15-piece HSS jobber drill set

This Drill America set contains fifteen high-speed steel jobber-length bits with a black and gold oxide finish. The round shank fits standard drill chucks and the 135-degree split point reduces walking on contact. It is suited for general-purpose drilling in metal, wood and plastic by tradespeople and DIY users.

Black and gold oxide finish thermals

The oxide coating helps reduce friction and heat build-up during drilling, which lowers cutting temperatures and extends bit life. Lower heat also means less chance of workpiece discoloration in normal use. No lubrication system is included, so standard cutting fluid practices apply for demanding materials.

Metal case keeps bits organised

The supplied metal case holds all fifteen pieces in labelled slots, protecting the cutting edges from damage and making size identification quick. The case has no additional software or digital features; its only function is physical storage and transport. Buyers who want indexed storage for larger bit collections will need a separate case.

Questions about this item

How do I install the 135-degree split-point bits in my drill chuck without them walking on the workpiece?

Tighten the round shank securely in a three-jaw chuck, centre the bit, and start drilling at low speed; the 135-degree split point self-centres so you do not need a centre punch.

What maintenance will the 15-piece HSS jobber set need after repeated use?

Clean chips from the spiral flutes after each job, apply light machine oil to the black-and-gold oxide finish to prevent rust, and resharpen the 135-degree split points when they dull.

Which limit appears first when drilling deep holes in steel with these jobber-length bits?

Chip evacuation becomes the limiting factor; the spiral flutes can pack with swarf in deep cuts, so retract the bit frequently to clear the 32nd-size increments.
