Guhring 9024630075400 Carbide Stub Drill Bit 0.2969 in

Product Description

The GUHRING 9024630075400 is a solid carbide stub-length screw machine drill bit designed for high-precision drilling in demanding shop and production environments. Measuring 0.2969 inches (19/64 inches) in diameter with an overall length of 3.110 inches, this bit features a 118-degree faceted point angle and a web-thinned geometry that reduces thrust and improves hole entry. The 2-flute spiral configuration promotes efficient chip evacuation. It carries a coated finish and is built to DIN 6539 standards, making it a reliable choice for machinists, toolroom technicians, and production line operators working with tight tolerances.

This drill bit is suited for general-purpose drilling operations in aluminum and similar non-ferrous workpiece materials. The stub-length body provides added rigidity compared to standard jobber-length bits, which is advantageous when drilling shallow holes with close dimensional control. It is appropriate for use in CNC machining centers, drill presses, and screw machine setups where runout control and repeatable hole quality are priorities. The straight-cylindrical shank seats directly in standard drill chucks and collet holders without modification.

Key Features

• Solid carbide construction to DIN 6539 and material grade K40 for wear resistance in non-ferrous applications
• 118-degree faceted point with web thinning for reduced entry thrust and improved centering
• Stub-length body (3.110 inches overall) provides greater rigidity than jobber-length equivalents
• 2-flute regular spiral design promotes chip clearance during through and blind hole drilling
• Diameter tolerance held to +0.000 to -0.010 mm for consistent fit and finish
• Coated finish extends tool life in repetitive production drilling cycles

Compatibility

Designed as a general-purpose stub-length carbide drill bit for use in aluminum and non-ferrous workpiece materials; compatible with any setup accepting a straight-cylindrical shank in the 7.54 mm shank diameter range.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out state per applicable machine shop safety procedures. Seat the straight-cylindrical shank fully in a properly sized collet or drill chuck and verify runout before production drilling. Avoid using this carbide bit in interrupted cuts or on hardened ferrous materials beyond its rated application, as carbide is brittle and susceptible to edge chipping under shock loads. Reference the machine manufacturer guidelines and applicable shop standards for spindle speed and feed rate selection.
