Guhring 9006670011500 Taper Length Drill 0.0453 in Hss

Product Description

The GUHRING 9006670011500 is a taper length twist drill bit designed for precision drilling in metal fabrication, toolroom, and general machining applications. It measures 0.0453 inches (1.15 mm) in diameter with a 118-degree cone relief point angle and is manufactured from M2 high-speed steel (HSS) with a titanium nitride (TiN) coating for extended tool life. The right-hand spiral flute geometry and web-thinned point reduce entry force and improve chip evacuation. At 60 mm overall length with a 37 mm flute length, this drill fits standard straight-cylindrical collet chucks and drill press spindles. It carries a Series 667 designation and conforms to h8 diameter tolerance for consistent, repeatable hole sizing.

This drill bit is suited for small-diameter precision work in ferrous and non-ferrous metals, plastics, and composite materials. The taper length design provides additional reach compared to a jobber-length drill while maintaining rigidity for close-tolerance hole production. Typical applications include toolroom work, fixture building, and production drilling where tight diameter tolerance and finish quality are required. The 10xD flute-to-diameter ratio supports deeper drilling passes with adequate chip clearance. It is sold and packaged as a single unit.

Key Features

• M2 HSS construction provides hardness and wear resistance for metal drilling
• TiN coating reduces friction and extends cutting edge life compared to uncoated HSS
• 118-degree cone relief point with web thinning reduces thrust force at entry
• Right-hand cut, regular spiral flute promotes consistent chip evacuation
• h8 diameter tolerance ensures repeatable, close-tolerance hole sizing
• Straight-cylindrical shank fits standard collet chucks and drill press spindles

Compatibility

Designed as an OEM-style taper length drill for use in standard straight-cylindrical collet chucks, drill presses, and CNC machining centers accepting 1.15 mm shank diameters.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with small-diameter tooling. Ensure the spindle and chuck are fully powered down and secured before inserting or removing the bit. Use appropriate cutting fluid or coolant for the workpiece material to prevent premature edge wear. Do not exceed the recommended feed and speed parameters for the workpiece material and machine setup.
