Guhring 9005520020600 Screw Machine Drill Bit Hss

Product Description

The GUHRING 9005520020600 is a stub-length screw machine drill bit designed for high-throughput drilling in production and machining environments. Built from high-speed steel (HSS) with a bright/uncoated finish, it cuts a 0.081 inch diameter hole with a 130-degree point angle and a parabolic flute geometry. The parabolic flute promotes efficient chip evacuation, reducing heat buildup and cycle time. Overall length is 1.5 inches with a flute length of 15/32 inches, making it well suited for CNC drilling centers, drill presses, and screw machines where a short, rigid setup is required. This bit is right-hand cut and carries a DIN 1897 specification.

This drill bit is primarily rated for aluminum as the target workpiece material, though its HSS construction handles a range of non-ferrous and soft ferrous materials in production drilling applications. The straight cylindrical shank fits standard drill chucks without adapters. A maximum drilling depth of 0.351 inches suits shallow-hole applications common in screw machine work, fixture drilling, and parts manufacturing. The web-thinned, parallel web configuration reduces thrust force at the point, improving entry performance in repetitive-cycle operations.

Key Features

• 0.081 inch diameter with a wire gauge size of No. 46
• 130-degree standard point angle for positive entry and reduced walking
• Parabolic flute geometry for improved chip evacuation in high-cycle drilling
• Web-thinned parallel web reduces thrust force at drill entry
• Bright/uncoated HSS construction rated for aluminum and soft metals
• Conforms to DIN 1897 stub-length specification

Compatibility

Designed as an OEM-style replacement or production-supply drill bit for use in standard drill chucks and collet systems accepting straight cylindrical shanks in CNC machining centers, drill presses, and screw machines.

Installation Notes

Installation and use of this drill bit should be performed by a qualified machinist or tooling technician familiar with CNC or manual drilling equipment. Ensure the spindle is fully stopped and the machine is de-energized or in a safe state before changing tooling. Secure the straight shank firmly in the chuck or collet to the manufacturer-specified runout tolerance before operation. Do not exceed the rated maximum drilling depth of 0.351 inches per cycle without retracting to clear chips.
