Guhring 9005520027100 Screw Machine Drill Bit Hss

Product Description

The GUHRING 9005520027100 is a screw machine length (stub) drill bit designed for high-speed steel cutting applications in metal fabrication, machining, and production drilling environments. It carries a 0.1065-inch diameter corresponding to wire size 36 and features a 130-degree split point angle with a parabolic flute geometry. The bright, uncoated finish is suited for general-purpose use, and the web-thinned design reduces thrust force during entry. Right-hand cut direction and a straight-cylindrical shank make this bit compatible with standard drill chucks and CNC tool holders. This bit is manufactured to DIN 1897 standards, reflecting tight dimensional tolerances for precision drilling operations.

This drill bit is intended for stub-length drilling in light-to-medium production environments. The parabolic flute profile promotes efficient chip evacuation, making it particularly effective when drilling aluminum and similar non-ferrous materials. The compact stub length adds rigidity, which reduces deflection in short-hole applications. It is commonly used by machinists, toolroom technicians, and production drillers working on precision components where hole location accuracy is critical. The 3xD flute-to-diameter ratio supports drilling depths up to 0.47 inches without requiring peck cycles in most setups.

Key Features

• Wire size 36 diameter (0.1065 inches) with a tolerance of +0.000 to -0.014 mm for consistent hole sizing
• 130-degree drill point angle with standard point type for positive engagement on entry
• Parabolic flute geometry promotes chip flow and reduces clogging in aluminum and soft metals
• Web-thinned, parallel web configuration lowers axial cutting force
• Stub length adds stiffness and reduces deflection in short-depth drilling applications
• Manufactured to DIN 1897 specification for dimensional and performance consistency

Compatibility

Designed as a DIN 1897 stub-length drill bit with a straight-cylindrical shank, this bit fits standard drill chucks and collet holders sized for 0.1065-inch shank diameters. Primary workpiece material compatibility per manufacturer specification is aluminum; general suitability for other non-ferrous and soft ferrous materials should be verified against application requirements.

Installation Notes

This bit is installed and serviced by machinists and toolroom professionals using standard drill press, mill, or CNC equipment. Before installing or changing bits, de-energize and lock out the machine per applicable safety procedures. Ensure the shank is fully seated and the chuck or collet is properly tightened before initiating a cut. Coolant-through is not supported on this bit; verify that flood or mist coolant delivery is configured externally if required for the application.
