hole:

  • Drilling a pilot hole before driving the screw can make the process easier, especially when dealing with hard materials like stainless steel.
  • Use a smaller drill bit than the one used for driving the screw to create a starting point and reduce the risk of slippage.

Adjust the Drill Speed and Torque:

  • Variable speed settings on your power drill allow you to adjust the drilling speed according to the material you're working with.
  • For driving screws, slower speeds are generally necessary to avoid stripping the screw head.
  • Adjust the torque setting to control the amount of force applied, especially when dealing with small or delicate screws.

Prepare the Workpiece:

  • Ensure that the material you are drilling into is securely clamped or held in place to prevent movement and provide a steady drilling surface.
  • Mark the center of the screw head with a pencil or a center punch to create a clear target for your drill bit.

Wear Appropriate Protective Gear:

  • Always wear safety goggles to protect your eyes from flying debris when drilling.
  • Consider wearing work gloves to protect your hands from potential slips or cuts during the drilling process.

By following these recommendations and guidelines, you can effectively select and use the best drill bits for screw heads, ensuring a successful and safe drilling experience.

How to avoid destroying screw heads

Using a power drill can be an efficient way to drive screws, but it can also lead to stripped screw heads if not done properly. Here are some tips to avoid destroying screw heads:

Choose the Right Screw Type:

  • Opt for Torx-head screws, which have a star-shaped recess that fits tightly with the driver bit, reducing the chances of slippage and screw head stripping.
  • Torx-head screws are premium-quality and often feature self-drilling points, self-setting heads, and corrosion-resistant coatings.

Prepare the Screw and Surface:

  • Drill a pilot hole with a bit slightly thinner than the screw's shank to reduce friction and make driving the screw easier. Ensure the hole is the correct depth; if the screw bottoms out, it can lead to increased resistance, causing the screw head to strip or snap.
  • If attaching another piece to the base material, create a screw body clearance hole to achieve a stronger screw joint.

Select the Correct Driver Bit:

  • Ensure the driver bit is the correct size for the screw head. A Phillips-head screw, for instance, requires a Phillips-head bit, and they come in multiple sizes (#1, #2, or #3). Using the wrong size can lead to stripping.
  • The driver bit should fit snugly into the screw head with no "wobble room."

Use the Appropriate Drill Settings:

  • Adjust the clutch to control the amount of force applied by the drill. Start with the lowest setting and gradually increase it until the screw head stops at the desired depth.
  • Use the speed switch, not the trigger, to regulate speed. Squeeze the trigger firmly and release it immediately to start or stop driving.
  • For driving screws, use the slower speed setting on your drill, which delivers more torque.

Apply Proper Technique:

  • Hold the drill at a 90-degree angle to the screw and ensure the driver bit is firmly seated in the screw head.
  • Apply consistent pressure on the driver to keep the bit in the screw slot. Insufficient pressure can cause the bit to run out of the slot and strip the screw head.
  • Align the driver bit with the screw shank. Incorrect alignment can lead to poor engagement and slippage.
  • Start the drill slowly while pushing hard against the screw.

Maintain Your Tools:

  • Worn or broken driver bits can slip and strip the screw head. Regularly inspect and replace your bits to avoid this issue.
  • If using the correct technique but still experiencing slippage, the bit may be worn and needs replacing.

By following these guidelines, you can effectively drive screws with a power drill while minimizing the risk of destroying screw heads.

Drill speed and torque settings

When using a power drill, it is important to adjust the speed and torque settings to suit the specific task at hand. Most drills have multiple speed settings, with some offering three or more speed options. The speed settings are typically labelled as low, medium, or high, and this determines how fast the drill rotates the bit.

The torque settings, on the other hand, control the amount of force or "muscle" applied by the drill at a given speed. Torque settings are usually indicated by numbers, with higher numbers corresponding to higher torque. Adjusting the torque setting allows you to control the depth of the fastener being driven and prevent overdriving.

When driving screws, it is generally recommended to use a low speed setting and a high torque setting. This combination provides the necessary force to drive the screw without excessive speed that could lead to stripping the screw head or damaging the material. For tasks like drilling or driving fasteners, a medium or high-speed setting may be more appropriate.

It is worth noting that the specific speed and torque settings may vary depending on the type of screw and the material being worked on. For example, when driving screws into drywall, a low torque setting is recommended to avoid driving the screw too deep. Conversely, when working with tough materials like pressure-treated lumber or hardwoods, a higher torque setting can help prevent camout, which is when the bit spins in the head and damages the screw.

Additionally, it is crucial to ensure that the drill is set to the correct mode for the task. Most drills have a forward/reverse control that determines the direction of rotation. Some drills also have a dedicated drill mode, which should be used when drilling holes and not when driving screws, as it can cause a sudden twist and lead to potential injury.

Frequently asked questions

Cordless drills are generally more suitable for driving screws than corded drills due to their variable speed and clutch features, which help prevent stripping of the screw head.

It is important to select the correct size and type of drill bit that matches the screw head. Using a worn or ill-fitting bit can lead to slippage and damage to the screw head.

Torx-head screws, commonly found in automobiles and construction, provide a firm grip and reduce slippage. Their star-shaped design allows for tighter fitment and easier driving, but they tend to be more expensive.

Ensure the drill bit is the correct size and securely attached. Apply steady pressure while driving the screw, and consider using a magnetic bit holder for enhanced grip and easier bit changes.

Always wear appropriate protective gear, such as safety goggles and gloves, to safeguard against flying debris. Secure the workpiece firmly and choose the appropriate drill speed and torque settings to avoid over-tightening or stripping the screw head.
