Cleveland C71285 Jobber Length Drill Bit 8 Mm Hss

Product Description

The CLEVELAND C71285 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastics. Built from high speed steel (HSS) with an oxide coating, the bit resists heat and wear through moderate-duty production and maintenance applications. It measures 8 mm (0.3150 inches) in diameter with an overall length of 4.606 inches and a flute length of 2.953 inches. The 118-degree standard point angle and web-thinned tip reduce thrust requirements at entry, making this bit suitable for hand-fed drill presses, CNC drilling, and portable electric drills used by maintenance technicians, machinists, and fabricators.

This bit is appropriate for residential and light commercial shop environments where standard tolerances are acceptable. The straight-cylindrical shank fits standard three-jaw drill chucks without adapters. The Series 2001G designation places it within a broad general-purpose family commonly stocked in maintenance, repair, and operations (MRO) settings. The right-hand spiral flute evacuates chips efficiently during through-hole and blind-hole operations across a range of workpiece materials.

Key Features

• High speed steel construction with oxide coating for heat and wear resistance
• 118-degree standard point angle with web-thinned tip to reduce entry thrust
• Regular spiral, 2-flute design for efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks without adapters
• Meets ASME B94.11M and DIN 338 dimensional standards
• No coolant-through requirement — suitable for dry or flood-coolant use

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard three-jaw chuck accepting a 0.3150-inch straight-cylindrical shank, including bench drill presses, radial arm drills, and portable electric drills.

Installation Notes

Installation and use should follow standard machining safety practices. Secure the workpiece firmly before drilling and confirm the chuck is fully tightened before applying power. Ensure the drill speed (RPM) is appropriate for the workpiece material and bit diameter — consult published speed-and-feed tables for HSS tooling. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is damaged to prevent workpiece damage or bit breakage.
