Guhring 9006580010700 Cobalt Drill Bit Wire 58 Tin

Product Description

The GUHRING 9006580010700 is a cobalt jobber length drill bit designed for high-performance drilling in demanding metalworking applications. Sized to wire gauge 58 (0.0421 inches decimal), this bit features a 130-degree split point, a parabolic flute geometry, and a titanium nitride (TiN) coating. The TiN coating reduces friction and extends tool life when cutting through abrasive materials. Overall length is 1-7/16 inches with a straight-cylindrical shank. The parabolic flute profile improves chip evacuation, reducing heat buildup during deep drilling cycles. This bit is intended for use by machinists, toolroom technicians, and production drilling professionals working with tight-tolerance hole requirements.

This drill bit is suited for drilling cast iron and steel in both production and maintenance environments. The DIN 338 standard geometry makes it a direct fit for standard drill chucks and CNC machining centers. The 130-degree point angle reduces thrust force on entry and is well matched to hard ferrous materials. With a maximum drilling depth of 0.488 inches (12.40 mm) and a flute-to-diameter ratio of 5xD, it handles through-holes and blind holes in typical sheet and plate stock. The web-thinned, tapered web configuration reduces the chisel edge and improves centering without a separate spotting operation.

Key Features

• Wire size 58, 0.0421-inch decimal diameter with a diameter tolerance of -0.014 to 0.000 mm for consistent hole sizing
• Cobalt high-speed steel construction for elevated heat resistance in ferrous and hard metal drilling
• Titanium nitride (TiN) coating reduces surface friction and improves wear resistance
• Parabolic flute design promotes efficient chip evacuation and reduced heat buildup
• 130-degree standard point angle with web thinning for reduced entry thrust and improved centering
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Meets DIN 338 specification for jobber length geometry

Compatibility

Designed as an OEM-spec replacement or new-stock drill bit conforming to DIN 338 jobber length standards, compatible with standard straight-shank drill chucks and collet systems accepting a 0.0421-inch shank diameter. Rated for primary workpiece materials cast iron and steel per material codes K and P.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or toolroom technicians familiar with cutting tool setup and machine operation. Ensure the drill chuck or collet is clean and properly torqued before operation, and confirm spindle speed is set per manufacturer recommendations for the workpiece material and bit diameter. Do not exceed the maximum drilling depth of 0.488 inches without retracting to clear chips. Coolant-through is not supported on this bit; apply flood or mist coolant externally if required by the workpiece material.
