Guhring 9026010053100 Carbide Jobber Drill Bit No. 4

Product Description

The GUHRING 9026010053100 is a solid carbide jobber-length drill bit designed for precision hole-making in demanding production environments. Built to ANSI standards, this Series 2601 bit features a 130-degree point angle and a parabolic flute geometry that promotes efficient chip evacuation. The submicron carbide substrate provides the hardness and wear resistance required for consistent performance in high-volume drilling operations. At 3.75 inches overall length with a 2.5-inch flute, it delivers the reach needed for standard jobber applications. The bright uncoated finish suits applications where coating-induced dimensional changes are a concern. Licensed machinists and precision toolroom technicians are the primary installers of this bit type.

This bit is rated for drilling aluminum as its primary workpiece material, with material codes K, N, and P indicating suitability across non-ferrous metals and certain plastic and composite materials. The No. 4 wire gauge size corresponds to 0.2091 inches in decimal inch. Straight-cylindrical shank diameter matches the bit diameter at 0.2091 inches, making it compatible with standard drill chucks and collet systems. The 8xD flute-to-diameter ratio supports a maximum drilling depth of 2.254 inches. The parabolic flute profile reduces friction and heat buildup during extended cuts in soft to medium-hardness materials.

Key Features

• Solid carbide submicron-grade substrate for enhanced hardness and tool life
• 130-degree split point reduces walking and lowers thrust requirements at entry
• Parabolic flute geometry accelerates chip clearance in deep-hole applications
• Web-thinned, tapered web construction reduces cutting resistance
• Bright uncoated finish maintains tight dimensional tolerance: +0.000 to -0.018 mm
• ANSI-compliant Series 2601 design for consistent interchangeability

Compatibility

Designed for use in standard drill chucks and precision collet systems accepting a 0.2091-inch straight-cylindrical shank. Suited primarily for drilling aluminum and comparable non-ferrous materials in CNC and manual drill press applications.

Installation Notes

Installation and operation of this bit should be performed by qualified machinists or toolroom technicians familiar with proper cutting speeds and feeds for solid carbide tooling. Ensure the spindle and chuck are fully de-energized and at a complete stop before inserting or removing the bit. Solid carbide is brittle relative to high-speed steel; avoid side-loading or using in impact-type drivers. Verify chuck runout is within acceptable limits before use to prevent premature bit failure or oversized holes.
