Chicago-Latrobe 15/32 in Cobalt Drill Bit
This Chicago-Latrobe screw machine drill bit measures 15/32 in and is made from cobalt steel for extended wear resistance. The 135-degree split point reduces walking and starts holes cleanly in tough alloys. Right-hand cutting direction suits standard drill motors and CNC spindles. It is aimed at machinists and maintenance crews who need repeatable hole accuracy.
Decimal .4688 in capacity with cobalt headroom
The bit cuts a precise .4688 in diameter hole and the cobalt substrate keeps its edge longer than high-speed steel in stainless or high-tensile steels. The split-point geometry centres the cut without a centre punch, saving setup time on repetitive jobs. Non-coolant-through design means it relies on external flood or mist lubrication. In very deep holes chip evacuation can become the limiting factor.
Straw finish and straight shank for daily shop use
A straw-coloured surface treatment identifies the cobalt grade and adds a thin lubricity layer during break-in. The straight shank fits three-jaw chucks, collets and quick-change holders without adapters. No through-coolant channel keeps the body simple and rugged for hand-held or fixed-spindle work. Build quality is consistent with Chicago-Latrobe’s industrial reputation.

Questions about this item
Does the 135-degree split point on this 15/32-inch bit work with the same drill press I use for standard twist bits?
The 135-degree split point is designed for self-centering starts in harder materials and fits any standard chuck that accepts a 15/32-inch shank.
How can I verify the cobalt bit is cutting correctly once installed?
A properly cutting cobalt bit produces tight, straw-coloured chips rather than powder, advances steadily under moderate pressure, and leaves a clean hole at the 0.4688-inch decimal size.
What comes in the package and is anything else required to use it?
The box contains the single 50827 screw-machine drill bit; no coolant or additional accessories are included, so have cutting fluid ready if the application calls for it.
