Chicago-Latrobe 78592 Carbide Drill
This solid carbide straight flute drill measures 1/8 in with a 140 degree point angle. The bright uncoated finish suits general-purpose drilling. A 4-facet point design helps with accurate starts. The flute length is 7/8 in for effective chip clearance.
For machinists needing a rigid carbide bit
It suits users drilling steel, cast iron or non-ferrous metals where rigidity matters. The straight flute design is not for deep-hole work or materials needing polished flutes for chip evacuation. Buyers who need coolant-fed or coated drills should look elsewhere.
140 degree 4-facet point angle
This point geometry determines how the drill enters the workpiece and reduces walk. The 140 degree angle with four facets suits harder materials and improves centring. Verify the point angle matches your application before ordering.

Questions about this item
How do I install the 78592 drill bit and what step do people often get wrong?
Chuck the 1/8 in shank securely in a drill press or hand drill, then start the hole at low RPM with steady pressure; the step users miss is centre-punching the workpiece first so the 140 degree point does not wander on hard material.
What maintenance or replacement will the 78592 carbide drill need later?
The solid carbide body cannot be resharpened with standard shop stones; once the 4 facet cutting edges dull you replace the bit rather than regrind it.
What limit appears first on the 78592 during sustained drilling?
Heat builds quickly in uncoated carbide, so the 7/8 in flute length can clog with chips and overheat the cutting edges before the bit wears out.
