Guhring 9003050008400 Cobalt Drill Bit 0.0331 in 118 Deg

Product Description

The GUHRING 9003050008400 is a cobalt jobber length drill bit designed for precision drilling in demanding trade and industrial applications. Built to DIN 338 standards, this bit features a 0.0331-inch diameter with a 118-degree cone relief point and a bright uncoated finish. The two-flute spiral design with web thinning promotes clean chip evacuation and reduces the thrust required to start the cut. With an overall length of 30.00 mm and a straight cylindrical shank measuring 0.84 mm in diameter, it fits standard collet and chuck systems. This bit is suited for machinists, fabricators, and maintenance technicians who need reliable performance in small-diameter drilling tasks.

This Series 305 drill bit is rated for general purpose use and is optimized for cutting cast iron and steel. The regular spiral flute geometry and right-hand cut make it appropriate for standard drill press, CNC, or hand-held power tool applications where small, precise holes are required. The h8 diameter tolerance ensures consistent fit and repeatable results across production runs or repair work. Maximum drilling depth is 0.344 inches (8.74 mm), making it well suited for shallow-hole operations in ferrous workpieces typical in HVAC equipment fabrication, pipe work, and panel drilling.

Key Features

• Cobalt construction for improved heat and wear resistance in ferrous materials
• 118-degree cone relief point with web thinning for easier penetration and reduced walking
• Two-flute regular spiral design for efficient chip removal
• Bright uncoated finish suitable for use with cutting fluids
• DIN 338 standard geometry ensures dimensional consistency
• Right-hand cut, straight cylindrical shank compatible with standard drill chucks and collets

Compatibility

Designed as an OEM-style replacement or direct-use jobber length drill bit for general purpose drilling operations in cast iron and steel workpieces, compatible with standard straight-shank drill chucks and collet systems accepting a 0.84 mm shank diameter.

Installation Notes

This bit is installed by machinists or trade technicians using a compatible drill chuck or collet system. Ensure the shank is fully seated and secured before operation. Use appropriate cutting fluid or coolant when drilling steel to extend tool life and maintain dimensional accuracy. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed to prevent workpiece damage or bit breakage.
