Guhring 9002230031500 Stub Drill Bit 0.124in Hss

Product Description

The GUHRING 9002230031500 is a stub-length (screw machine length) twist drill bit designed for precision hole-making in metalworking applications. Built from M2 high speed steel with a coated finish, this bit features a 0.124-inch diameter, a 118-degree split point angle, and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The straight-cylindrical shank seats securely in standard drill chucks, and the two-flute regular spiral geometry provides consistent cutting performance. It is used by machinists, tool and die technicians, and maintenance professionals working on production and repair operations.

This bit is suited for drilling cast iron and steel in applications where a shorter flute length is preferred for rigidity and reduced deflection. The stub-length body, conforming to DIN 1897, makes it well-suited for drill press, milling machine, and CNC work where limited spindle clearance or workpiece thickness does not require a jobber-length bit. The maximum drilling depth is 0.523 inches (13.28 mm), and the flute-to-diameter ratio is 3xD. Package quantity is one bit per unit.

Key Features

• M2 high speed steel construction with coated finish for extended tool life in ferrous materials
• 118-degree standard drill point angle with web-thinned, tapered web for reduced entry thrust
• Stub length per DIN 1897 provides added rigidity over jobber-length alternatives
• Right-hand cut, two-flute regular spiral geometry for efficient chip removal
• Straight-cylindrical shank compatible with standard three-jaw and collet-style chucks
• Diameter tolerance of +0.000 to -0.018 mm for consistent, repeatable hole sizing

Compatibility

Designed for drilling cast iron and steel workpieces. Fits standard drill press, CNC, and manual milling machine setups accepting a 3.15 mm (0.124-inch) straight shank. Conforms to DIN 1897 stub-length specification.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician familiar with proper speeds and feeds for HSS drill bits in ferrous materials. Secure the shank fully in the chuck and verify runout before operation. Always wear appropriate eye protection and secure the workpiece before drilling. Do not use on hardened materials beyond the rated workpiece material grades.
