Chicago-Latrobe 53456 Cobalt Drill Bit

This Chicago-Latrobe 53456 drill bit is a 7/8 inch Silver & Deming style tool with a 1/2 inch reduced shank. It features a 118 degree point angle and a straw bronze finish on machining cobalt material. The design allows use in standard drill chucks that cannot accommodate larger straight shanks.

Suited for machinists needing large holes in metal

This bit suits machinists and maintenance technicians drilling 7/8 inch holes in steel or alloy where a 1/2 inch chuck is the largest available. The cobalt construction handles high heat during deep cuts. Buyers who need a straight shank for a larger chuck or a different point angle for specialised materials should look elsewhere.

7/8 inch diameter with 1/2 inch reduced shank

The defining specification is the 7/8 inch cutting diameter paired with a 1/2 inch reduced shank. This combination determines whether the bit fits your chuck and produces the required hole size. Verify both dimensions match your equipment and application before purchasing.

Questions about this item

Does the Chicago-Latrobe 53456 drill bit come individually or do I need to buy a set separately?

The Chicago-Latrobe 53456 is supplied as a single reduced-shank drill bit. No additional pieces are included, so nothing else is required to use it.

Which point angle version should I choose for general-purpose metal drilling?

This model has a fixed 118 degree point angle, which is the standard geometry for general-purpose drilling in metal and other materials.

How does the 118 degree point angle perform when the bit is mounted in a 1/2 inch chuck?

The 118 degree point centres quickly and cuts efficiently in metal, while the 1/2 reduced shank fits standard drill chucks without needing a larger capacity chuck.
