Guhring 9026010048500 Carbide Jobber Drill Bit No. 11

Product Description

The GUHRING 9026010048500 is a solid carbide jobber-length drill bit in wire gauge size No. 11, equal to 0.1909 inches in decimal. It features a 130-degree split point, parabolic flute geometry, and a bright uncoated finish. The straight-cylindrical shank measures 0.1909 inches in diameter and seats directly into standard drill chucks and collet holders. At 3.5 inches overall length with a flute length of 2.313 inches and a maximum drilling depth of 2.08 inches, this bit is built for production and job-shop drilling applications where dimensional accuracy and chip evacuation matter. It is sized within the ANSI specification range and manufactured from submicron-grade carbide for edge stability at higher feed rates.

This bit is engineered for drilling aluminum, non-ferrous metals, and plastics, as indicated by primary workpiece material codes K, N, and P. The parabolic flute design at an 8xD flute-to-diameter ratio promotes fast chip removal in through-hole and deep-hole applications. The web-thinned, tapered-web point reduces thrust requirements on entry, making it well suited for CNC machining centers, drill presses, and manual operations requiring tight-tolerance hole sizing in light-alloy and thermoplastic components. It ships as a single unit and is sourced from GUHRING Series 2601.

Key Features

• Submicron solid carbide construction for edge retention and dimensional stability
• 130-degree standard point with web thinning reduces entry thrust and improves centering
• Parabolic flute geometry at 8xD ratio accelerates chip evacuation in deep holes
• Bright uncoated finish suits aluminum, non-ferrous, and plastic workpiece materials
• Diameter tolerance held to +0.000 to -0.018 mm for consistent hole sizing
• Straight-cylindrical shank compatible with standard drill chucks and collet systems

Compatibility

Designed for use in CNC machining centers, drill presses, and handheld drilling equipment accepting a straight-cylindrical shank. Primary workpiece materials are aluminum, non-ferrous metals, and plastics per material codes K, N, and P. Conforms to ANSI standards for jobber-length drill bits in the 0.1500 to 0.2000 inch diameter range.

Installation Notes

Installation is performed by machinists and tool-and-die or CNC setup technicians. Secure the shank fully in the chuck or collet before operation and verify runout with a dial indicator when tolerances are critical. Power down and de-energize the machine spindle before changing tooling. Do not exceed the recommended maximum drilling depth of 2.08 inches without retracting to clear chips.
