Guhring 9024630010200 Stub Drill Bit 0.040 in Carbide

Product Description

The GUHRING 9024630010200 is a stub-length (screw machine length) solid carbide twist drill bit designed for precision small-diameter hole making in production and maintenance environments. Built to DIN 6539 standards, it carries a 0.040-inch (1.02 mm) diameter with a 118-degree faceted point angle and a web-thinned tip geometry that reduces thrust load on entry. The two-flute spiral design handles chip evacuation in short, controlled cuts. At 1.024 inches overall length with a 0.236-inch flute length, this bit is sized for CNC drill presses, screw machines, and benchtop drill fixtures where stub rigidity is required.

This drill bit is rated as a general-purpose tool with a primary workpiece material designation of aluminum, though its solid carbide construction handles a range of non-ferrous and engineered materials at high spindle speeds. The straight-cylindrical shank and compact stub-length body reduce deflection in tight setups. Maximum drilling depth is 0.176 inches (4.47 mm), making it well suited for shallow, high-precision through-holes and spotting operations in production settings. Machinists, tool-and-die technicians, and CNC operators in job shop or automated manufacturing environments are the typical end users.

Key Features

• Solid carbide construction per DIN 6539 for dimensional consistency and wear resistance
• 118-degree faceted point with web-thinned tip reduces entry thrust and improves centering
• Stub-length body minimizes deflection on small-diameter cuts
• Two-flute regular spiral design promotes chip clearance in shallow holes
• Straight-cylindrical shank fits standard collets and drill chucks without adapters
• Coated finish for extended tool life in general-purpose applications

Compatibility

Designed as an OEM-style production drill for use in standard collet chucks and drill fixtures that accept a 1.02 mm straight-cylindrical shank, consistent with DIN 6539 Series 2463 tooling specifications.

Installation Notes

Installation and use should be performed by qualified machinists or CNC technicians familiar with small-diameter carbide tooling. Secure the shank fully in a collet or drill chuck rated for the spindle RPM required by the workpiece material. Carbide drill bits are brittle — avoid side loading, interrupted cuts without proper feed reduction, or re-chucking on a worn or out-of-true spindle. Power down and lock out the machine before changing tooling.
