HSS drill bits specifications

Choosing the right HSS drill bits

Pick the drill bit size to match your screw, rivet or fixing. For rivets, use a bit 0.1–0.2mm bigger than the rivet diameter. For self tapping screws, use a pilot hole slightly smaller than the screw core. Use a slower speed and cutting fluid on steel to make the HSS drill bits last longer.

Fitting tips

Always wear eye protection and gloves when drilling, fixing or cutting. Use the right drill bit for the material, keep tools in good condition and check for hidden cables and pipes before drilling into walls. Store your HSS drill bits in a dry place so it is ready for the next job. For more guidance, see the Health and Safety Executive website.

Care and maintenance

To get the longest life from your HSS drill bits, use a steady speed and firm pressure, and use cutting fluid when drilling steel. Let the bit cool between holes, keep the bits in their case so the edges stay sharp, and replace blunt bits early – a blunt bit overheats and drills poor holes.
