Guhring 9055100063000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055100063000 is a solid carbide screw machine length drill bit engineered for high-performance drilling in demanding industrial and trade applications. Built to DIN 6537K standards, this Series 5510 bit features a 140-degree split point (SU point type) with web thinning for reduced thrust and improved chip evacuation. The 0.248-inch (6.30 mm) diameter cutting edge and straight-cylindrical shank measuring 8.00 mm accommodate precision drilling in cast iron and steel. Coolant-through capability makes this bit well suited to CNC machining centers and production drilling operations where heat management is critical.

This drill bit is designed for screw machine length applications in metalworking environments, including job shops, production machining, and maintenance facilities. Its 3xD flute-to-diameter ratio and regular spiral flute geometry make it effective for short-hole drilling in cast iron and steel workpieces. The coated solid carbide construction supports high cutting speeds and extended tool life compared to high-speed steel alternatives. Machinists, toolroom technicians, and CNC operators working with ferrous metals are the primary installers and users of this bit.

Key Features

• Solid carbide construction with submicron carbide grade for wear resistance in cast iron and steel
• 140-degree SU point with web thinning reduces entry thrust and improves hole accuracy
• Coolant-through design supports high-speed production drilling and heat control
• DIN 6537K standard ensures dimensional consistency and interchangeability
• Regular spiral flute with parallel web configuration promotes stable chip flow
• Coated finish extends cutting life in abrasive ferrous materials

Compatibility

Designed as an OEM-style replacement and standard-production drill bit for screw machine length drilling applications in cast iron and steel, conforming to DIN 6537K specifications for straight-cylindrical shank carbide drills.

Installation Notes

This bit is installed and operated by machinists and CNC technicians in drill presses, machining centers, and screw machines. Before changing tooling, ensure the spindle is fully stopped and the machine is powered down or placed in a safe state per facility lockout/tagout procedures. Secure the straight-cylindrical shank firmly in a matching collet or drill chuck rated for the shank diameter to prevent runout. Do not exceed the maximum drilling depth of 30.00 mm (approximately 1.18 inches) per the flute length specification.
