Chicago-Latrobe 50849 Drill Bit
The Chicago-Latrobe 50849 is a screw machine drill bit manufactured for precision drilling tasks. It suits machinists and maintenance technicians who require accurate hole sizing in metalworking applications.
135-Degree Split Point Cobalt
The cobalt construction provides heat resistance and durability when drilling harder materials. A 135-degree split point reduces walking and allows the bit to start on contact. The decimal equivalent is .3580 inches, giving a precise reference for hole tolerances.
Right-Hand Cutting Non-Coolant Through
This bit replaces worn or general-purpose drills when a right-hand cutting direction and non-coolant-through design are specified. The jump is worth it for operators who need the straw finish and split-point geometry for consistent performance in screw machine operations.

Questions about this item
Will the 135-degree split point on this cobalt bit start cleanly in the same drill press I use for standard high-speed steel bits?
Yes, the 135-degree split point is self-centering and reduces walking, so it works in any standard drill press or hand drill without needing a centre punch.
How can I confirm the bit is cutting correctly once I start drilling?
A properly working bit produces short, curled chips rather than long stringers, and the straw-coloured cobalt surface should stay gold without turning blue from overheating.
Does the box include any cutting fluid or a holder for the 0.3580-inch T-size bit?
The package contains only the single cobalt screw-machine drill bit; cutting fluid and a drill chuck or collet must be supplied separately.
