Cleveland C01037 Jobber Drill Bit Wire 68 Hss 118 Degree

Product Description

The CLEVELAND C01037 is a jobber-length twist drill bit in wire gauge size 68, with a decimal diameter of 0.0310 inches. It is ground from high speed steel (HSS) and finished with a black oxide coating that provides moderate lubricity and corrosion resistance during cutting. The 118-degree standard point angle is the conventional geometry for general-purpose drilling in ferrous and non-ferrous materials. With an overall length of 1-3/8 inches and a 1/2-inch flute length, this bit is sized for light-duty, small-diameter work. The two-flute spiral design with a tapered web and web-thinned tip reduces thrust and improves chip evacuation. Licensed machinists, maintenance mechanics, and tool-and-die technicians are the primary installers.

The C01037 is suited for precision drilling operations in cast iron and steel where tight hole tolerances and consistent chip clearing are required. The straight cylindrical shank seats directly in standard drill chucks, collets, and drill press spindles without additional adapters. Its compact jobber length makes it well-suited for use in benchtop drill presses, CNC drilling centers, and handheld power drills where clearance is limited. The general-purpose grade and ASME B94.11M and DIN 338 compliance make it appropriate for both production and maintenance environments.

Key Features

• Wire size 68 with 0.0310-inch decimal diameter and diameter tolerance of -0.0005 to 0.0000 inches for consistent close-tolerance holes
• 118-degree standard point angle with web-thinned, tapered web geometry for reduced entry thrust
• High speed steel construction with black oxide finish for moderate heat and corrosion resistance
• Two-flute regular spiral design promotes efficient chip evacuation from small-diameter bores
• Straight cylindrical shank at 0.0310-inch diameter fits standard drill chucks and collets
• Meets ASME B94.11M and DIN 338 standards for jobber-length drill bit geometry

Compatibility

Designed as a general-purpose jobber-length drill bit for use in cast iron and steel workpieces. Compatible with any standard drill chuck or collet accepting a 0.0310-inch straight cylindrical shank.

Installation Notes

This bit is installed by machinists or maintenance technicians in standard drill chucks or precision collets. Ensure the chuck or collet is clean and the shank is fully seated before tightening to prevent runout. Secure the workpiece firmly before drilling to avoid bit deflection or breakage at this small diameter. For small-diameter HSS bits, use appropriate cutting fluid on ferrous materials to extend tool life and maintain hole quality.
