Chicago-latrobe 68814 7/32 Inch Taper Length Drill Bit Hss

Product Description

The CHICAGO-LATROBE 68814 is a taper length drill bit designed for heavy-duty drilling in metal fabrication and machining applications. Built from high speed steel with a bright/uncoated finish, this bit features a 135-degree split point that promotes self-centering and reduces walking on entry, eliminating the need for a center punch in most setups. The parabolic flute geometry accelerates chip evacuation, making it well-suited for deeper holes and interrupted cuts. At 7/32 inch (0.2188 inches) in diameter with a 6-inch overall length and a 4.375-inch flute length, it provides extended reach beyond standard jobber-length bits. The tanged shank and tapered web design add rigidity during high-feed operations. Machinists, tool-and-die technicians, and fabricators rely on this Series 120DH bit for consistent, accurate performance in demanding production environments.

The CHICAGO-LATROBE 68814 is suited for drilling alloy steel, carbon steel, aluminum, and other non-ferrous metals in both manual and CNC machine tool setups. The taper length body is a common choice when standard jobber bits lack the reach for fixtures, deep bores, or multi-stack drilling. Right-hand cut geometry matches conventional drill press and lathe spindle rotation. The self-centering split point reduces thrust requirements, which benefits operators working on sensitive workpieces or lower-horsepower machines.

Key Features

• 135-degree split point for self-centering entry without a center punch
• Parabolic flute design improves chip flow and reduces heat buildup in deep holes
• High speed steel construction rated for heavy-duty metal drilling
• Taper length body at 6 inches OAL provides extended reach over jobber-length bits
• Web-thinned tapered web reduces cutting resistance and improves drill life
• Bright/uncoated finish maintains as-ground sharpness with no coating to chip or flake

Compatibility

Designed for use in standard drill presses, CNC machining centers, and manual lathes accepting a tanged taper shank. Compatible materials include alloy steel, aluminum, carbon steel, and non-ferrous metals per Series 120DH application data.

Installation Notes

A licensed machinist or qualified fabricator should verify spindle taper compatibility before mounting the tanged shank. Secure the shank fully in the taper socket and confirm zero runout before beginning the cut. Always wear appropriate eye protection and secure the workpiece before drilling. Inspect the cutting edges for wear or chipping before each use and redress or replace the bit as needed to maintain diameter tolerance of +0.0000 to -0.0007 inches.
