Guhring 9055100105000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055100105000 is a solid carbide screw machine length drill bit designed for high-performance drilling in ferrous materials. Built to DIN 6537 K standards, it features a 10.50 mm (0.4134 inch) diameter, a 140-degree split point (SU type), and through-coolant capability. The right-hand spiral flute geometry with web thinning reduces thrust and improves chip evacuation. At 102.00 mm overall length with a 55.00 mm flute length, this stub-length drill offers the rigidity needed for precision hole-making on machining centers and drill presses. It is intended for use by machinists and tool-and-die professionals working in production environments.

This drill bit is engineered for cutting cast iron and steel, including applications where coolant-through tooling is required to manage heat in deep or interrupted cuts. The 3xD flute-to-diameter ratio and parallel web configuration suit it to high-cycle production drilling. The 12.00 mm straight-cylindrical shank fits standard ER collet chucks and hydraulic toolholders common in CNC machining centers. It is well suited to job shops, production lines, and maintenance departments where consistent hole tolerance and tool life in steel are priorities.

Key Features

• Solid carbide submicron grade construction for rigidity and wear resistance in ferrous materials
• Through-coolant design delivers cutting fluid directly to the tip, extending tool life in steel and cast iron
• 140-degree SU split point reduces drill walk and lowers entry thrust
• Web-thinned parallel web improves chip flow and reduces cutting force
• Coated finish provides additional surface hardness and lubricity
• DIN 6537 K standard geometry ensures dimensional consistency and interchangeability

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide stub drill for CNC machining centers and manual drill presses accepting a 12.00 mm straight-cylindrical shank. Primary workpiece materials per manufacturer specification are cast iron and steel.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the spindle fully stopped and machine power locked out per shop safety procedures. Seat the straight shank securely in a compatible collet or chuck to the full recommended grip depth before operation. Verify coolant-through passages are clear and coolant pressure is set per machine specifications before engaging the cut. Inspect the cutting edge for chipping or wear before each use, as carbide tooling is brittle and susceptible to damage from improper handling.
