Guhring 9007300017000 Stub Drill Bit 0.067in Carbide 51

Product Description

The GUHRING 9007300017000 is a stub-length (screw machine length) solid carbide drill bit designed for precision drilling in small-diameter applications. Sized at 0.067 inches (Wire Size 51), it features a 118-degree faceted point angle and a right-hand spiral flute configuration. The micrograin solid carbide construction provides rigidity and edge retention well suited to tight-tolerance work. With a bright/uncoated finish and a straight-cylindrical shank, this bit is a general-purpose tool used by machinists, toolroom technicians, and trade professionals who require reliable performance in small-hole drilling operations. It conforms to DIN 6539 standards.

This drill bit is intended for general-purpose drilling, with aluminum listed as the primary workpiece material. Its stub-length body keeps deflection low in short-reach applications such as screw machine operations, fixture work, and precision assembly. The 3xD flute-to-diameter ratio and web-thinned point reduce entry resistance and help clear chips efficiently. It is sold individually and is suited for use in both CNC and manual drill press setups where small-diameter, high-accuracy holes are required.

Key Features

• Solid micrograin carbide construction for rigidity and extended edge life
• 118-degree faceted point angle with web thinning for clean entry and reduced thrust
• Stub (screw machine) length minimizes deflection in short-reach drilling
• Right-hand cut with regular spiral flute for efficient chip evacuation
• Bright/uncoated finish compatible with a range of cutting fluids
• Straight-cylindrical shank fits standard collets and drill chucks
• Conforms to DIN 6539 specification with h8 diameter tolerance

Compatibility

Designed as a general-purpose stub-length drill bit suitable for CNC machining centers, screw machines, and manual drill presses accepting a straight-cylindrical shank with a 1.70 mm shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with small-diameter carbide tooling. Secure the straight shank firmly in a compatible collet or drill chuck before operation to prevent runout. Carbide tooling is brittle - avoid side loading, interrupted cuts without appropriate feed rates, or dropping the bit. Always power down and lock out the machine before changing tooling.
