Guhring 9005150085000 Stub Drill Bit 0.3346 in Powdered Metal

Product Description

The GUHRING 9005150085000 is a stub-length (screw machine length) twist drill bit designed for high-productivity drilling in ferrous materials. Built from powdered metal (PM) with a coated finish, the bit features a parabolic flute geometry and a web-thinned, parallel-web construction that reduces thrust force at entry and improves chip evacuation. The 130-degree split point starts on contact without a center punch, keeping the hole location accurate. With an overall length of 3.1102 inches and a 0.3346-inch diameter, it fits standard drill chucks and CNC toolholders in machine-shop and production environments. Licensed HVAC, mechanical, and millwright tradespeople encounter this bit in equipment fabrication and service applications.

This bit is suited for drilling cast iron and steel in production and maintenance settings. Its stub-length body provides rigidity in screw machine, turret lathe, and CNC drilling operations where a shorter overhang reduces deflection. The parabolic flute and 3xD flute-to-diameter ratio support efficient chip clearing at moderate to aggressive feed rates. Conforming to DIN 1897, it meets internationally recognized dimensional standards for stub drills, making it a direct fit for applications specifying that specification.

Key Features

• Powdered metal construction with coated finish for extended tool life in ferrous materials
• 130-degree drill point angle with web thinning for reduced thrust and self-starting entry
• Parabolic flute profile promotes fast, clean chip evacuation
• Straight-cylindrical shank at 0.3346 inches fits standard drill chucks and collets
• Stub (screw machine) length body delivers added rigidity over jobber-length bits
• Conforms to DIN 1897 dimensional standard

Compatibility

Designed as a DIN 1897 stub-length drill bit for use in cast iron and steel workpieces; compatible with any drill chuck or collet accepting a 0.3346-inch straight-cylindrical shank.

Installation Notes

Install and remove drill bits only after the spindle has come to a complete stop and the machine is de-energized or locked out per applicable LOTO procedures. Secure the shank fully within the chuck or collet to the recommended grip depth before applying torque. Inspect the cutting edges and coating for wear or chipping before each use; a damaged bit should be replaced, not reconditioned without proper grinding equipment. Follow the machine manufacturer and tooling guidelines for appropriate feed rate and spindle speed for the workpiece material.
