Precision Drilling With Cobalt Steel
The Westward 1/16 inch cobalt steel drill bit is designed for users who need a durable fractional inch bit for general purpose drilling. Its split point geometry helps reduce walking on contact, allowing the bit to start accurately without a centre punch. The straw bronze finish identifies the cobalt alloy and provides a degree of surface lubricity during cutting. It suits maintenance technicians, metal fabricators and hobbyists working with stainless steel, titanium and other hard alloys.
Jobber Length Fits Standard Chucks
The bit has an overall length of 1 7/8 inches with a 7/8 inch flute length, matching the jobber length standard so it fits directly into any 1/4 inch or 3/8 inch drill chuck without adapters. The shank diameter matches the 1/16 inch cutting diameter, keeping the tool concentric through the full depth of cut. Right hand cutting direction works with every conventional corded or cordless drill motor. No through coolant channel is present, so external lubrication or peck drilling clears chips from deep holes.
143 Degree Point Holds Edge Under Heat
The conventional 143 degree point angle distributes cutting forces across a broad lip, letting the cobalt substrate resist softening when temperatures rise during sustained drilling in tough metals. Cobalt steel retains hardness at higher temperatures than standard high speed steel, so the bit maintains its edge through repeated holes without frequent resharpening. The split point is not self centring on very hard surfaces, so a centre punch is still advised for critical hole placement.

Questions about this item
How small is the 1/16 inch cobalt steel bit before it risks snapping under sustained pressure?
The 1/16 inch diameter and 7/8 inch flute length concentrate torque on a very small cross-section, so the bit will snap first if feed pressure is not reduced.
Does the straw/bronze finish keep the bit cool enough for all-day drilling in steel?
The finish helps identify the cobalt grade but does not dissipate heat; without through-coolant the bit will heat up quickly during continuous use.
What shank size must my drill chuck accept to hold this bit?
The shank diameter is 1/16 inch, so the chuck must close down to at least that size.
