DEWALT Titanium Nitride Coated 21-Piece Set
The DEWALT DW1361 set uses a titanium nitride coating to reduce wear, extending life in metal and wood applications commonly encountered during lock installation or repair. The pilot point design initiates cleanly, helping to prevent bit wander when aligning holes for lock hardware screws. Its shanks are designed to resist slippage, maintaining alignment through repeated drilling sessions.
DEWALT 14-Piece 3-Flats Shank Set
This set features a 135-degree split point, helping to prevent walking when starting a hole for lock hardware. The high-speed steel construction provides reliable performance across plastics, woods, and metals, making it versatile for drilling pockets, screw pilot holes, or mounting plates for locks. The 3-flats shank reduces slippage in power tools and drivers.
EFFICERE 8-Piece Premium 1/2” Set
Designed for heavy-duty use, the EFFICERE set employs M2 high-speed steel with dual coating for lubrication retention and corrosion resistance. The 135-degree split point promotes fast, self-centering starts, reducing wandering when drilling precise countersinks or pilot holes for lock components. The kit’s coating and geometry support efficient drilling through various materials encountered in locksmith tasks.
Makita Impact Gold 14 Pc. Titanium Drill Bits
The Makita B-65399 set features a TiN coating that extends bit life, with a 135-degree split point for faster starts and reduced walking. It’s designed for use with impact drivers, providing improved reliability when drilling into tougher materials or when driving fasteners into lock hardware. This set is a solid pick for frequent lock-related drilling tasks that require consistent bit durability.
KLEIN TOOLS 12-Inch Dual-Lock Extension Kit
While primarily an extension, this Klein Tools set features a 12-inch reach and a quick-release locking mechanism to secure bits during lengthy lock installation tasks. Its impact-rated 1/4-inch hex shank ensures compatibility with drivers and drills, helping maintain control when aligning through tight spaces or deep mounting points often found with door hardware or lock assemblies.
Milwaukee Shockwave 18-Piece Set
The Milwaukee Shockwave set is designed for high-torque applications and features parabolic flutes for efficient chip clearing. Anti-walking geometry, along with 135-degree tips, helps ensure precise starts—an important factor when drilling holes for lock hardware or strike plates.

The 1/4″ hex shank supports quick-change chucks, making it convenient for repeat tasks in locksmith work.
Buying Guide
When choosing drill bits for lock-related work, consider the following:
- Material and coating: Titanium or TiN coatings extend bit life in metal and hardwood common to lock installations; look for high-speed steel (HSS) or cobalt variants for durability.
- Point geometry: Split points (135 degrees) reduce walking and provide cleaner starts, which is important for precise mounting of lock hardware and strike plates.
- Shank and compatibility: Hex shanks and 3-flats shanks improve grip in power tools and reduce slippage, especially with impact drivers. Quick-change compatibility saves time during repetitive tasks.
- Chip clearance: Flute design that clears chips efficiently reduces heat buildup and enhances drilling speed in metal and wood.
- Tool rigidity: For deeper mounting or harder materials, choose bits designed for impact drivers or hammer drills to resist breakage under high torque.
- Set scope: For locksmith tasks, a balanced mix of sizes (small for pilot holes, larger for mounting holes) helps cover common scenarios without carrying excessive sets.
- Usage context: Consider whether the work involves metal strike plates, door hardware, or wood framing; select bits tailored to the material to improve hole quality and longevity.
