1/16 in carbide straight-flute drill
The Chicago-Latrobe 78588 is a solid-carbide straight-flute drill bit sized at 1/16 in. It is built for machinists and maintenance technicians who need a rigid, wear-resistant tool for producing accurate small-diameter holes in hardened alloys, stainless steel and other abrasive materials.
Upgrade from high-speed steel drills
Carbide construction replaces conventional high-speed steel bits when longer tool life and tighter hole tolerance are required. The jump is worth it for repetitive production runs or difficult-to-machine workpieces where frequent resharpening of HSS drills would interrupt workflow.
Handles small-diameter precision drilling
The 140-degree four-facet point and 5/8 in flute length give reliable centring and chip evacuation in holes up to the flute depth. The uncoated bright finish performs well in short-chipping materials but offers less heat resistance than coated alternatives in prolonged high-speed cuts.

Questions about this item
What size chuck does the 1/16 in 78588 drill bit fit?
The bit has a 1/16 in diameter shank, matching standard fractional-inch drill chucks that accept 0.0625 in sizes.
How should I start the 140° point on hard material to avoid walking?
Use a centre punch mark and low RPM with steady pressure; the four-facet 140° point self-centres but will skip if the surface is smooth and unmarked.
When does the solid carbide 78588 bit need replacement?
Replace when the cutting edges show chipping, the 5/8 in flute clogs persistently, or hole diameter exceeds tolerance — carbide cannot be resharpened economically.
