Guhring 9026020040000 Carbide Drill Bit 4mm Tin

Product Description

The GUHRING 9026020040000 is a solid carbide jobber-length drill bit designed for high-performance drilling in non-ferrous metals, aluminum, and general-purpose materials. Built to Series 2602 specifications, this bit features a 130-degree split point, a parabolic flute geometry, and a titanium nitride (TiN) coating for extended tool life. The overall length is 82.55 mm (approximately 3.25 inches), with a 2-flute, right-hand cut configuration and a straight-cylindrical shank. It is suited for use by machinists, tool-and-die technicians, and maintenance professionals working with CNC machines, drill presses, and manual lathes.

This drill bit is rated for primary use in aluminum and other non-ferrous and non-metallic workpiece materials, consistent with material codes K, N, and P. The parabolic flute design promotes efficient chip evacuation at higher feed rates, making it a practical choice for production drilling environments. Maximum drilling depth is 49 mm (approximately 1.93 inches). The bit does not include coolant-through capability, so external coolant or cutting fluid should be applied as needed for heat management during extended cuts.

Key Features

• Submicron solid carbide construction for hardness and wear resistance
• TiN coating reduces friction and extends cutting edge life
• 130-degree point angle with web-thinned, tapered web for reduced thrust force
• Parabolic flute geometry promotes fast, clean chip evacuation
• Right-hand cut, straight-cylindrical shank compatible with standard drill chucks and collets
• Diameter tolerance held to +0.000 to -0.018 mm for precise hole sizing

Compatibility

Designed for use in drilling aluminum, non-ferrous metals, and plastics (material codes K, N, P) on CNC machining centers, drill presses, and similar equipment accepting a 4 mm straight-cylindrical shank. Part of the GUHRING Series 2602 drill bit family, sized within the 4.00 to 5.00 mm diameter range grouping.

Installation Notes

This drill bit is installed and serviced by qualified machinists or tooling technicians. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Secure the straight-cylindrical shank firmly in a drill chuck or collet to the manufacturer-recommended clamping depth before operation. Because this bit does not have coolant-through capability, apply appropriate external cutting fluid to manage heat when drilling at higher speeds or feed rates.
