20-piece HSS drill bit set

This Chicago-Latrobe 45656 set contains twenty high-speed steel jobber-length drill bits. The 135-degree split point reduces walking and starts holes cleanly. Black oxide finish adds corrosion resistance and helps retain lubricant. It suits general-purpose metal, wood and plastic drilling in a workshop or on site.

Capacity and headroom

Twenty bits cover a broad range of common diameters for everyday fastening and clearance holes. High-speed steel handles mild steel, aluminium and non-ferrous metals at normal drill-press or hand-drill speeds. The material loses hardness quickly in stainless steel or hardened alloys, so those applications need cobalt or carbide tooling instead.

Questions about this item

Will the 135-degree point angle reduce walking on the 20 HSS bits when I use them with my older drill press?

Yes, the 135-degree split point is designed to start on contact and minimise walking, so the bits will track accurately even on a drill press with some spindle run-out.

How can I confirm the black-oxide finish on all 20 pieces is intact after unpacking the set?

Inspect each bit under good light; a uniform dark grey-black surface with no bright steel showing confirms the black-oxide coating is complete and ready to resist corrosion.
