Jobber-Length Cobalt Drill Bit
The Chicago-Latrobe 46610 is a jobber-length drill bit made from cobalt steel for drilling hard metals. Its 135-degree split point reduces walking and starts holes cleanly without a centre punch. The fractional 5/32-inch size suits general maintenance and fabrication tasks.
Fits Standard Chucks and Drill Presses
The straight shank fits any three-jaw chuck or drill press collet that accepts jobber-length bits. No coolant holes are present, so the bit relies on external lubrication or peck drilling for heat control. The straw-bronze surface finish helps identify the tool in a busy kit.
Ready to Use with No Extra Parts
The bit ships as a single cutting tool with no pilot drills, depth stops or coating kits included. The split-point geometry eliminates the need for a separate centre drill in most materials. Free shipping applies only on orders of $75 or more, a condition set by the supplier.

Questions about this item
How does the 135-degree split point affect drilling performance?
The 135-degree split point reduces walking and allows faster penetration without a centre punch, especially in hard metals.
Does the cobalt construction run hotter than standard high-speed steel during extended use?
Cobalt alloy retains hardness at higher temperatures, so the bit stays sharp longer under sustained drilling.
What chuck size is required to hold the 5/32-inch shank?
A standard three-jaw chuck that opens to at least 5/32 inch (0.1563 in) will grip the jobber-length shank securely.
