Chicago-Latrobe 53442 Cobalt Drill Bit
This Chicago-Latrobe 53442 drill bit is a Silver & Deming style tool made from cobalt steel with a straw bronze finish. It features a 118 degree point angle and a reduced 1/2 inch shank for use in larger drill chucks. The bit is designed for drilling 21/32 inch diameter holes in tough materials. It suits machinists and maintenance technicians who need durable performance in metalworking applications.
Check Shank Compatibility Before Ordering
Verify that your drill press or heavy-duty hand drill accepts a 1/2 inch reduced shank before purchasing this bit. The 21/32 inch cutting diameter requires a machine with sufficient power and rigidity to handle the load. Ensure the tool holder or chuck can securely clamp the reduced shank without slippage during operation. Confirm the workpiece material is suitable for cobalt steel tooling and the 118 degree point geometry.
Cobalt Construction and Reduced Shank Design
The cobalt steel construction offers high heat resistance and wear resistance for extended tool life in abrasive or hard metals. The straw bronze finish helps identify the cobalt material and provides some corrosion protection. The reduced shank allows this large diameter bit to fit standard 1/2 inch capacity chucks on bench or floor drill presses. The 118 degree point is a general purpose geometry suitable for a wide range of ferrous and non-ferrous metals.

Questions about this item
Does the Chicago-Latrobe 53442 cobalt drill bit come alone or in a set, and is a 1/2 inch chuck required?
The item is sold as a single 21/32 inch cobalt steel bit with a 1/2 inch reduced shank; a drill chuck that accepts 1/2 inch shanks must be supplied separately.
Should I choose this 21/32 inch size or another diameter for a 1/2 inch reduced shank?
This model 53442 is the 21/32 inch diameter; other diameters in the same reduced-shank series carry different part numbers, so select the size that matches the hole you need to drill.
How does the 118 degree point angle affect drilling in stainless steel with this cobalt bit?
The 118 degree point is a general-purpose geometry that centres well in steel; cobalt steel holds its edge at higher temperatures, making it suitable for stainless and other hard alloys.
