Precision Cobalt Drill Bit

The Chicago-Latrobe 53453 is a 53/64 inch cobalt drill bit built for heavy-duty metalworking. Its 118-degree point angle and reduced 1/2 inch shank allow it to fit standard large-capacity drill chucks while delivering the heat resistance of cobalt steel.

Workshop vs Production Use

This bit suits maintenance technicians and fabricators drilling large-diameter holes in steel or cast iron where cobalt's durability reduces changeovers. It is not for users needing a smaller shank to fit 3/8 inch chucks or those drilling primarily in wood, plastics or thin sheet metal where high-speed steel is adequate.

53/64 Inch Diameter

The single specification that decides fit is the 53/64 inch cutting diameter; verify the hole size against your drawings or tap charts before purchase. The 1/2 inch reduced shank determines chuck compatibility, so confirm your drill accepts this shank size.

Questions about this item

How much heat does the 118° cobalt bit generate during extended drilling?

The 118° point angle on the cobalt material is designed to reduce heat buildup compared to standard high-speed steel bits.

What chuck size is required for the 1/2 reduced shank on the 53453?

The 1/2 reduced shank fits any standard drill chuck with a 1/2 inch or larger capacity.

Will the 53/64 in size work with my older 1/2 inch drill press?

Yes, the 1/2 reduced shank allows the 53/64 in bit to be used in older drill presses with a 1/2 inch chuck.
