Chicago-Latrobe 53440 Cobalt Drill Bit

The Chicago-Latrobe 53440 is a cobalt steel drill bit with a 118 degree point angle. It features a reduced shank designed for use in power tools with smaller chuck capacities. The straw bronze finish identifies the machining cobalt material.

Suited for tough metal drilling tasks

This bit suits machinists and maintenance staff drilling hard metals such as stainless steel or cast iron. The cobalt construction resists heat and wear during extended use. It is not for buyers who need a split point for self-centring or a different point angle for specialised materials.

118 degree point angle for general purpose drilling

The 118 degree point angle is the critical specification that defines this bit's cutting action. This angle provides a good balance for general purpose drilling across common ferrous metals. Verify that your application matches this geometry before purchase.

Questions about this item

Will the 1/2 inch reduced shank fit the chuck on my existing drill press?

The 1/2 inch reduced shank is designed to fit standard drill chucks with a 1/2 inch or larger capacity, allowing use with most common drill presses and heavy-duty hand drills.

Can the 118 degree point angle handle drilling through older, hardened steel workpieces?

The 118 degree point angle on this cobalt steel bit is suited for general-purpose drilling in metal, including harder alloys, though very hard materials may require slower speeds and cutting fluid.

How can I verify the bit is cutting correctly once I start drilling?

A properly functioning bit will produce continuous, helical chips rather than fine dust or discoloured fragments, and the straw/bronze finish should not show blue discolouration from overheating.
