Guhring 9024630027800 7/64 Stub Carbide Drill Bit

Product Description

The GUHRING 9024630027800 is a stub-length (screw machine length) solid carbide drill bit designed for precision drilling in production and machining environments. Built to DIN 6539 standards, it features a 118-degree faceted drill point and a web-thinned tip that reduces thrust and improves chip evacuation. At 0.1094 inches (7/64 inch) in diameter with a 1.811-inch overall length and a 0.63-inch spiral flute, this bit is compact and rigid — well suited for short-reach drilling operations where runout control and hole accuracy are critical. Solid carbide construction from K40 material grade delivers the hardness and wear resistance needed for consistent performance in metalworking and industrial applications.

This drill bit is primarily intended for drilling aluminum and similar non-ferrous materials, though its general-purpose tool performance rating makes it applicable across a range of workpiece materials. The straight-cylindrical shank fits standard drill chucks and collet-style toolholders used in CNC machining centers, drill presses, and screw machine setups. The 3xD flute-to-diameter ratio and 11.83 mm maximum drilling depth make it appropriate for shallow-hole applications in precision part production. It is typically installed and used by machinists, toolroom technicians, and CNC operators in manufacturing and job-shop environments.

Key Features

• Solid carbide K40 material grade for wear resistance and rigidity
• 118-degree faceted drill point with web thinning for reduced entry thrust
• DIN 6539 standard construction for dimensional consistency
• 2-flute regular spiral design promotes chip clearance in short-hole drilling
• Straight-cylindrical shank for compatibility with standard chucks and collets
• Coated finish for added surface protection and tool life

Compatibility

Designed as a DIN 6539 Series 2463 stub-length carbide drill bit suitable for use in CNC machining centers, drill presses, and screw machine setups with standard straight-shank toolholding systems accepting a 2.78 mm shank diameter.

Installation Notes

This drill bit is installed and operated by machinists and CNC technicians. Before changing or setting tooling, ensure the machine is fully powered down and spindle rotation has stopped. Secure the straight-cylindrical shank firmly in a compatible collet or drill chuck to the toolholder manufacturer's specified clamping procedure. Do not exceed the maximum drilling depth of 0.466 inches per pass without confirming chip clearance to avoid bit deflection or breakage in carbide tooling.
