Drill bit for general purpose drilling

The Chicago-Latrobe 57230 is a jobber length drill bit made from high speed steel with a black oxide finish. It is designed for general purpose drilling in metal, wood and plastic. The 118 degree split point reduces walking and starts holes cleanly without a centre punch.

15/32 inch capacity with .4688 decimal equivalent

This bit drills a 15/32 in hole, which is .4688 in decimal form. The jobber length provides standard reach for through holes and moderate depth drilling in sheet metal and bar stock. It is not suited for deep hole drilling or high volume production runs where coolant through tooling is required.

Black oxide finish resists heat buildup

The black oxide surface treatment helps retain lubricant and reduces chip welding during normal hand held or drill press use. With no coolant holes the bit relies on external cutting fluid or air cooling for heat management. Expect typical high speed steel wear rates when drilling abrasive alloys or hardened steels.

Questions about this item

Will the 15/32 in drill bit fit the 1/2 in chuck on my older drill press?

Yes, the 15/32 in shank is smaller than a 1/2 in chuck capacity so it will secure properly in your existing drill press.

How can I confirm the 118 degree split point is cutting correctly after I start drilling?

The split point should self-centre without a centre punch and produce short, curled chips in steel when the 118 degree angle is working as designed.

Does the 57230 come in a protective case or do I need to buy storage separately?

The bit is supplied as a single unit without a case; a drill-bit index or pouch must be purchased separately for organised storage.
