Drill Bits and Screwdriver Bits

How to choose drill bits and screwdriver bits?

This collection includes sets of HSS drill bits for metal and wood, with announced TiN or titanium coatings, PH2 and assorted bits, sleeves, and magnetic bit holders. It helps you select the right consumable for the material, screw head, and the power level of your drill or driver.

Four correspondences to follow

• Material to be drilled: Wood, metal, and masonry require different geometries.
• Diameter and length: Choose the hole size and a sufficient effective length without oversizing the accessory. A drill bit that is too long flexes more easily.
• Screw head: Phillips (PH), slotted, and other profiles must exactly match the screw. A poorly fitted bit will damage the screw head and increase the risk of slipping.
• Shank: Hexagonal bits, bit holders, and cylindrical drill bits are not mounted in the same way. Check the chuck, length, and compatibility with the tool.

Complete assortment or specialized reference?

A set of drill bits of various diameters is suitable for general maintenance and various tasks. For series work in metal, opt for a dedicated set, correct speed, and an impeccable cutting edge. Long bits facilitate access to recessed screws; magnetic bit holders improve retention without replacing a well-aligned screw drive. PH2 sets are relevant when this type of screw head dominates the worksite.

Good practice and accessory lifespan

Secure the workpiece, wear safety glasses, and center the drilling before accelerating. Adjust speed and force according to the material; avoid overheating, which dulls the drill bit. Clean chips, allow to cool, and store each accessory dry in its compartment. Discard a bent or cracked drill bit and replace a bit with rounded edges. Coating characteristics do not exempt from proper use.
