Guhring 9002230049800 Stub Drill Bit Size 9 Hss

Product Description

The GUHRING 9002230049800 is a stub-length (screw machine length) twist drill bit designed for precision drilling in steel and cast iron. Built to DIN 1897 standards from M2 high-speed steel with an oxide finish, it delivers consistent performance in production and maintenance drilling applications. The bit measures 0.1960 inches (2.4409 inches overall length) with a standard 118-degree point angle and a web-thinned tip that reduces entry force and improves centering accuracy. The straight cylindrical shank and regular spiral flute geometry suit it for use in drill presses, CNC machining centers, and hand-held power tools. Licensed machinists, tool-room technicians, and production floor operators are the primary users.

This drill bit fits applications requiring a compact stub-length tool where clearance is limited or rigidity is prioritized over depth of cut. Its primary workpiece materials are steel and cast iron, making it a standard choice for structural fabrication, general metalworking, and light-duty production runs. The 3xD flute-by-diameter ratio and 18.53 mm maximum drilling depth suit shallow-hole operations. The single-piece HSS construction with oxide coating provides moderate lubricity and corrosion resistance without the added cost of coated carbide tooling.

Key Features

• M2 high-speed steel construction with oxide finish for durability in steel and cast iron
• 118-degree standard point angle with web-thinned, tapered web configuration for improved entry
• Stub (screw machine) length at 2.4409 inches overall for enhanced rigidity in tight clearances
• Right-hand cutting direction with regular spiral flutes for efficient chip evacuation
• Straight cylindrical shank at 0.1961 inches diameter for broad chuck compatibility
• Manufactured to DIN 1897 specification with diameter tolerance of +0.000 to -0.018 mm

Compatibility

Designed as an OEM-compatible stub-length drill bit for use in standard drill chucks, collet holders, and keyed or keyless drill press chucks accepting a straight shank in the 0.1960-inch diameter range. Primary workpiece materials per manufacturer specification are steel and cast iron.

Installation Notes

Installation and use should be performed by a qualified machinist or trained technician. Secure the shank fully in a properly sized chuck or collet before operation and confirm the tool is running true before engaging the workpiece. Always power down and de-energize the machine before changing tooling. Observe applicable shop safety practices including eye protection and appropriate cutting fluid selection for the workpiece material.
