Guhring 9055240103200 Cobalt Stub Drill Bit 13/32 in

Product Description

The GUHRING 9055240103200 is a cobalt stub-length (screw machine length) drill bit designed for high-performance drilling in demanding materials including steel, stainless steel, cast iron, and aluminum. Built to DIN 1897 standards, this bit measures 13/32 inches (0.4062 inches) in diameter with an overall length of 3.5039 inches (89.00 mm). The 118-degree, 4-facet point geometry combined with web-thinned construction reduces thrust and improves self-centering. The M35 cobalt steel construction provides elevated heat resistance for cutting hard and abrasive workpiece materials. This bit is sold individually and suited for use in machine shop environments and precision trade applications.

This stub-length drill bit is intended for use in screw machines, CNC drilling operations, and manual drill press applications where a shorter flute length is preferred for rigidity and reduced deflection. Its straight cylindrical shank fits standard drill chucks. The Series 5524 design targets production drilling in steel, stainless steel, cast iron, and aluminum and non-ferrous materials. The right-hand cutting direction and regular spiral flute are standard for general-purpose machine drilling in metalworking trades.

Key Features

• M35 cobalt steel construction for heat resistance when drilling hard metals
• 118-degree, 4-facet point with web thinning for reduced entry thrust and improved centering
• DIN 1897 stub-length geometry provides superior rigidity over jobber-length bits
• Straight cylindrical shank fits standard drill chucks without adapters
• Right-hand cut, regular spiral flute for efficient chip evacuation
• Bright/uncoated finish; no coolant-through required

Compatibility

Designed as an OEM-specification replacement or production-use drill bit compatible with steel, stainless steel, cast iron, and aluminum and non-ferrous workpiece materials per DIN 1897 standards. Fits any drill chuck accepting a 0.4063-inch straight cylindrical shank.

Installation Notes

This bit is installed and operated by machinists and metal trade professionals using drill presses, CNC machining centers, or screw machines. Always secure the shank fully in the chuck and verify chuck key removal before operation. Power down and de-energize all equipment before changing tooling. Do not exceed the recommended maximum drilling depth of 1.083 inches per pass without clearing chips.
