Guhring 9006520017000 Jobber Drill Bit 51 Hss Tin

Product Description

The GUHRING 9006520017000 is a jobber-length twist drill bit sized to wire gauge No. 51, with a decimal diameter of 0.0669 inches. It is manufactured from high-speed steel (HSS) with a titanium nitride (TiN) coating to reduce friction and extend cutting life. The 130-degree split point combined with a parabolic flute geometry improves chip evacuation and reduces thrust force during drilling. The overall length is 1-11/16 inches with a flute length of 25/32 inches. This bit is intended for professional use by machinists, maintenance technicians, and tradespeople requiring precise small-diameter drilling in production or field environments.

This drill bit is rated for primary use in aluminum and other non-ferrous and general-purpose materials, reflected by its K, N, and P workpiece material codes per DIN 338 classification. It is well suited for precision hole-making in sheet metal, light structural components, and mechanical assemblies where a No. 51 wire gauge hole is specified. The straight-cylindrical shank fits standard drill chucks without adapters. The parabolic flute and web-thinned point make this bit particularly effective in high-cycle or production drilling applications where chip buildup is a concern.

Key Features

• Wire gauge No. 51 diameter — 0.0669 inches decimal equivalent
• 130-degree standard point angle with web-thinned, tapered web configuration
• Parabolic flute design for improved chip evacuation — flute-to-diameter ratio of 5xD
• Titanium nitride (TiN) coating for reduced friction and improved tool life
• Right-hand cut with straight-cylindrical shank — 0.0669 inches shank diameter
• Conforms to DIN 338 specification — High Performance grade

Compatibility

Designed as an OEM-style jobber-length drill bit conforming to DIN 338 standards, suitable for use in standard drill chucks and CNC drilling applications requiring a No. 51 wire gauge diameter.

Installation Notes

Installation of this bit is performed by machinists and maintenance professionals using standard keyed or keyless drill chucks. Before changing bits, ensure the drill press, hand drill, or CNC spindle is fully powered down and secured. Verify chuck capacity accommodates the 0.0669-inch shank diameter prior to use. Do not exceed the maximum drilling depth of 0.687 inches without retracting to clear chips, particularly when drilling aluminum or other gummy materials.
