Guhring 9026010040900 Solid Carbide Jobber Drill Bit No.20

Product Description

The GUHRING 9026010040900 is a solid carbide jobber-length drill bit designed for precision drilling in metalworking and machining applications. Built from submicron-grade solid carbide, it delivers consistent performance in materials including aluminum, non-ferrous metals, and plastics. The bit measures 3.25 inches overall with a 2.125-inch parabolic flute, a 130-degree point angle, and a bright uncoated finish. Right-hand cut geometry and a web-thinned, tapered web configuration reduce entry force and improve chip evacuation. The straight-cylindrical shank measures 0.1610 inches in diameter and seats directly in standard drill chucks and collets. This is a tool for machinists, tool-and-die professionals, and CNC operators working to ANSI standards.

This drill bit is sized at No. 20 wire gauge (0.1610 inches) and belongs to GUHRING Series 2601, which is engineered for an 8xD flute-to-diameter ratio. It is suited for drilling aluminum and non-ferrous workpieces in production and job-shop environments. The parabolic flute geometry promotes efficient chip flow during deeper passes, with a maximum drilling depth of 1.924 inches. Typical applications include component drilling on CNC machining centers, drill presses, and manual mills where tight tolerances and tool life consistency are required.

Key Features

• Submicron-grade solid carbide construction for extended tool life in non-ferrous and plastic workpieces
• 130-degree point angle reduces thrust force and improves hole entry accuracy
• Parabolic flute geometry promotes efficient chip evacuation at depth
• Web-thinned, tapered web lowers cutting resistance on entry
• Bright uncoated finish suitable for aluminum and non-ferrous materials
• Straight-cylindrical shank compatible with standard chucks and collets

Compatibility

Designed as a Series 2601 jobber-length drill bit for use in CNC machining centers, drill presses, and milling machines equipped with standard straight-shank chucks or collets accepting a 0.1610-inch shank. Suitable for primary workpiece material codes K, N, and P as designated in the product specifications.

Installation Notes

Installation and use of this tool should be performed by qualified machinists or toolroom personnel familiar with carbide tooling. Ensure the spindle and workholding are fully secured before operation, as carbide is brittle and sensitive to lateral shock or improper seating. Verify chuck or collet runout is within acceptable limits to avoid premature chipping of the cutting edge. Follow applicable shop safety protocols and machine manufacturer guidelines when setting speeds and feeds for the target workpiece material.
