Guhring 9026010067500 Carbide Jobber Drill Bit Letter H

Product Description

The GUHRING 9026010067500 is a solid carbide jobber-length drill bit sized to Letter H (17/64 inch, 0.2657 inch decimal) with a 130-degree point angle and a parabolic flute geometry. It is built from submicron-grade solid carbide with a bright, uncoated finish and a web-thinned, tapered web for reduced thrust on entry. The straight-cylindrical shank measures 17/64 inch in diameter. Overall length is 4.125 inches, and flute length is 2.875 inches. Maximum drilling depth is 2.539 inches. This bit is part of the Guhring Series 2601 and is intended for use by machinists, tool-and-die professionals, and production drilling operations.

The 9026010067500 is optimized for drilling aluminum and other non-ferrous and some plastic or composite materials, consistent with its primary workpiece material codes K, N, and P. The parabolic flute design promotes fast chip evacuation, which is especially important in gummy or long-chip materials like aluminum. The 8xD flute-to-diameter ratio supports deeper drilling passes relative to the bit diameter. This bit suits job shop and production environments where a reliable, repeatable carbide jobber bit is required for hand-held or CNC drilling operations at standard jobber reach.

Key Features

• Submicron solid carbide construction for wear resistance in non-ferrous materials
• 130-degree split-point geometry reduces walking and lowers thrust force at entry
• Parabolic flute profile accelerates chip evacuation in aluminum and plastics
• Web-thinned, tapered web decreases cutting resistance and heat buildup
• Bright uncoated finish suitable for aluminum where coatings can cause built-up edge
• Straight-cylindrical shank compatible with standard drill chucks and collets

Compatibility

Designed as a direct-fit jobber-length drill bit for use in standard drill chucks and collets accepting a 17/64-inch straight-cylindrical shank. Meets ANSI standards for jobber-length drill bits in the 0.2500 to 0.3000 inch diameter range.

Installation Notes

Installation of this bit requires a drill chuck or collet rated for a 17/64-inch straight shank; ensure the chuck or collet is fully tightened and the machine spindle is at a complete stop before changing tooling. Machinists should verify spindle speed and feed rate are appropriate for solid carbide tooling in the workpiece material before cutting, as carbide is brittle and sensitive to shock loading. Coolant-through is not supported on this bit; use flood or mist coolant externally when required by the application. Dispose of worn carbide tooling in accordance with applicable shop waste guidelines.
