Guhring 9024630039100 Carbide Stub Drill Bit 0.154 in

Product Description

The GUHRING 9024630039100 is a stub-length screw machine drill bit designed for precision drilling in production and maintenance environments. Built from solid carbide grade K40, this bit delivers the rigidity and wear resistance needed when drilling aluminum and similar non-ferrous materials at high feed rates. The 118-degree faceted point angle and web-thinned geometry reduce entry thrust and improve hole quality. With a 0.154-inch diameter (wire size 23) and a 2-flute spiral flute design, this bit suits CNC machining centers, drill presses, and screw machines where compact tool length and runout control matter.

This bit is suited for production drilling in light manufacturing, aerospace fabrication, and machine shops working with aluminum as the primary workpiece material. The stub flute length and straight-cylindrical shank make it compatible with standard drill chucks and collet systems. It conforms to DIN 6539 standards with a DIN specification designation, making it a fit for shops that source to European tooling standards. General-purpose performance classification means it covers a wide range of production drilling tasks at the 0.15-inch to 0.20-inch diameter range.

Key Features

• Solid carbide K40 grade construction for rigidity and extended tool life in non-ferrous materials
• Web-thinned faceted point reduces entry thrust and improves centering accuracy
• 118-degree drill point angle suits general-purpose hole entry in aluminum
• 2-flute regular spiral design promotes chip evacuation in through and blind holes
• DIN 6539 compliant with straight-cylindrical shank for broad chuck and collet compatibility
• Stub length construction minimizes deflection in short-reach drilling applications

Compatibility

Designed as an OEM-style replacement or direct tooling selection for screw machine and CNC drilling operations requiring a stub-length solid carbide drill bit in the 0.15-inch to 0.20-inch diameter range per DIN 6539 specification.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the straight-cylindrical shank fully into the collet or chuck and confirm runout before production use. Do not exceed the maximum drilling depth of 0.635 inches per pass without clearing chips to prevent bit breakage in solid carbide tooling.
