Guhring 9005350127000 Taper Length Drill Bit 1/2 Inch Hss

Product Description

The GUHRING 9005350127000 is a taper length twist drill bit built to Series 535 specifications per DIN 340. It features a 1/2 inch diameter with a matching 1/2 inch straight cylindrical shank, a 130-degree standard point, and a parabolic flute geometry with web thinning for improved chip evacuation and reduced thrust. The bit is manufactured from high-speed steel (HSS) with a bright uncoated finish, making it well suited for high-performance drilling applications where dimensional accuracy and flute clearance are priorities. Licensed machinists, tool-and-die shops, and production drilling operations are the primary users of this type of bit.

This drill bit is designed for use in stationary drill presses, milling machines, and CNC machining centers. The taper length body provides greater reach than jobber-length bits without sacrificing rigidity, making it appropriate for deeper hole drilling in production environments. Per GUHRING Series 535 specifications, this bit is rated for use in aluminum alloy, cast iron, and steel. The parabolic flute profile promotes fast chip removal, which is especially valuable in interrupted cuts and through-hole operations in these materials.

Key Features

• 1/2 inch diameter with 130-degree standard point for clean entry in ferrous and non-ferrous materials
• Parabolic flute with web thinning reduces cutting resistance and improves chip flow
• Taper length body at 8-1/16 inches OAL provides extended reach versus standard jobber bits
• High-speed steel construction rated for aluminum alloy, cast iron, and steel applications
• Straight cylindrical shank fits standard drill chucks and collet systems without adapters
• Bright uncoated finish suitable for use with cutting fluids; no coating delamination risk

Compatibility

Rated for drilling aluminum alloy, cast iron, and steel per GUHRING Series 535 performance specifications. Fits any drill chuck or collet accepting a 1/2 inch straight shank.

Installation Notes

Installation and operation should be performed by qualified machinists or tooling professionals familiar with rotating cutting tools. Ensure the machine spindle is fully stopped and the chuck is securely tightened before beginning any drilling operation. Use an appropriate cutting fluid for the workpiece material to extend tool life and maintain dimensional accuracy. Inspect the cutting edges for wear or damage before each use; a chipped or dull point increases thrust load and can damage the workpiece or the machine spindle.
