Guhring 9007300026000 Carbide Stub Drill Bit 0.1024 in

Product Description

The GUHRING 9007300026000 is a solid micrograin carbide stub-length (screw machine length) drill bit designed for precision drilling in production and machining environments. Sized at 0.1024 inches (2.60 mm) in diameter, it features a 118-degree faceted point angle and a right-hand spiral flute geometry with web thinning to reduce thrust and improve chip evacuation. The straight-cylindrical shank conforms to DIN 6539 standards and is held to an h8 diameter tolerance, making it suitable for high-repeatability toolholding in CNC and manual drilling setups. Machinists and toolroom technicians are the primary installers of this bit.

This drill bit is rated for general-purpose drilling and is listed with aluminum as the primary workpiece material, though its micrograin carbide construction handles a range of non-ferrous and ferrous materials in light-to-moderate duty applications. The stub-length body with a 3xD flute-to-diameter ratio suits applications where rigidity is critical and overhang must be minimized, such as close-tolerance hole drilling on machining centers, drill presses, and CNC lathes. The overall length of 43.00 mm and flute length of 14.00 mm keep the bit compact and stiff in the cut.

Key Features

• Solid micrograin carbide construction for wear resistance and edge retention
• 118-degree faceted point with web thinning for reduced entry thrust
• Right-hand spiral flute, 2-flute design for efficient chip clearance
• Straight-cylindrical shank to DIN 6539, h8 tolerance for accurate toolholder fit
• Stub length (3xD) body maximizes rigidity and minimizes deflection
• Bright/uncoated finish, no coolant-through — suited for light-duty general purpose use

Compatibility

Designed as a general-purpose OEM-style stub drill for use in standard straight-shank drill chucks and collet holders accepting a 2.60 mm shank diameter, conforming to DIN 6539 specifications.

Installation Notes

This drill bit is installed and changed by machinists and toolroom technicians. Ensure the machine spindle is fully stopped and the tool is secured in a properly sized collet or drill chuck before beginning any setup. Carbide tooling is brittle — avoid side loading or using the bit as a reamer. Confirm runout is within acceptable limits at the toolholder before cutting to prevent premature chipping of the carbide edge.
