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.

Questions about this item
Does the 140-degree point angle on the 78590 drill bit reduce cutting force and heat during extended use?
The 140-degree point angle on this solid carbide drill bit is designed to reduce cutting force and heat buildup during prolonged drilling operations.
What tool holder or chuck is required to use the 3/32 inch straight flute drill bit?
A standard drill chuck or collet that accepts a 3/32 inch (0.09375 decimal equivalent) shank is required to secure this straight flute drill bit.
Will the bright uncoated finish on this carbide drill work effectively in older drill presses with lower spindle speeds?
The bright uncoated finish and 4-facet point design perform well in older drill presses, though optimal results require appropriate speed and feed rates for carbide tooling.
