Precision Twist Drill 6000303 Jobber Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000303 is a jobber length drill bit engineered for precision drilling in demanding trade and industrial applications. Sized at 0.0079 inches in diameter with an overall length of 0.748 inches (19 mm), this bit is built from high speed steel with a bright uncoated finish. It features a standard 118-degree drill point angle, a two-flute regular spiral design, and a straight-cylindrical shank. The web-thinned, tapered web configuration reduces thrust during entry and helps maintain accuracy at this very small diameter. It is suited for use by machinists, maintenance technicians, and tool-and-die professionals.

This drill bit is designed for general-purpose drilling across a wide range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. Its 12xD flute-to-diameter ratio supports controlled chip evacuation in deep-hole applications relative to bit size. The 0.0984-inch flute length and 0.0984-inch maximum drilling depth make it appropriate for shallow, precise holes in tight-tolerance work. It conforms to DIN 338 specification, Series 2A, making it a recognized standard in industrial tooling inventories.

Key Features

• 0.0079-inch diameter with matching straight-cylindrical shank for precision fitment in small collets and chucks
• 118-degree standard point angle suits general-purpose drilling across multiple material types
• High speed steel construction provides durability in steel, stainless steel, cast iron, and non-ferrous metals
• Two-flute regular spiral with web-thinned tapered web reduces entry thrust at micro diameters
• Conforms to DIN 338 specification, Series 2A for consistent dimensional standards
• Right-hand cut, bright uncoated finish — no coolant-through required

Compatibility

Designed as a general-purpose jobber length drill bit conforming to DIN 338 standards, suitable for use in standard drill chucks, collets, and CNC toolholders accepting a 0.0079-inch straight-cylindrical shank.

Installation Notes

This bit should be installed by qualified machinists or technicians familiar with micro-diameter tooling. Secure the shank fully in the chuck or collet before operation and verify runout before drilling to prevent breakage at this diameter. Power down all equipment before changing bits. Avoid excessive feed pressure — micro drill bits are susceptible to breakage under lateral load or improper feed rates.
