Drill bit set Irwin IW4046602 — wood bits with centering point 3–10 mm (8 pcs) in case

Irwin IW4046602 wood drill bit set includes eight brad-point bits with centering points, covering sizes 3, 4, 5, 6, 7, 8, 9 and 10 mm. Designed for accurate holemaking in timber and board materials, each bit has a sharp brad point to reduce walking at the start of a cut and spurs that help produce clean, splinter-free entry and exit holes. The set comes in a compact storage case to keep the bits organised and protected when transported or stored.

Advantages

The brad-point geometry provides reliable centring and consistent hole accuracy across the included size range. Sharp cutting spurs minimise tear-out on the workpiece edge, improving finish quality without additional sanding. The set covers common woodworking diameters, reducing the need to change tools between tasks, while the storage case ensures quick access and safe storage.

How to use

Select the appropriate drill bit size for the hole required and secure it in the drill chuck, ensuring a firm grip and correct alignment. Position the brad point on the marked drilling location to allow the centering point to engage and prevent slipping. Start drilling at low speed to establish the hole, then increase speed as appropriate for the material and bit size. Apply steady, even pressure and withdraw the bit occasionally to clear chips when drilling deeper holes.

Usage recommendations

Use appropriate drilling speeds for wood materials and ensure the workpiece is clamped securely. For the cleanest edges in veneered or laminated panels, back up the exit side with scrap wood to reduce tear-out. Inspect bits regularly and replace if cutting edges become dull to maintain hole quality and reduce heat build-up in the drill.
