Guhring 9055100086000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055100086000 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding industrial and machining applications. Built to DIN 6537 K standards, this bit features a 140-degree split point with SU point geometry and web thinning for reduced thrust and cleaner entry. The coated submicron carbide construction delivers extended tool life and edge retention when working in cast iron and steel. With a straight-cylindrical shank and coolant-through capability, it is suited for CNC machining centers and production drilling environments where precision and throughput are critical. Licensed machinists and tool-and-die professionals are the primary installers.

This drill bit is built for production environments where consistent hole quality and tight tolerances are required. The Series 5510 design with a 3xD flute-to-diameter ratio makes it a practical choice for screw machine work, short-hole drilling, and repetitive CNC operations in ferrous materials including cast iron and steel. The parallel web configuration and regular spiral flute promote chip evacuation and reduce heat buildup during high-cycle runs.

Key Features

• Solid submicron carbide construction for extended tool life in ferrous materials
• 140-degree SU split point with web thinning reduces entry thrust and walking
• Coolant-through design supports internal coolant delivery for heat management
• Coated finish improves wear resistance and surface hardness
• DIN 6537 K standard geometry ensures dimensional consistency
• Right-hand cut, 2-flute spiral configuration promotes efficient chip removal

Compatibility

Designed for drilling cast iron and steel workpieces. Compatible with CNC machining centers and screw machines that accept a 10 mm straight-cylindrical shank and support coolant-through tooling.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the spindle fully stopped and machine power isolated. Verify chuck or collet compatibility with the 10 mm straight-cylindrical shank before mounting. Confirm that the machine coolant system pressure is appropriate for coolant-through tooling before initiating a cut. Do not exceed the recommended drilling depth for the flute length to avoid chip packing and tool breakage.
