Precision Twist Drill 6000393 Jobber Drill Bit Hss

Product Description

The PRECISION TWIST DRILL 6000393 is a high speed steel jobber-length drill bit designed for precision drilling in a wide range of metalworking applications. At 0.0236 inches in diameter with a standard 118-degree split point and web-thinned geometry, this bit delivers clean entry and consistent hole quality in small-diameter work. The bright, uncoated finish is standard for general purpose HSS tooling. With an overall length of 0.9449 inches and a straight-cylindrical shank, it seats securely in standard drill chucks and collet holders. Two spiral flutes provide chip evacuation during drilling operations.

This bit is suited for production and maintenance drilling on steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It conforms to DIN 338 and ANSI standards, placing it in a widely accepted dimensional series for jobber-length tooling. Series 2A designation indicates a general purpose performance tier appropriate for manual drill presses, CNC machining centers, and handheld drill applications where a sub-millimeter hole diameter is required. Right-hand cutting direction is standard for conventional drilling setups.

Key Features

• 0.0236 inch diameter with straight-cylindrical shank of equal 0.0236 inch diameter for direct chuck fit
• 118-degree standard point angle for general purpose metal drilling
• Web-thinned, tapered web construction reduces thrust and improves cutting efficiency at small diameters
• Two spiral flutes with regular helix for reliable chip clearance
• Bright, uncoated high speed steel finish compatible with cutting fluids and dry drilling
• Conforms to DIN 338 and ANSI standards for consistent dimensional interchangeability
• Maximum drilling depth of 0.2756 inches matching flute length

Compatibility

Designed as a general purpose jobber drill bit suitable for use in standard drill chucks, collet holders, and CNC tool holders accepting a 0.0236 inch straight-cylindrical shank. Compatible workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium per manufacturer specification.

Installation Notes

This bit is installed and used by machinists, tool and die technicians, and maintenance trades working with drill presses, milling machines, or handheld power drills. Ensure the shank is fully seated and the chuck is properly tightened before operation. At this diameter, use appropriate cutting fluid and low feed pressure to prevent bit deflection or breakage. Inspect the cutting edges for wear or chipping before each use, as small-diameter HSS bits are sensitive to overloading.
