Guhring 9024630048000 Stub Drill Bit 0.189 in Solid Carbide

Product Description

The GUHRING 9024630048000 is a stub-length (screw machine length) solid carbide drill bit designed for precision hole-making in metalworking and machining applications. It carries a 0.189 inch (wire gauge #12) cutting diameter with a 118-degree faceted point angle and a web-thinned tip geometry that reduces entry force and walking. Two spiral flutes in a regular helix evacuate chips efficiently along the 1.024 inch flute length. The straight-cylindrical shank measures 4.80 mm in diameter for direct chuck mounting. At 2.441 inches overall length and 0.05 pounds, this bit is suited for CNC drilling centers, drill presses, and hand-held power tools where a compact stub-length profile is required.

This drill bit is rated for general-purpose use with a primary workpiece material designation of aluminum, though the solid carbide K40 grade substrate handles a range of non-ferrous and ferrous materials at appropriate feed and speed parameters. The stub-length body limits deflection in short-reach operations and makes it well-suited for production environments where hole-to-hole consistency is critical. Maximum drilling depth is 0.74 inches per the Series 2463 design envelope. The coated finish extends tool life under repeated cycling. Installation is performed by licensed machinists or tooling technicians in shop environments.

Key Features

• Solid carbide K40 grade construction for rigidity and wear resistance
• Web-thinned 118-degree faceted point reduces thrust force and improves self-centering
• Stub-length profile minimizes deflection in short-reach and high-cycle drilling
• Two spiral flutes with regular helix for reliable chip evacuation
• Straight-cylindrical shank fits standard drill chucks without adapters
• Conforms to DIN 6539 specification for dimensional consistency

Compatibility

Designed as an OEM-style general-purpose stub-length carbide drill bit conforming to DIN 6539; fits any standard drill chuck or collet accepting a 4.80 mm straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or tooling personnel familiar with cutting tool safety procedures. Always power down and lock out the machine spindle before inserting or removing the bit from the chuck or collet. Ensure the shank is fully seated and the chuck is tightened to the machine specification before beginning a drilling cycle. Do not exceed the maximum drilling depth of 0.74 inches per pass without retracting to clear chips.
