Chicago-Latrobe 44918 Cobalt Drill Bit
The Chicago-Latrobe 44918 is a jobber length drill bit made from cobalt steel with a TiAlN coating. It is designed for drilling tough materials such as stainless steel and high-temperature alloys. The split point tip improves starting accuracy and reduces walking on hard surfaces.
For Machinists Drilling Hard Metals
This bit suits machinists and maintenance technicians who regularly drill work-hardening metals where standard high-speed steel wears quickly. It is not for woodworkers or general DIY users drilling soft materials, nor for operations requiring coolant-through tooling.
135 Degree Split Point Geometry
The 135 degree split point is the specification that determines suitability for hard, work-hardening alloys. It reduces thrust force and prevents the bit from walking on contact, a critical advantage when drilling stainless steel or similar materials.

Questions about this item
What does the 135 degree split point do for the 9/32 in cobalt bit?
The 135 degree split point reduces walking and starts holes faster in hard materials such as stainless steel and titanium alloys.
What shank size does the 9/32 in jobber length drill bit have?
The shank matches the 9/32 in drill diameter, so it fits any standard three-jaw chuck that accepts 9/32 in or larger.
How do I install the 9/32 in cobalt drill bit without damaging the TiAlN coating?
Insert the bit fully into the chuck, tighten all three jaws evenly, and avoid side pressure while drilling to keep the coating intact.
