The 9/64" HSS jobber bit

This Westward drill bit is made from high-speed steel with a black and gold finish. The 135 degree split point helps the bit start on contact and reduces wandering. It is suited for general-purpose drilling in metal, wood and plastic where a fractional-inch size is required.

Fractional sizing and split-point geometry

The 9/64 inch diameter matches legacy hardware and imperial drawings without conversion. The split point centres itself, so a centre punch is often unnecessary, saving a step in repetitive work. The jobber length provides standard reach for through-holes and moderate-depth drilling.

High-speed steel under sustained cutting

High-speed steel retains hardness as the tip temperature rises during extended drilling. The 135 degree point distributes cutting forces over a wider angle, slowing edge wear when holes are drilled in succession. The black and gold surface treatment resists corrosion between uses.

Questions about this item

How quickly does the 135° split point dull when drilling hardened steel all day?

The 135° split point on this high-speed steel bit resists walking and reduces thrust, so it stays sharp longer in tough materials, but exact wear life depends on feed pressure and coolant use.

Does the bit overheat or glow during continuous drilling in stainless?

High-speed steel construction handles heat better than carbon steel, yet prolonged stainless work will still raise temperature; use cutting fluid and peck cycles to keep the bit from discolouring.

What chuck size is needed to grip the 9/64" shank?

The 9/64 in shank fits any standard 3/8 in or 1/2 in drill chuck that closes down to .1406 in, so a common keyless or keyed chuck on a corded or cordless drill will hold it securely.
