Guhring 9005300017000 Jobber Drill Bit 51 Firex Pm

Product Description

The GUHRING 9005300017000 is a jobber-length drill bit manufactured from Powdered Metal (PM-ASP-60) and finished with a FIREX coating for extended tool life in demanding applications. Sized to wire gauge 51 (0.0669 inches decimal), it features a 130-degree drill point angle with cone relief geometry and a parabolic flute profile that improves chip evacuation and reduces heat buildup. The straight-cylindrical shank measures 0.0669 inches in diameter, and the overall length is 1-11/16 inches. Right-hand cutting direction. Two flutes. This bit is built to DIN 338 standards and is intended for use by machinists and industrial trades requiring consistent, high-performance small-diameter drilling.

Designed for drilling cast iron and steel, this bit fits production, maintenance, and toolroom applications where small-diameter precision is critical. The parabolic flute geometry supports a 5xD flute-to-diameter ratio, allowing a maximum drilling depth of 0.687 inches. The FIREX coating reduces friction and improves wear resistance on ferrous materials. It is suited for CNC machining centers, drill presses, and handheld power tools used in metal fabrication and manufacturing environments where wire-gauge sizing is specified.

Key Features

• Wire gauge size 51, 0.0669 inches decimal — fits precise small-diameter applications in ferrous metals
• FIREX coating reduces friction and extends tool life on cast iron and steel
• Parabolic flute design at 5xD ratio improves chip evacuation and reduces heat at depth
• 130-degree drill point angle with cone relief for accurate positioning and reduced thrust
• Web-thinned, tapered web configuration for easier penetration and reduced cutting force
• Manufactured to DIN 338 standards from PM-ASP-60 powdered metal for high-performance cutting

Compatibility

Designed as a DIN 338 jobber-length drill bit for use in cast iron and steel workpieces. Compatible with any standard straight-shank drill chuck accepting a 0.0669-inch shank diameter.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or trade professionals familiar with small-diameter drilling practices. Ensure the drill chuck is fully tightened and the workpiece is securely fixtured before beginning. Power down the machine and release all stored energy before changing tooling. Do not exceed the rated maximum drilling depth of 0.687 inches without retracting to clear chips.
