Guhring 9024630060400 Carbide Stub Drill Bit 0.238 in

Product Description

The GUHRING 9024630060400 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 and manufactured from K40 carbide grade, this bit delivers consistent hole quality in demanding applications. It features a 118-degree faceted point angle, two spiral flutes with web thinning, and a straight-cylindrical shank. The 0.238-inch (Letter B) diameter and compact stub-length body make it well suited for rigid setups where shorter overhang reduces deflection and improves positional accuracy.

This drill bit is rated for general-purpose use with aluminum as the primary workpiece material, though its solid carbide construction supports use in other non-ferrous and engineered materials where high rigidity is required. The stub-length profile is common in CNC machining centers, screw machines, and drill press applications where tool clearance is limited and hole depth does not exceed maximum drilling depth. It is sold individually with a minimum order quantity of one.

Key Features

• Solid carbide K40 grade construction for rigidity and wear resistance
• 118-degree faceted point angle with web thinning for clean entry and reduced thrust
• Stub-length (3xD flute-to-diameter ratio) for reduced deflection in short-hole applications
• Right-hand spiral flute with coated finish for improved chip evacuation
• DIN 6539 standard compliance for dimensional consistency
• Straight-cylindrical shank compatible with standard collets and chucks

Compatibility

Designed as a DIN 6539-compliant stub-length carbide drill bit with a 6.04 mm straight-cylindrical shank, compatible with standard collet chucks and drill holders accepting that shank diameter.

Installation Notes

Installation and use should be performed by a qualified machinist or CNC operator. Secure the shank fully in a compatible collet or chuck and verify runout before drilling. Ensure spindle speed and feed rate are appropriate for the workpiece material and bit diameter before operation. Do not exceed the maximum drilling depth of 0.864 inches per pass without retracting to clear chips.
