Guhring 9024630097000 Carbide Stub Drill Bit 0.3819 in

Product Description

The GUHRING 9024630097000 is a solid carbide, screw machine length (stub) drill bit designed for precision hole-making in production and machining environments. At 9.70 mm (0.3819 inches) in diameter, it runs a 118-degree faceted point angle with a web-thinned tip to reduce entry thrust. The two-flute, right-hand spiral geometry maintains chip flow and dimensional accuracy through the full 1.693-inch flute length. Built to DIN 6539 standards from K40-grade carbide, this bit delivers consistent performance in automated and manual drilling setups where rigidity and repeatability are required.

This stub-length drill bit is engineered for general-purpose drilling with a primary focus on aluminum workpieces, though its K40 solid carbide construction handles a range of non-ferrous and light ferrous materials. The shorter overall length of 3.504 inches provides enhanced rigidity compared to jobber-length bits, making it well-suited for CNC machining centers, drill presses, and screw machine operations where deflection must be minimized. The straight-cylindrical shank seats directly in standard drill chucks and collets without additional adapters.

Key Features

• Solid carbide K40-grade construction for rigidity and wear resistance
• 118-degree faceted point with web thinning reduces entry thrust and improves centering
• Stub length overall (3.504 inches) minimizes deflection in tight setups
• Two-flute regular spiral geometry promotes efficient chip evacuation
• Straight-cylindrical shank compatible with standard chucks and collets
• Meets DIN 6539 specification for consistent dimensional tolerances

Compatibility

Designed as a general-purpose stub-length drill bit conforming to DIN 6539 standards, suitable for use in CNC machining centers, drill presses, and screw machines accepting a 9.70 mm straight-cylindrical shank. Applicable to drilling aluminum and similar workpiece materials within the 9.50 mm to 11.00 mm drill size range category.

Installation Notes

Installation is performed by machinists or toolroom technicians in accordance with machine tool operating procedures. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the straight-cylindrical shank fully into the chuck or collet and verify runout before beginning a drilling cycle. Do not use coolant-through setups with this bit, as it is not designed for internal coolant delivery.
