Guhring 9005520045700 Screw Machine Drill Bit 0.18 in

Product Description

The GUHRING 9005520045700 is a stub-length, screw machine drill bit designed for high-throughput drilling in production and machining environments. Built from high-speed steel with a bright, uncoated finish, it measures 0.1800 inches in diameter and features a 130-degree point angle with a parabolic flute geometry. The parabolic flute design promotes rapid chip evacuation and reduces heat buildup during extended drilling cycles. At 2-9/32 inches overall length with a 15/16-inch flute length, this bit fits standard straight-cylindrical shank chucks. It carries a DIN 1897 specification and is web-thinned for reduced thrust force at entry. Licensed machinists, tool-and-die technicians, and CNC operators are the primary installers.

This drill bit is optimized for aluminum as its primary workpiece material, making it well-suited for automotive, aerospace, and general metalworking applications where clean, fast hole entry in non-ferrous stock is required. The stub-length body minimizes deflection in short-depth drilling operations. With a maximum drilling depth of 0.6750 inches and a flute-to-diameter ratio of 3xD, it handles common production hole depths without regrinding. It ships in single-piece quantity and is suited for bench drill presses, CNC machining centers, and hand-held power tools with compatible chucks.

Key Features

• Parabolic flute geometry accelerates chip evacuation and reduces heat in continuous-cycle operations
• 130-degree point angle with web-thinned tip lowers entry thrust and improves centering on aluminum
• High-speed steel construction with bright uncoated finish for standard lubrication environments
• Stub-length body (DIN 1897) minimizes deflection and increases rigidity in short-depth holes
• Right-hand cutting direction with straight-cylindrical shank for broad chuck compatibility
• Diameter tolerance of +0.000 to -0.018 mm for consistent fit in tolerance-critical applications

Compatibility

Designed as an OEM-style replacement or direct-use drill bit conforming to DIN 1897 stub-length standards, compatible with straight-cylindrical shank drill chucks across bench, CNC, and portable drilling platforms.

Installation Notes

Installation and use should be performed by qualified machinists or tool-and-die technicians. Ensure the drill chuck is fully tightened and the workpiece is securely clamped or fixtured before initiating a cut. Disengage all power to the spindle before inserting or removing the bit. Apply appropriate cutting fluid or lubricant for aluminum stock to extend tool life and maintain surface finish quality.
