Brad point drill bit DeWalt DT4507-QZ, right-hand rotation, 1 pc, 27 g, polybag

DeWalt DT4507-QZ brad point drill bit, 7 mm diameter, is designed for precision wood drilling. The single-piece brad point geometry with centering point and peripheral cutting edges ensures clean entry holes and reduced splintering in plywood, softwood and hardwood. Supplied as one piece in a polybag with a hanging hole, this right-hand rotation bit is intended for use with compatible handheld or bench drills where accurate, tear-free wood drilling is required.

Advantages

The chrome-vanadium alloy construction gives good wear resistance and consistent performance on wood-based materials. The brad point and two shoulders provide precise centring and minimise wandering at the start of the cut, while the peripheral cutting edges and flute design evacuate chips efficiently to maintain drilling speed and hole quality. The lightweight, single-bit packaging makes storage and transport simple for carpenters and joiners.

Suitable for

• Drilling clean entry holes in plywood
• Precision holes in softwood for cabinetry and joinery
• Holes in hardwood for furniture making and carpentry

How to use

Install the DeWalt DT4507-QZ into the drill chuck and tighten securely. Position the centring point on the marked drilling location to prevent walking, then apply steady, moderate pressure while drilling at the appropriate speed for the wood type. Allow the flutes to clear chips periodically on deep holes to avoid clogging and overheating. Use clamps or a support backing board when drilling near edges to reduce splintering on exit.

Usage recommendations

For best results, select drill speeds appropriate to material hardness: higher speeds for softwood and lower speeds for hardwood. Wear eye protection and secure the workpiece. Replace the bit if signs of dulling or excessive wear appear to maintain hole quality.
