Guhring 9006530030000 Stub Drill Bit 3 Mm Hss 118 Point

Product Description

The GUHRING 9006530030000 is a screw machine length (stub) drill bit designed for fast, accurate hole-making in ferrous materials. Built to DIN 1897 standards from M2 high-speed steel with a coated finish, this bit delivers consistent performance in production and repair environments. The 118-degree cone relief point initiates cleanly without a center punch on most setups. At 3 mm diameter and 46 mm overall length, this stub-length geometry provides rigidity in short-reach applications where standard-length bits would flex or wander. Licensed machinists, tool-and-die technicians, and maintenance tradespeople are the primary users of this type of bit.

This drill bit is suited for drilling into cast iron and steel in screw machine, drill press, and CNC applications where a short, stiff bit is required to hold positional accuracy. The stub length reduces overhang, minimizing deflection during entry. The straight-cylindrical shank accepts standard drill chucks without a collet adapter. Maximum drilling depth is 11.50 mm (0.453 inches), making it appropriate for through-holes and shallow blind holes in production runs or field repair work.

Key Features

• DIN 1897 stub-length geometry for increased rigidity and reduced deflection
• M2 high-speed steel construction rated for cast iron and steel workpieces
• 118-degree cone relief point with web thinning for improved chip evacuation and reduced thrust
• Right-hand cut with regular spiral flutes; 2-flute configuration
• Straight-cylindrical shank (3 mm diameter) fits standard drill chucks directly
• Diameter tolerance h8 for consistent fit in close-tolerance work

Compatibility

Designed as a DIN 1897 stub drill bit for use in screw machine operations, drill presses, and CNC drilling on cast iron and steel workpieces. Part of the GUHRING Series 653 heavy-duty stub drill line.

Installation Notes

Install in a drill chuck or collet rated for the 3 mm shank diameter and ensure the chuck is tightened securely before operation. Power down the machine and lock out energy sources before changing bits. Verify spindle speed is appropriate for the workpiece material and bit diameter per standard machining tables. Do not exceed the 11.50 mm maximum drilling depth in a single pass without pecking to clear chips.
