Industrial Drilling Capacity

The Chicago-Latrobe 53462 is a cobalt drill bit sized at 31/32 in with a 118 degree point angle. It targets machinists and maintenance technicians who need to enlarge or create holes in tough alloys. The straw-bronze finish identifies the cobalt construction. Reduced shank geometry allows use in standard half-inch chucks.

Chuck Compatibility Check

Verify that your drill press or handheld drill accepts a half-inch reduced shank before ordering. The bit diameter exceeds the shank diameter, so the chuck must open wide enough for the larger body. Confirm the spindle runout is low enough for cobalt tooling. Ensure the workpiece material suits a 118 degree point profile.

Cobalt Build and Shank Implications

Cobalt material resists heat and wear better than high-speed steel during prolonged cuts. The 118 degree point centres quickly but requires steady feed pressure to avoid walking. Reduced shank design transfers torque through a smaller cross-section, so avoid excessive side loads. Straw-bronze surface helps identify the bit in a mixed tray.

Questions about this item

Does the Chicago-Latrobe 53462 drill bit come alone or in a set, and is a 1/2 inch chuck required?

The 53462 is a single Silver & Deming drill bit with a 1/2 inch reduced shank, so it fits directly into a 1/2 inch drill chuck without extra sleeves.

How do I decide between the 31/32 inch size and other diameters in this cobalt line?

Choose the 31/32 inch bit when the hole must be that exact diameter; other sizes in the range serve different finished-hole requirements.

What does the 118 degree point angle mean when I drill steel with this cobalt bit?

The 118 degree point is a general-purpose geometry that centres quickly in steel and works well in portable drills without walking.
