Guhring 9007300027100 Carbide Stub Drill Bit 0.1065 in

Product Description

The GUHRING 9007300027100 is a screw machine length (stub) solid carbide drill bit designed for precision drilling in tight-reach and high-production applications. Built to DIN 6539 standards, this Series 730 bit has a 0.1065-inch diameter, a 118-degree faceted point angle, and a web-thinned tip geometry that reduces entry thrust and improves chip ejection. The micrograin carbide construction delivers consistent edge retention at higher feed rates compared to high-speed steel alternatives. It carries a diameter tolerance of h8, making it suitable where hole accuracy matters. Machinists, tool-and-die techs, and CNC operators are the primary users.

This bit is rated for general-purpose drilling with a primary workpiece material of aluminum, and its 3xD flute-to-diameter ratio suits shallow-to-moderate depth holes. The maximum drilling depth is 0.47 inches (11.94 mm), and the overall length is approximately 46 mm with a 2.71 mm straight-cylindrical shank. The regular spiral flute and bright uncoated finish make it easy to inspect for wear and compatible with most standard collet and drill chuck setups. Right-hand cut only.

Key Features

• Solid micrograin carbide construction for extended tool life in non-ferrous and general-purpose materials
• 118-degree faceted point angle with web thinning for reduced entry thrust and accurate hole starts
• DIN 6539 specification, Series 730, diameter tolerance h8
• Bright/uncoated finish — no coating to obscure wear indicators
• Straight-cylindrical shank fits standard collets and drill chucks accepting 2.71 mm shank diameter
• Maximum drilling depth 0.47 inches; stub length for rigid, low-deflection setups

Compatibility

Designed as an OEM-style general-purpose stub drill bit per DIN 6539; compatible with any machine spindle or drill chuck accepting a straight-cylindrical 2.71 mm shank. Optimized for aluminum as primary workpiece material; suitable for other non-ferrous and general-purpose applications within the 0.1000 to 0.1500-inch drill diameter range of the Series 730 line.

Installation Notes

Installation is performed by machinists or CNC operators in a machine shop environment. Ensure the spindle and any connected equipment is fully powered down and locked out before changing tooling. Seat the shank fully and evenly in the collet or chuck and verify runout before cutting. Do not exceed the rated maximum drilling depth of 0.47 inches without retracting to clear chips.
