Chicago-Latrobe 78598 Drill
The Chicago-Latrobe 78598 is a solid carbide straight flute drill bit sized at 7/32 in. It features a 140 degree point angle and a bright uncoated finish. The decimal equivalent is .21875 and the flute length is 1 1/4 in. It is designed for general purpose machining applications.
Machinists needing 140° point
This drill suits machinists who require a 140 degree point angle for specific material engagement. The solid carbide construction offers rigidity for precise holemaking. It is not for operators who need a coated tool for extended life in abrasive alloys. Buyers requiring a different flute length or point geometry should look at other options.
Simple collet installation
Installation involves securing the straight shank into a compatible collet or drill chuck. The 4 facet point design aids self-centering at the workpiece. Problems usually arise from excessive runout in the holder or incorrect feed rates for carbide. Proper coolant use prevents premature wear on the uncoated surface.

Questions about this item
What size drill chuck is needed to hold the 7/32 inch shank?
A chuck with a minimum capacity of 7/32 inch or larger is required to grip the shank securely.
How does the 140 degree point angle affect drilling in harder materials compared to standard bits?
The 140 degree point angle is designed for harder materials and reduces the tendency to walk or skate on the surface when starting a hole.
What visible feature confirms the drill is the correct 7/32 inch size before use?
The fractional size 7/32 inch is marked on the shank; verify this marking matches the decimal equivalent 0.21875 inch required for the job.
