Metallics HSSBG332E 3/32" HSS BLACK AND GOLD JOBBER DRILL - 135 SPLIT PT- SUPER HEAVY DUTY

A 135 degree split point starts cutting on contact instead of walking across the surface, so you can drill steel, strut, and enclosure sheet metal without center punching first. The flatter 135 degree angle also spreads the cutting load over more of the lip, which is why it holds up better than a standard 118 degree jobber point on harder metal.

It is a metal-drilling bit. High speed steel with a black and gold oxide finish and a split point is the configuration used for steel, stainless, strut, and enclosure sheet metal. It will cut wood and plastic fine, but a brad point or auger does cleaner work in wood.

Jobber length is the standard, longest of the common lengths for a given diameter, which gives you reach into a box or behind an obstruction. A stub or screw machine length bit is shorter and far stiffer, so it wanders less and is less likely to snap at a small diameter like 3/32 inch. If you are drilling in tight quarters or free-hand into hard steel, the shorter bit is the better choice; for general reach work, jobber is what you want.

Yes. At 3/32 inch the shank is round and well under the capacity of any 3/8 inch or 1/2 inch keyless chuck, so it runs in any standard cordless or corded drill. It is not a hex quick-change shank, so it will not snap into an impact driver collet without an adapter chuck.

Order by part number HSSBG332E. That number is specific to the 3/32 inch size in the Metallics black and gold 135 degree split point jobber line, so each diameter in the series carries its own number.

Small diameters want high rpm and light, steady pressure. At 3/32 inch the bit is thin enough that leaning on it is the usual cause of breakage, not heat. Keep it spinning, let the split point do the starting, and back out to clear chips on anything deeper than a few diameters. A touch of cutting oil in steel extends the edge noticeably.
