Guhring 9026020032600 Jobber Drill Bit Size 30 Carbide

Product Description

The GUHRING 9026020032600 is a solid carbide jobber length drill bit designed for precision drilling in metalworking and machining applications. Built to ANSI standards, this Series 2602 bit features a 130-degree point angle, a parabolic flute geometry, and a titanium nitride (TiN) coating for extended tool life. The submicron carbide grade provides hardness and edge retention beyond standard HSS tooling. With an overall length of 2.75 inches and a flute length of 1.625 inches, it handles drilling depths up to 1.45 inches. It is installed and operated by machinists and CNC operators working on precision components.

This drill bit is sized at wire gauge number 30, with a decimal inch diameter of 0.1285 inches and a shank diameter of 0.1283 inches. The parabolic flute design promotes efficient chip evacuation during drilling. Primary workpiece material classifications include aluminum, non-ferrous materials, and general steels, corresponding to material codes K, N, and P. The straight-cylindrical shank fits standard drill chucks and collets. The 8xD flute-to-diameter ratio supports deeper drilling passes without sacrificing chip clearance.

Key Features

• Solid carbide submicron grade construction for high hardness and wear resistance
• TiN coating reduces friction and extends cutting edge life
• 130-degree point angle with web-thinned, tapered web for reduced entry force
• Parabolic flute geometry for improved chip evacuation in deep-hole drilling
• 8xD flute-to-diameter ratio supports drilling up to 1.45 inches deep
• Straight-cylindrical shank compatible with standard chucks and collets

Compatibility

Designed as an OEM-style precision drill bit for use in standard drill chucks and collets accepting a 0.1283-inch straight-cylindrical shank, suitable for CNC and manual drilling equipment operating on aluminum, non-ferrous, and general steel workpieces.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with carbide tooling. Secure the straight-cylindrical shank firmly in a compatible collet or drill chuck before operation to prevent runout. Carbide tooling is brittle compared to HSS — avoid side loading or impact that can chip the cutting edge. Confirm spindle speed and feed rate are appropriate for the workpiece material and bit diameter before beginning the cut.
