Guhring 9026020069000 Drill Bit Letter I Solid Carbide

Product Description

The GUHRING 9026020069000 is a jobber-length drill bit sized to letter I (0.2717 inches) with a 130-degree split point and a titanium nitride (TiN) coating over a solid submicron carbide body. The parabolic flute geometry promotes efficient chip evacuation and reduced heat buildup at the cutting edge. With a straight-cylindrical shank and web-thinned, tapered web design, this bit is built for precision hole-making in demanding materials. It is sized to ANSI specification and suited for machinists, toolroom technicians, and maintenance trades that require tight-tolerance drilling in production or repair environments.

This drill bit fits typical jobber-length applications in metalworking, maintenance, and fabrication settings. The 0.2717-inch diameter places it in the 0.2500 to 0.3000-inch size range, making it a common choice for tapping pre-drill operations, close-tolerance bores, and general-purpose through-hole work in ferrous and non-ferrous materials. It is compatible with standard drill chucks and collet holders that accept a 0.2717-inch straight shank. Each unit is sold individually.

Key Features

• Solid submicron carbide construction for extended tool life in abrasive and hard materials
• TiN coating reduces friction and improves wear resistance at the cutting edge
• Parabolic flute design promotes fast chip evacuation and reduces recutting
• 130-degree point angle with web thinning improves self-centering and reduces thrust force
• Straight-cylindrical shank fits standard drill chucks and collet holders
• ANSI-specification sizing ensures dimensional consistency across tool changes

Compatibility

Designed for use in standard drill chucks and collet systems accepting a 0.2717-inch straight-cylindrical shank. Fits within the 0.2500 to 0.3000-inch drill bit size range per ANSI specification.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel familiar with carbide tooling. Secure the shank fully in the chuck or collet before operation and verify runout before drilling. Carbide tooling is brittle — avoid side-loading, interrupted cuts without appropriate feed rate adjustment, and contact with hard inclusions that exceed the tool rating. Power down and de-energize the machine spindle completely before changing tooling.
