Application & Fit

This Westward jobber drill bit is built for general-purpose drilling in metal, wood and plastic where a 1/2 inch fractional size is required. The 130 degree split point reduces walking and starts the hole cleanly without a centre punch.

Who It Suits

Machinists and maintenance technicians who need a right-hand cutting, high-speed steel bit with a steam nitride finish for improved wear resistance will find it matches their tooling requirements. Buyers who require coolant-through capability or a left-hand cutting direction should look at alternative tooling.

Deciding Specification

The 130 degree split point geometry is the single feature that determines whether this bit matches the drilling application, as it governs self-centring behaviour and chip formation in the materials being worked.

Questions about this item

How does the 1/2 inch diameter behave when drilling steel on a standard drill press?

The split point and 130 degree angle center the bit quickly and reduce walking on hard materials.

What does the steam nitride finish actually do during cutting?

It lowers friction and resists heat buildup so the high speed steel edge stays sharp longer.

Will the 5-15/16 inch overall length fit a standard 1/2 inch chuck without an adapter?

Yes, the shank is 1/2 inch diameter so it seats directly in any 1/2 inch capacity drill chuck.
