Chicago-Latrobe 78590 3/32 in 140 Degree Solid Carbide Straight Flute Drill

Chicago-Latrobe 78590 Solid Carbide Drill

This Chicago-Latrobe 78590 drill bit is a solid carbide cutting tool sized at 3/32 in with a 140 degree point angle. It suits machinists and maintenance technicians who need a rigid, wear-resistant bit for precise hole-making in tough materials. The bright, uncoated finish and four-facet point geometry support accurate centring and chip evacuation in general-purpose drilling applications.

Sustained cutting performance

Solid carbide construction maintains hardness at elevated temperatures, so the bit resists softening during extended drilling cycles better than high-speed steel alternatives. The straight flute design and 3/4 in flute length provide a consistent chip path, reducing the risk of clogging when the tool runs continuously in deeper holes. A 140 degree point angle distributes cutting forces evenly, helping the edge stay sharp over long production runs.

Build quality and daily use

The bright uncoated surface eliminates coating delamination concerns and allows easy visual inspection of the cutting edges for wear. A fractional 3/32 in diameter with a 0.09375 decimal equivalent fits standard collets and drill chucks without adaptation. The four-facet point is regrindable, extending service life for shops that maintain their own tooling inventory.
