Guhring 9026010051100 Carbide Jobber Drill Bit No.7

Product Description

The GUHRING 9026010051100 is a solid carbide jobber-length drill bit in No. 7 wire size (0.2012 inches diameter), built for precision drilling in aluminum and non-ferrous materials. The 130-degree split point with web thinning reduces thrust and improves centering on entry without a center punch. A parabolic flute geometry evacuates chips aggressively through the full 2.438-inch flute length. Submicron carbide grade delivers edge retention in abrasive materials where high-speed steel would degrade quickly. The bright uncoated finish suits applications where coating adhesion or chemical interaction is a concern. Installed by machinists and tool-and-die professionals in production and maintenance environments.

This bit is suited for drilling aluminum, plastics, and other non-ferrous workpiece materials in both CNC and manual drill press setups. The straight-cylindrical shank accommodates standard drill chucks and collet holders without modification. With an 8xD flute-to-diameter ratio and a maximum drilling depth of 2.187 inches, it handles typical jobber-range through-hole and blind-hole operations. GUHRING Series 2601 bits are used in light manufacturing, aerospace component work, and general machine shop production where dimensional accuracy and clean exit holes are required.

Key Features

• No. 7 wire size — 0.2012 inch diameter, diameter tolerance +0.000 to -0.018 mm
• 130-degree point angle with web thinning for reduced entry thrust and accurate self-centering
• Parabolic flute design for fast chip evacuation in deep-hole and through-hole drilling
• Submicron solid carbide construction for extended tool life in abrasive non-ferrous materials
• Bright uncoated finish — compatible with coolant and dry cutting environments
• Straight-cylindrical shank fits standard chucks and collet systems; ANSI standard compliance

Compatibility

Designed for drilling aluminum, plastics, and non-ferrous materials (material codes K, N, P). Fits standard drill chucks and collet holders accepting a 0.2012-inch straight-cylindrical shank. Conforms to ANSI standards for jobber-length drill bits in the 0.2000 to 0.2500 inch diameter range.

Installation Notes

Install in a properly rated drill chuck or collet holder, ensuring full shank engagement before operation. Confirm spindle speed and feed rate are appropriate for carbide tooling in the target material — carbide requires rigid setups with minimal runout to avoid chipping the cutting edge. Do not use this bit in hammer-drill mode. Inspect the cutting edge before each use; carbide is hard but brittle and should be handled to avoid impact damage during storage and setup.
