Cleveland C71212 Jobber Length Drill Bit 1.6 Mm Hss

Product Description

The CLEVELAND C71212 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastics. It measures 1.6 mm (0.0630 inches) in diameter with a 118-degree standard point angle and a right-hand spiral flute configuration. The bit is manufactured from high speed steel with an oxide finish that provides light corrosion resistance and reduces friction during cutting. Overall length is 1.693 inches, and the web is thinned and tapered to reduce thrust and improve chip clearance. This bit is installed by machinists, maintenance technicians, HVAC mechanics, plumbers, and electricians for general drilling tasks in production and field environments.

The C71212 is suited for light-duty to medium-duty drilling applications in ferrous and non-ferrous materials. Its jobber-length format makes it a standard choice for bench drill presses, hand drills, and CNC spindles where a compact, versatile bit is needed. The Series 2001G designation indicates compliance with DIN 338 and ASME B94.11M standards, making it appropriate for use in both domestic and metric-specified work environments. Sold individually, it is ordered in multiples of 12.

Key Features

• 1.6 mm (0.0630 inch) diameter with a diameter tolerance of -0.0005 to 0.0000 inches for consistent hole sizing
• 118-degree standard point angle suits a wide range of general-purpose materials
• High speed steel construction with oxide coating for reduced friction and light corrosion resistance
• Web-thinned and tapered web design lowers thrust requirements and improves chip evacuation
• Two-flute regular spiral geometry with a 4xD flute-to-diameter ratio for efficient chip clearing
• Meets ASME B94.11M and DIN 338 standards for dimensional accuracy and performance

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard straight-shank drill chucks in hand drills, drill presses, and CNC machining centers that accept a 0.0630-inch straight-cylindrical shank.

Installation Notes

Installation requires a drill chuck sized to accept a straight-cylindrical shank of 0.0630 inches in diameter. Secure the chuck firmly before operating and confirm the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life. Inspect the cutting edges for wear before each use and replace the bit if the point is chipped or the flutes are clogged.
