Guhring 9002230019900 Screw Machine Drill Bit Size 47

Product Description

The GUHRING 9002230019900 is a stub-length screw machine drill bit designed for high-speed drilling in metal fabrication, machining, and general mechanical work. Built from M2 high-speed steel with a bright uncoated finish, it carries a wire gauge size of 47, which equals 0.0785 inches in decimal. The 118-degree standard point angle suits most common drilling applications in ferrous and non-ferrous materials. With an overall length of 1.4961 inches and a regular spiral flute, this bit fits standard drill chucks and is sized for screw machine and short-run production use. Installation and use require no special tooling beyond a compatible chuck or collet system.

This drill bit is suited for use in screw machines, drill presses, CNC machining centers, and hand-held power drills where a stub-length tool is preferred for rigidity and reduced deflection. Its straight cylindrical shank and 0.0783-inch shank diameter fit standard chucks. The short overall length of 1.4961 inches makes it appropriate for close-quarter drilling and applications where workpiece clearance is limited. Machinists, tool and die technicians, and production floor operators are the typical end users for this style of bit.

Key Features

• Wire gauge size 47 with 0.0785-inch decimal diameter for precise hole sizing
• M2 high-speed steel construction provides heat resistance during high-speed cutting
• 118-degree standard point angle for general-purpose drilling in a wide range of materials
• Stub length design increases rigidity and reduces lateral deflection
• Bright uncoated finish — no coating to spall or delaminate under heavy use
• Conforms to DIN 1897 specification for consistent dimensional accuracy

Compatibility

Designed as an OEM-style replacement or direct-use stub drill bit compatible with standard straight-shank drill chucks and collets accepting a 0.0783-inch shank diameter.

Installation Notes

This drill bit is installed by machinists and production floor technicians in drill chucks or collet systems. Ensure the shank is fully seated and the chuck is tightened to the manufacturer specification before operation. Disconnect power or engage the e-stop on any machine before changing tooling. Do not exceed the recommended RPM range for the material being drilled, and use appropriate cutting fluid for ferrous materials to extend tool life.
