Guhring 9005020051600 Extra Length Hss Drill Bit 0.2031in

Product Description

The GUHRING 9005020051600 is a high-speed steel extra length drill bit engineered for deep hole drilling applications in metalworking and machining operations. Measuring 0.2031 inches in diameter with a 7.677-inch overall length and a 5.315-inch parabolic flute, this bit delivers efficient chip evacuation at depth. The 130-degree drill point angle and web-thinned, tapered web configuration reduce entry force and improve centering accuracy. Conforming to DIN 1869 standards, it is rated as a high-performance drill bit suitable for demanding production and maintenance environments. Machinists and toolroom technicians are the primary installers and users.

This bit is designed primarily for deep hole drilling in aluminum and similar non-ferrous and ferrous workpiece materials, as indicated by material codes K, N, and P. The 15xD flute-to-diameter ratio and 5.010-inch maximum drilling depth make it well suited for through-hole and blind-hole work where standard-length drills cannot reach. The straight-cylindrical shank fits standard drill chucks and collet holders commonly found on drill presses, CNC machining centers, and manual mills. It ships in single-unit packaging and carries a minimum order quantity of one.

Key Features

• Parabolic flute geometry promotes rapid chip evacuation during deep hole drilling
• 130-degree drill point angle with web thinning reduces thrust force and improves self-centering
• 15xD flute-to-diameter ratio supports drilling depths up to 5.010 inches (127.26 mm)
• Uncoated high-speed steel construction; compatible with standard cutting fluids and coolants
• Straight-cylindrical shank fits conventional drill chucks and ER collet systems
• Manufactured to DIN 1869 specification for consistent dimensional tolerances

Compatibility

Designed for use in standard drill chucks and collet holders accepting a 13/64-inch straight-cylindrical shank; suitable for deep hole drilling in aluminum and other K, N, and P material group workpieces per DIN material classification.

Installation Notes

This drill bit is installed and operated by machinists, toolroom technicians, and CNC operators. Ensure the spindle and machine are fully stopped and locked out before changing tooling. Secure the shank fully in the chuck or collet to the recommended engagement depth before operation. Use appropriate cutting fluid or coolant for the workpiece material to maintain tool life and surface finish quality.
