Guhring 9026020040900 Jobber Drill Bit No.20 Solid Carbide

Product Description

The GUHRING 9026020040900 is a jobber-length drill bit designed for precision drilling in demanding production environments. Built from submicron solid carbide and coated with titanium nitride (TiN), this bit holds tight tolerances and resists wear across extended run cycles. It measures 3.25 inches overall length with a 2.125-inch flute length, and cuts a No. 20 wire gauge hole at 0.1610 inches in diameter. The 130-degree point angle and parabolic flute geometry work together to evacuate chips efficiently and reduce heat buildup at the cutting edge. Licensed machinists and tooling technicians are the primary users of this series in CNC and manual drill press applications.

This bit is engineered primarily for aluminum and non-ferrous materials, consistent with its K, N, and P workpiece material codes. The parabolic flute design with an 8xD flute-to-diameter ratio supports deeper-than-standard drilling passes while maintaining chip clearance. It fits standard straight-cylindrical shank tool holders at 0.1610-inch shank diameter, making it compatible with common collet chucks and drill chucks found in production shops, job shops, and maintenance operations.

Key Features

• Submicron solid carbide construction for wear resistance and dimensional stability
• Titanium nitride (TiN) coating extends tool life and reduces friction in non-ferrous materials
• 130-degree point angle with web-thinned, tapered web for reduced thrust force at entry
• Parabolic flute geometry with 8xD ratio promotes efficient chip evacuation in deep-hole drilling
• Straight-cylindrical shank at 0.1610 inches fits standard collet and drill chuck setups
• Diameter tolerance of +0.000 to -0.018 mm supports close-tolerance hole requirements

Compatibility

Designed as an OEM-style production drill bit for use in straight-cylindrical shank tool holders; optimized for aluminum, non-ferrous, and plastic workpiece materials per ANSI Series 2602 specification.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or tooling technicians familiar with CNC machining centers or manual drill press setups. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the straight shank fully in the collet or drill chuck and verify runout before initiating a cut. Do not exceed the maximum recommended drilling depth of 1.92 inches without retracting to clear chips.
