What It Is
The Chicago-Latrobe 54060 is a jobber-length drill bit made from HAWA cobalt with a TiN coating. It has a 9/32 in diameter and a 135 degree split point for self-centering starts. The decimal equivalent is .2813 in. It is designed for general-purpose drilling in metal using handheld or stationary power tools.
Who It Suits
This bit suits machinists and maintenance technicians who need a durable cobalt tool for drilling stainless steel or other tough alloys. The split point reduces walking on hard surfaces. Buyers who need coolant-through capability for deep-hole drilling should look at a different style. Users requiring a larger or smaller diameter must select another size.
Deciding Specification
The 9/32 in fractional size is the single specification that determines fit for the required hole. The 135 degree point angle and cobalt construction support drilling in harder materials, but the diameter is the fixed value that must match the job. Verify the target hole size before purchase.

Questions about this item
What does the 135° split point do for drilling?
The 135° split point reduces walking and starts holes accurately in metal without a centre punch.
What shank size fits this 9/32 in jobber bit?
The shank matches the 9/32 in diameter so it fits any three-jaw chuck that opens to at least .2813 in.
How should I run this cobalt bit to avoid premature wear?
Use cutting fluid, keep RPM moderate for the material, and apply steady pressure — do not force the feed.
