Guhring 9005350010700 Taper Length Drill Bit 0.0421 in

Product Description

The GUHRING 9005350010700 is a taper length twist drill bit designed for precision drilling in metalworking and machining applications. Built to DIN 340 specification from high-speed steel (HSS), this Series 535 bit features a 130-degree split point angle and a parabolic flute geometry that promotes faster chip evacuation and reduced heat buildup compared to standard flute designs. With a 0.0421-inch diameter and a bright, uncoated finish, it is well-suited for use where coating is not required or where baseline performance is the priority. Licensed machinists and tool-and-die professionals are the primary installers of this type of tooling.

This drill bit is appropriate for use on aluminum alloy, cast iron, and steel workpieces. The taper length body gives greater reach than a jobber-length bit while maintaining rigidity for accurate hole entry. The straight shank allows it to seat directly in standard drill chucks and collet holders without adapters. It is a high-performance grade bit intended for production environments and precision shop floor operations where consistent hole quality and tight tolerance control are required. The parabolic flute and web-thinned point reduce thrust and walking at hole entry.

Key Features

• 130-degree standard point angle for reduced thrust and clean entry on metal workpieces
• Parabolic flute design accelerates chip removal and reduces chip packing in deep holes
• Web-thinned, parallel web construction lowers cutting resistance at the point
• High-speed steel construction provides toughness across aluminum alloy, cast iron, and steel
• Bright/uncoated finish — no coating buildup to affect diameter tolerance in precision applications
• Conforms to DIN 340 specification for consistent geometry and interchangeability

Compatibility

Designed for use in materials including aluminum alloy, cast iron, and steel, as stated by the manufacturer for Series 535. Fits standard drill chucks and collet systems that accept a 0.0421-inch straight shank diameter.

Installation Notes

This bit is installed by machinists and tooling professionals in drill presses, CNC machining centers, or hand-held power drills equipped with a compatible chuck or collet. Ensure the workpiece is securely clamped and the machine spindle is fully stopped before changing tooling. Verify shank seating and chuck tightness before initiating a cut. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, even though coolant-through is not supported by this bit.
