What Are the Key Features to Look for in Drill Bits for Locksmithing?

• Coating: A coating such as titanium or black oxide can enhance the performance of the drill bit. These coatings reduce friction, increase heat resistance, and improve the bit’s lifespan, which is particularly beneficial when working with tough materials.
• Size Variety: Having a range of sizes is essential for locksmiths, as different locks require different drill bit diameters. A comprehensive set allows for greater versatility when addressing various lock types, ensuring that the locksmith can tackle any job effectively.
• Tip Design: The tip of the drill bit should be designed for precision and efficiency. Split tips or pointed tips can help start drilling without wandering, providing accurate holes necessary for lock manipulation.
• Shank Type: The shank of the drill bit should match the drill being used, with common types being straight shanks or tapered shanks. Ensuring compatibility helps maintain stability and control during drilling, which is critical for locksmithing tasks.
• Length: Drill bits come in various lengths, and the length required will depend on the specific lock being drilled. Longer bits may be necessary for deep-set locks, while shorter bits can be used for standard locks, providing flexibility in different situations.
• Flute Design: The design of the flutes on the drill bit affects how debris is removed from the hole. A good flute design facilitates efficient chip removal, reducing the risk of binding and overheating during the drilling process.
