Guhring 9005150022000 Screw Machine Drill Bit 0.0866 in

Product Description

The GUHRING 9005150022000 is a stub-length (screw machine length) twist drill bit built to DIN 1897 standards. Manufactured from powdered metal (PMASP60 grade) with a coated finish, this bit measures 0.0866 inches in diameter with an overall length of 1.5748 inches and a flute length of 0.5118 inches. The 130-degree split point and web-thinned, parallel-web construction reduce entry force and improve chip evacuation. Designed for production and maintenance use, this drill is a practical choice for HVAC fabricators, pipefitters, electricians, and machinists working with ferrous materials in tight-clearance applications where a standard jobber-length drill is too long.

The 9005150022000 is suited for drilling into cast iron and steel in applications where stub-length rigidity matters. The parabolic flute geometry improves chip flow in deeper holes relative to the 0.3820-inch maximum drilling depth. The straight-cylindrical shank fits standard drill chucks without adapters. This bit is sold individually and is appropriate for benchtop drill presses, hand drills, and CNC drilling operations requiring a compact, stiff drill profile.

Key Features

• Stub length per DIN 1897 for maximum rigidity in short-reach drilling
• 130-degree drill point angle reduces thrust and improves hole entry on hard materials
• Parabolic flute with 3xD flute-to-diameter ratio promotes efficient chip removal
• Web-thinned, parallel-web design lowers cutting resistance at the tip
• Powdered metal construction (PMASP60) delivers hardness and wear resistance on cast iron and steel
• Coated finish for extended tool life in ferrous material applications

Compatibility

Designed as a DIN 1897 stub-length drill bit for use in drilling cast iron and steel. Compatible with any drill chuck or collet accepting a straight-cylindrical shank of 0.0866 inches nominal diameter.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists, trade professionals, or trained maintenance personnel. Secure the straight-cylindrical shank firmly in the chuck and verify runout before drilling. Always wear appropriate eye protection and ensure the workpiece is clamped securely before starting the spindle. Do not exceed the rated maximum drilling depth of 0.3820 inches per pass without retracting to clear chips.
