Precision Twist Drill 6000725 Jobber Drill 2.90mm Hss

Product Description

The PRECISION TWIST DRILL 6000725 is a jobber-length twist drill bit designed for general-purpose drilling in production and maintenance applications. Built from high speed steel (HSS) with a bright, uncoated finish, it measures 2.90 mm (0.1142 inches) in diameter and carries a standard 118-degree point angle. The overall length is 2.4016 inches, with a flute length of 1.2992 inches. The two-flute, regular spiral geometry with a tapered web and web-thinned point promotes efficient chip evacuation and reduces thrust during entry. Licensed tradespeople and machinists reach for this bit when straight, accurate holes are needed in light-metal and non-ferrous workpieces.

This drill bit is suited for drilling aluminum, copper, brass, and other non-ferrous materials in light manufacturing, HVAC sheet metal work, plumbing rough-in, and electrical panel fabrication. The straight cylindrical shank fits standard 3-jaw drill chucks on hand drills, drill presses, and CNC machining centers without modification. The Series 2A designation and DIN 338 specification place this bit in a widely recognized dimensional standard, making it straightforward to source as a working replacement for worn or broken bits of the same size.

Key Features

• 2.90 mm (0.1142 inch) diameter with straight cylindrical shank of matching diameter
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• High speed steel construction for general-purpose durability across non-ferrous materials
• Regular spiral, two-flute design promotes clean chip evacuation during through-hole drilling
• Bright, uncoated finish — no coating buildup to affect dimensional tolerance
• Conforms to DIN 338 specification, Series 2A

Compatibility

Designed as a general-purpose jobber drill conforming to DIN 338 dimensions, compatible with any standard 3-jaw drill chuck accepting a 0.1142-inch straight cylindrical shank. Primary workpiece material suitability covers aluminum and non-ferrous metals per material codes P, M, K, N, and S.

Installation Notes

This drill bit is installed by tradespeople and machinists using a standard drill chuck; secure the shank fully and verify chuck tightness before operating. Ensure the workpiece is clamped or fixtured before drilling to prevent rotation and maintain hole accuracy. Use appropriate cutting fluid or lubricant when drilling non-ferrous metals to extend bit life and improve finish quality. Do not exceed the bit's rated maximum drilling depth of 1.2992 inches in a single pass without retracting to clear chips.
