Guhring 9003170100000 Taper Length Drill Bit 10mm

Product Description

The GUHRING 9003170100000 is a taper length twist drill bit from the Series 317 line, manufactured from M35 grade HSS-E cobalt steel. It is designed for drilling operations that require a longer flute-to-diameter ratio than a jobber drill, giving the tool greater reach in deeper-hole applications. The bit measures 10 mm in diameter with a 118-degree cone relief point and a spiral flute ground in a right-hand cutting direction. The shank is straight-cylindrical with a diameter tolerance of h8, making it compatible with standard drill chucks and collet holders. A web-thinned point geometry reduces thrust force at the start of cut.

This drill bit is suited for use in metalworking applications including structural steel, alloy steel, and stainless steel where cobalt tooling is required to manage heat buildup. The 10xD flute-to-diameter ratio makes it appropriate for through-hole and deeper blind-hole operations in machine shop, maintenance, and fabrication environments. It is installed in drill presses, CNC machining centers, and hand-held power tools by machinists and tool-and-die technicians. The bright, uncoated finish is typical for re-grinding and reconditioning applications.

Key Features

• M35 HSS-E cobalt steel construction resists heat buildup in tough materials
• 118-degree cone relief point with web thinning reduces entry thrust
• 10xD flute-to-diameter ratio provides extended reach for deeper holes
• Straight-cylindrical shank with h8 diameter tolerance for precise chuck fitment
• Right-hand spiral flute for standard drilling direction
• Bright, uncoated finish allows for easy visual inspection and re-sharpening

Compatibility

Designed as an OEM-style taper length drill bit for use in standard drill chucks and collet systems accepting a 10 mm straight-cylindrical shank.

Installation Notes

Installation and use of this tool should be performed by a qualified machinist or skilled tradesperson familiar with cutting tool setup and machine operation. Ensure the machine spindle is fully stopped and power is isolated before changing tooling. Secure the shank fully within the chuck or collet to the manufacturer-specified engagement depth to prevent pullout under load. Do not exceed the recommended feed and speed parameters for the workpiece material and tool diameter.
