Guhring 9005150095200 Drill Bit 3/8 Inch Powdered Metal

Product Description

The GUHRING 9005150095200 is a stub-length, screw machine drill bit engineered for high-performance drilling in ferrous materials. Built from powdered metal (PMASP60 grade) with a coated finish, this bit delivers durability and heat resistance across demanding production environments. It measures 0.375 inches in diameter with an overall length of 84 millimeters (approximately 3.31 inches) and a flute length of 40 millimeters (approximately 1.57 inches). The 130-degree cone relief point and parabolic flute geometry reduce cutting forces and improve chip evacuation. Manufactured to DIN 1897 standards, this drill bit is suited for use by machinists, tool-and-die professionals, and industrial maintenance technicians.

This drill bit is designed for right-hand cutting in cast iron and steel workpieces. The stub-length (screw machine) format provides added rigidity compared to jobber-length bits, making it well suited for CNC machining centers, drill presses, and manual turret lathes where short overhang and precise hole location are required. The parallel web configuration and web-thinned point reduce thrust load at entry and maintain straightness in production drilling runs. It is appropriate for residential shop, commercial, and industrial applications where repeated hole drilling in steel or cast iron is the primary task.

Key Features

• Powdered metal construction (PMASP60) with coated finish for wear and heat resistance
• 130-degree cone relief drill point for reduced thrust and improved center accuracy
• Parabolic flute design promotes efficient chip evacuation during deep cuts
• Web-thinned, parallel web configuration lowers entry force in hard materials
• Stub-length format (DIN 1897) adds rigidity and reduces deflection
• Maximum drilling depth of 1.131 inches (28.72 millimeters) at 3xD flute-to-diameter ratio

Compatibility

Designed as a DIN 1897-compliant stub-length drill bit suitable for use in standard straight-shank drill chucks across CNC machining centers, drill presses, and turret lathes. Primary workpiece materials are cast iron and steel.

Installation Notes

Installation and operation should be performed by qualified machinists or maintenance technicians familiar with rotary cutting tools. Ensure the drill chuck is fully secured and the workpiece is firmly clamped before initiating a cut. Disconnect or lock out machine power before changing bits or inspecting the cutting edge. Do not exceed the maximum drilling depth of 1.131 inches in a single pass without clearing chips, particularly in blind-hole applications.
