Cleveland C72122 Jobber Drill Bit Wire 22 Hss 118 Degree

Product Description

The CLEVELAND C72122 is a jobber-length twist drill bit designed for general-purpose drilling in a wide range of materials. Manufactured from high speed steel (HSS) with a bright uncoated finish, this bit carries a wire gauge size of 22, equivalent to 0.1570 inches in diameter. The 118-degree standard point angle and web-thinned tip reduce entry force and improve chip clearing at the start of the cut. With an overall length of 3-1/8 inches and a 2-inch spiral flute, the C72122 delivers the reach and chip evacuation needed for common production and maintenance drilling tasks. It is sold individually per package.

The C72122 is suited for use in hand-held drills, drill presses, and light CNC applications where a straight-cylindrical shank and standard jobber-length geometry are appropriate. Its regular spiral and tapered web configuration make it a reliable choice for drilling mild steel, aluminum, plastics, and similar materials in shop, field, and light industrial settings. The general-purpose grade and HSS construction make it a standard replacement bit for maintenance technicians, machinists, and fabricators working across a variety of substrates.

Key Features

• Wire size 22 (0.1570 inches) straight-cylindrical shank for secure chuck retention
• 118-degree standard point angle with web-thinned tip for reduced entry force
• High speed steel construction suitable for general-purpose drilling applications
• Bright uncoated finish — no coating to chip or delaminate during regrinding
• Regular spiral, 2-inch flute length for efficient chip evacuation in jobber-depth holes
• Complies with ASME B94.11M and DIN 338 standards for jobber-length drill bits

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard 3-jaw chuck or collet system accepting a 0.1570-inch straight-cylindrical shank. Suitable for use with hand drills, drill presses, and light-duty machining centers requiring wire-gauge tooling.

Installation Notes

Insert the straight-cylindrical shank fully into the chuck and tighten securely before operation. Confirm spindle speed is appropriate for the workpiece material and bit diameter before starting the cut. Wear appropriate eye protection and secure the workpiece before drilling. Regrinding is possible given the bright uncoated finish, but web-thinning should be restored after each regrind to maintain cutting performance.
