Guhring 9002230047600 Screw Machine Drill Bit 3/16in

Product Description

The GUHRING 9002230047600 is a screw machine length (stub) drill bit designed for high-speed steel cutting applications in metal fabrication and machining environments. Built to DIN 1897 standards, this 3/16 inch diameter bit features a 118-degree standard point angle and a web-thinned geometry that reduces entry force and improves chip evacuation. The straight-cylindrical shank measures 0.1875 inches in diameter and is compatible with standard drill chucks. With an overall length of 2.44 inches and a flute length of approximately 1.02 inches, this short-length design provides rigidity and minimizes deflection in shallow-hole applications. It is intended for use by machinists, maintenance technicians, and fabricators working with cast iron and steel workpieces.

This stub-length drill bit is suited for production drilling, screw machine operations, and CNC or manual drill press work where a shorter, stiffer tool is preferred over jobber-length alternatives. The 3xD flute-to-diameter ratio and parallel web configuration make it well-matched for repetitive hole operations in ferrous materials, particularly cast iron and steel. The right-hand spiral flutes and 118-degree point geometry are standard for general-purpose drilling in these materials. Maximum drilling depth is 0.743 inches, making this bit appropriate for shallow through-hole and blind-hole applications in production or maintenance settings.

Key Features

• DIN 1897 stub-length design provides increased rigidity and reduced deflection compared to jobber-length bits
• 118-degree standard point angle with web-thinned tip reduces thrust force on entry
• High-speed steel (HSS) construction with coated finish for extended tool life in ferrous materials
• Straight-cylindrical shank (0.1875 inches diameter) fits standard drill chucks without adapters
• Right-hand cut with regular spiral flutes for efficient chip clearing in cast iron and steel
• Maximum drilling depth of 0.743 inches suits shallow through-hole and blind-hole operations

Compatibility

Designed as a DIN 1897-compliant stub-length drill bit for use in standard drill chucks, CNC machining centers, and screw machines accepting a 0.1875 inch straight-cylindrical shank. Primary workpiece materials are cast iron and steel.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools. Ensure the drill chuck is fully tightened and the workpiece is securely fixtured before operation. Always power down the machine and bring the spindle to a complete stop before changing bits or clearing chips. Follow applicable shop safety standards and the machine manufacturer's operating guidelines for speed and feed selection.
