Chicago-Latrobe 78594 Drill

The Chicago-Latrobe 78594 is a solid carbide straight flute drill bit manufactured for precision hole making. It suits machinists and technicians who require a rigid, wear-resistant tool for accurate drilling operations.

5/32 in Capacity and Headroom

The 5/32 in fractional size provides a decimal equivalent of .15625 in with a 1 in flute length for standard reach. The 140 degree point angle and four-facet design deliver strong centring and chip control in suitable materials, while the uncoated bright finish performs best in non-ferrous or low-alloy applications where coating adhesion is not required.

Bright Finish Carbide Tool Fit

The straight flute geometry demands a rigid machine setup and constant feed to avoid chatter, making it unsuitable for hand-held or low-stiffness equipment. The solid carbide construction handles higher speeds than high-speed steel but requires coolant or air blast to clear chips from deep holes, freeing the operator from frequent peck cycles in appropriate materials.

Questions about this item

Will this 140 degree point angle 5/32 in carbide drill work in a standard three-jaw chuck drill press?

Yes, the straight flute design and fractional inch shank fit standard three-jaw chucks on drill presses and hand drills.

How can I confirm the 140 degree point is cutting correctly after installation?

The four-facet point should produce clean holes with minimal burr at the 0.15625 decimal size when fed at proper carbide speeds.

Does the 78594 drill come with any coating or lubricant in the package?

The bright uncoated finish ships as a single drill bit; cutting fluid or lubricant must be purchased separately.
