Guhring 9026020034500 Carbide Drill Bit No. 29 Tin

Product Description

The GUHRING 9026020034500 is a solid carbide jobber-length drill bit in wire gauge size No. 29 (0.1358 inches), designed for precision drilling in metalworking and machining applications. Built on GUHRING Series 2602, it features a parabolic flute geometry and a titanium nitride (TiN) coating that extends tool life and reduces cutting friction. The 130-degree split point and web-thinned, tapered web configuration promote clean entry and reduce thrust in a wide range of materials. With an overall length of 73.03 mm and a flute length of 44.45 mm, this bit is suited for accurate, repeatable hole production in production shop environments.

This drill bit is rated for use in aluminum and non-ferrous metals, as indicated by workpiece material codes K, N, and P. It is a strong choice for CNC machining centers, drill presses, and hand-held pneumatic drills where consistent diameter tolerance is required. The straight-cylindrical shank seats cleanly in standard drill chucks and collets. Maximum drilling depth is 1.56 inches (39.73 mm), making it appropriate for jobber-length applications in light to medium material thicknesses. It is installed and used by machinists and tool-and-die professionals in production and job-shop settings.

Key Features

• Solid carbide submicron-grade construction for rigidity and wear resistance
• TiN (titanium nitride) coating reduces friction and extends cutting life
• Parabolic flute profile promotes efficient chip evacuation
• 130-degree point angle with web thinning reduces entry thrust and walking
• Straight-cylindrical shank compatible with standard chucks and collets
• Tight diameter tolerance of +0.000 to -0.018 mm for accurate hole sizing

Compatibility

Designed for use in aluminum and compatible non-ferrous and ferrous workpiece materials (material codes K, N, P). Fits standard drill chucks and collets accepting a 0.1358-inch straight-cylindrical shank. Conforms to ANSI specification designation for jobber-length drill bits.

Installation Notes

This bit is installed by machinists in CNC machining centers, drill presses, or pneumatic drill equipment. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully and evenly in the chuck or collet to prevent runout. Use appropriate cutting fluid or mist lubrication when drilling ferrous or hard non-ferrous materials to preserve coating life.
