Drill Bit 27/32 in Cobalt
This Chicago-Latrobe 53454 drill bit is a Silver & Deming style cutter with a 27/32 inch diameter and a 118 degree point angle. It is made from machining cobalt for hardness and heat resistance. The reduced 1/2 inch shank allows use in standard drill chucks. Machinists and maintenance technicians choose this bit for enlarging existing holes in tough metals.
Upgrade From Standard High-Speed Steel
Cobalt construction outperforms basic high-speed steel when drilling stainless steel, cast iron or other abrasive alloys. The jump is worth it when standard bits dull quickly or wander on hard materials. The 118 degree point provides a conventional cutting action suited to general-purpose drilling rather than specialised self-centring tasks. Builders who need a second bit for a different diameter should select the matching size.
Fits Standard Chucks No Adapter Needed
The 1/2 inch reduced shank seats directly in common three-jaw chucks without sleeves or bushings. Installation is a simple insert-and-tighten action. What usually goes wrong is insufficient clamping pressure on the reduced shank, which lets the bit slip under heavy feed. Ensure the chuck jaws grip the shank flats firmly and use cutting fluid to manage heat in deep holes.

Questions about this item
Will the 1/2 reduced shank fit my 1/2-inch drill chuck?
Yes, the reduced shank is sized for a standard 1/2-inch chuck, allowing the 27/32-inch bit to be used without a larger capacity drill.
How do I secure the 118-degree point angle bit so it does not spin in the chuck?
Tighten the chuck firmly on the flat sections of the 1/2 reduced shank rather than the round body; the flats prevent the bit from slipping under load.
When will the straw-bronze finish on the cobalt bit need replacement?
Replace the bit when the cutting edges become dull or chipped; the finish is a surface treatment that wears away as the cobalt material is sharpened or consumed.
