Precision drill bit for carbide machining
The Chicago-Latrobe 78595 is a solid carbide straight flute drill sized at 11/64 inch with a 140-degree point angle. Its 4 facet point geometry provides accurate hole starts in hard materials. The bright uncoated finish suits general-purpose machining where coating is not required. This fractional inch bit targets machinists drilling abrasive or high-temperature alloys.
Straight flute limits chip evacuation in deep holes
The straight flute design cannot lift chips effectively beyond shallow depths, so holes deeper than the 1 1/16 inch flute length risk packing and tool failure. Carbide's brittleness demands rigid setups; any runout or vibration will cause chipping. Uncoated carbide wears faster in stainless steel or titanium than coated alternatives. Coolant pressure must reach the cutting zone to prevent built-up edge.
11/64 inch diameter fixes the hole size
The 0.171875 inch decimal equivalent means this bit produces one specific hole diameter only. Shops needing a different size must select another tool. The 140-degree point angle is optimised for harder materials; softer metals may benefit from a steeper angle. Verify your machine's collet or chuck accepts this shank before ordering.

Questions about this item
Should I choose the 11/64 in 140° solid carbide drill or a different size?
The 11/64 in size equals .171875 in decimal; select it when your hole requirement matches this exact fractional diameter.
What does the 140° point angle mean when the drill is in the machine?
A 140° point with four facets centres itself in hard materials and reduces thrust, letting the solid carbide body cut cleanly without wandering.
Does the straight-flute design cap the drill to certain machines or standards?
Straight flutes suit rigid setups such as drill presses or CNC spindles; they are not designed for hand-held use where chip evacuation relies on helix flutes.
