Guhring 9055100055600 Screw Machine Drill Bit

Product Description

The GUHRING 9055100055600 is a solid carbide screw machine length drill bit designed for high-performance drilling in cast iron and steel. Built to DIN 6537 K standards, this bit features a 140-degree split point (SU type) with web thinning for reduced thrust and improved centering. The two-flute regular spiral design provides efficient chip evacuation in short-hole applications. With an overall length of 66 millimeters and a 28-millimeter flute length, it fits standard screw machine drilling cycles. Coolant-through capability supports higher cutting speeds and longer tool life in production environments. Installed by machinists and tool-and-die professionals in CNC and manual drill press setups.

This drill bit is suited for screw machine length drilling operations in ferrous materials, specifically cast iron and steel. The straight cylindrical shank with a 6-millimeter diameter fits standard collet and drill chuck holders. Its compact flute-to-diameter ratio of 3xD makes it appropriate for shallow to medium-depth holes up to 25 millimeters. Production shops, job shops, and maintenance machinists working with tight-tolerance bores will find the submicron carbide grade and coated finish well matched to high-cycle drilling demands.

Key Features

• Solid carbide submicron grade construction for wear resistance in ferrous materials
• 140-degree SU point with web thinning reduces entry thrust and improves hole location accuracy
• Coolant-through design supports high-speed production drilling and extended tool life
• Two-flute regular spiral geometry promotes controlled chip evacuation in cast iron and steel
• Right-hand cut with straight cylindrical shank for broad collet and chuck compatibility
• Meets DIN 6537 K specification for dimensional consistency and interchangeability

Compatibility

Designed as an OEM-style screw machine length drill bit for use in CNC machining centers, drill presses, and screw machines equipped with standard straight cylindrical collet or chuck holders accepting a 6-millimeter shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Secure the shank fully within the collet or drill chuck to the recommended engagement depth before running the spindle. Confirm coolant-through supply is active before drilling when using this bit in high-speed applications. Always power down and lock out the machine before changing tooling.
