Cleveland C71298 Jobber Length Drill Bit 9.3 Mm Hss

Product Description

The CLEVELAND C71298 is a jobber-length twist drill bit designed for general-purpose metal drilling in production and maintenance environments. Built from high speed steel with an oxide coating, this bit offers improved lubricity and corrosion resistance during drilling operations. It measures 9.3 mm (0.3661 inches) in diameter with an overall length of 4.921 inches and a flute length of 3.189 inches. The 118-degree standard point angle suits a wide range of common metal-cutting applications. The bit features a web-thinned, tapered web design that reduces thrust force at entry and improves chip clearance. Licensed trades and machining professionals are the typical end users for this type of tooling.

This drill bit is well-suited for general-purpose drilling in steel, aluminum, and similar materials in both shop and field settings. The two-flute spiral design with regular helix promotes efficient chip evacuation during through-hole and blind-hole operations. The straight cylindrical shank allows use in standard drill chucks and machine spindles. It conforms to ASME B94.11M and DIN 338 specifications, placing it in the 9.00 mm to 10.00 mm diameter size range class. Series 2001G, this bit is appropriate for maintenance, fabrication, and light production drilling tasks.

Compatibility

Designed for use in standard drill chucks and machine spindles accepting a 0.3661-inch straight cylindrical shank. Suitable for general-purpose drilling in ferrous and non-ferrous metals within the 9.00 mm to 10.00 mm diameter class.

Installation Notes

Secure the straight cylindrical shank fully in a calibrated drill chuck before operation. De-energize and lock out any machine tool before changing or inspecting the bit. Use appropriate cutting fluid for the material being drilled to extend bit life and improve hole quality. Dispose of worn bits per applicable shop safety protocols.
