Precision Twist Drill 6000716 Hss Jobber Drill Bit 2.50mm

Product Description

The PRECISION TWIST DRILL 6000716 is a jobber-length twist drill bit designed for general-purpose drilling in metal fabrication, HVAC rough-in, plumbing, and electrical trade work. Ground from high-speed steel (HSS) with a bright uncoated finish, it cuts a 2.50 mm (0.0984 inch) diameter hole at a standard 118-degree split point angle. The straight shank and regular spiral flute geometry suit most 3-jaw chucks and drill drivers. Overall length is 57.00 mm (2.2441 inches), with a flute length of 30.00 mm (1.1811 inches), giving a maximum drilling depth of 1.1811 inches. The web-thinned, tapered web reduces feed force and walking on entry.

This bit is rated for aluminum, non-ferrous metals, and general-purpose materials, making it a practical choice for drilling sheet metal, copper tube straps, aluminum enclosures, and similar trade materials. The Series 2A designation follows DIN 338 and ANSI standards, confirming dimensional consistency for production and service work. Sold individually, it fits applications where a single precision-ground bit is needed for a specific hole size without purchasing a full set.

Key Features

• 2.50 mm (0.0984 inch) diameter, jobber-length format for reach in standard drill chucks
• 118-degree standard point angle with web-thinned, tapered web for reduced entry force
• HSS construction with bright uncoated finish suitable for aluminum and non-ferrous materials
• Right-hand cut, regular spiral flute with 12xD flute-to-diameter ratio
• Straight shank, 0.0984 inch shank diameter — fits standard 3-jaw chucks without a reducer
• DIN 338 and ANSI compliant, Series 2A — consistent dimensional tolerances across production runs

Compatibility

Designed as a general-purpose jobber-length drill bit for use with standard drill presses, hand drills, and drill drivers equipped with 3-jaw chucks accepting straight-shank bits in the 0.0500 to 0.1000 inch size range.

Installation Notes

A licensed or qualified tradesperson should secure the workpiece firmly before drilling to prevent the bit from grabbing on breakthrough. Use cutting fluid or appropriate lubricant when drilling non-ferrous metals to extend bit life and maintain hole quality. Ensure the drill chuck is tightened fully and the bit runs true before applying feed pressure. Discard bits that show heat discoloration, chipped cutting edges, or loss of point geometry, as these conditions affect hole accuracy and can damage workpieces.
