Precision Twist Drill 6000738 Jobber Drill Bit 0.1299 in

Product Description

The PRECISION TWIST DRILL 6000738 is a jobber-length twist drill bit designed for general-purpose hole making in a wide range of materials. Ground from high speed steel with a bright uncoated finish, it measures 0.1299 inches in diameter and runs to an overall length of 2.5591 inches, keeping it within standard jobber proportions. The 118-degree standard point angle suits the majority of common drilling applications, and the web-thinned, tapered-web construction reduces entry force at the tip. Two spiral flutes with a regular helix evacuate chips efficiently during through-hole and blind-hole work. Machinists, maintenance technicians, and fabricators reach for this bit when drilling steel, stainless steel, cast iron, non-ferrous metals, and superalloys.

This drill bit is suited for use in hand drills, drill presses, CNC machining centers, and manual lathes where a straight-cylindrical shank is accepted. It conforms to DIN 338 and ANSI standards, making it a direct fit in applications that specify those designations. The Series 2A classification places it in the standard jobber-length family, appropriate for general shop and field service work across metal fabrication, HVAC, plumbing, and electrical trades where pilot holes, clearance holes, and through holes in metal are required regularly.

Key Features

• High speed steel construction handles steel, stainless steel, cast iron, non-ferrous metals, and superalloys
• 118-degree standard point angle for general-purpose drilling across common workpiece materials
• Web-thinned, tapered-web tip reduces cutting force and improves centering at entry
• Two spiral flutes with regular helix promote consistent chip evacuation
• Straight-cylindrical shank at 0.1299 inches diameter fits standard drill chucks without adapters
• Conforms to DIN 338 and ANSI specifications for dimensional consistency and interchangeability

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any drill chuck or collet system that accepts a 0.1299-inch straight-cylindrical shank. Suitable for use in hand drills, drill presses, and machining centers across metal fabrication and trade service applications.

Installation Notes

Secure the shank fully in the chuck and tighten with a chuck key before operating. Confirm the workpiece is clamped or fixtured before beginning a cut to prevent bit walking or workpiece movement. Apply cutting fluid or lubricant when drilling stainless steel, cast iron, or superalloys to extend tool life and reduce heat buildup. Do not exceed the maximum drilling depth of 1.4173 inches without clearing chips from the flutes.
