Guhring 9005150102000 Stub Drill Bit 0.4016 in 130 Deg

Product Description

The GUHRING 9005150102000 is a stub-length (screw machine length) drill bit engineered for productive metal removal in cast iron and steel. Built from powdered metal (PMASP60 grade) with a coated finish, this 0.4016-inch diameter bit features a 130-degree split point and a parabolic flute geometry designed to clear chips efficiently at higher feed rates. The web-thinned, parallel-web construction reduces thrust at entry, and the straight-cylindrical shank seats securely in standard drill chucks or screw machine spindles. Overall length is 3.5039 inches with a flute length of 1.6929 inches. Conforms to DIN 1897.

This bit is suited for production drilling operations in machine shops, manufacturing environments, and maintenance settings where short, rigid tooling is preferred over jobber-length bits. The stub length minimizes deflection and improves hole accuracy in interrupted cuts, thin-wall workpieces, and high-cycle screw machine work. Primary target materials are cast iron and steel. The 3xD flute-to-diameter ratio and a maximum drilling depth of 1.0910 inches make it well-matched to shallow, precise holes in ferrous components.

Key Features

• 0.4016-inch diameter with DIN 1897 tolerance: +0.000 to -0.027 mm
• 130-degree standard point angle with web thinning for reduced entry thrust
• Parabolic 2-flute design promotes fast chip evacuation at high feed rates
• Powdered metal (PMASP60) construction with coated finish for extended tool life in ferrous materials
• Stub (screw machine) length for maximum rigidity and minimal deflection
• Straight-cylindrical shank fits standard drill chucks and screw machine collets
• No coolant-through requirement simplifies setup in standard drilling equipment

Compatibility

Designed as a DIN 1897 stub-length replacement drill bit for production drilling applications in cast iron and steel. Fits any drill press, screw machine, or CNC spindle accepting a straight-cylindrical shank of this diameter.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine fully de-energized and at a complete stop. Secure the straight-cylindrical shank firmly in a properly sized collet or drill chuck before operation. Inspect the cutting edges and coating for wear or chipping before each use; a damaged bit should be replaced rather than reused. Follow applicable shop safety standards and machine manufacturer guidelines for speeds, feeds, and coolant practices when drilling ferrous materials.
