Guhring 9005520013200 Screw Machine Drill Bit Hss

Product Description

The GUHRING 9005520013200 is a screw machine length drill bit designed for fast, accurate drilling in aluminum and other non-ferrous materials. Built from high speed steel (HSS) with a bright, uncoated finish, it features a parabolic flute geometry that promotes efficient chip evacuation and reduces heat buildup during operation. The 130-degree split point enters material quickly and resists walking without a center punch. With a straight-cylindrical shank and a 5/16-inch flute length, this bit fits standard drill chucks and is sized for screw machine (stub) length applications where rigidity and precision matter. It is used by machinists, tool-and-die professionals, and production shop technicians.

This drill bit is engineered for screw machine and CNC drilling operations where shorter flute length provides greater rigidity and improved hole accuracy. The parabolic flute with a 3xD flute-to-diameter ratio is particularly effective in aluminum, where chip packing and built-up edge are common concerns. The web-thinned, parallel web configuration reduces thrust force at the tip, making it well suited to high-cycle production environments and close-tolerance hole work. It conforms to DIN 1897 standards for screw machine length drill bits.

Key Features

• 130-degree drill point angle for fast penetration and reduced walking
• Parabolic flute geometry promotes efficient chip evacuation in aluminum
• Web-thinned parallel web reduces axial thrust force
• Bright/uncoated HSS construction for general-purpose screw machine length drilling
• Straight-cylindrical shank fits standard drill chucks and collets
• Conforms to DIN 1897 screw machine length drill standard

Compatibility

Designed as an OEM-style screw machine length drill bit per DIN 1897, suitable for use in standard drill presses, CNC machining centers, and screw machines accepting a straight-cylindrical shank.

Installation Notes

Installation and use of this drill bit should be performed by a qualified machinist or tooling technician. Secure the shank fully in a properly sized collet or drill chuck before operation, and verify chuck runout is within acceptable tolerance for the application. Always wear appropriate eye protection and secure the workpiece before drilling. Follow shop-specific feeds, speeds, and coolant guidelines for the workpiece material and machine type.
