Guhring 9005020110000 Extra Length Drill Bit 11 Mm Hss

Product Description

The GUHRING 9005020110000 is an extra length high-speed steel drill bit designed for deep hole drilling in production and maintenance environments. Built to DIN 1869 standards, it features a 130-degree point angle with a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The parabolic flute geometry supports consistent chip flow even at extended depths. At 280 mm overall length with a 195 mm flute length, this bit delivers the reach required for through-hole and deep-feature applications that standard-length drills cannot address. It is sized at 11 mm diameter and suited for use by machinists and toolroom technicians.

This drill bit is rated for deep hole drilling up to 178.5 mm, making it well-suited for aluminum and similar non-ferrous workpiece materials, as well as select ferrous applications. The straight-cylindrical shank fits standard drill chucks and collet holders without adapters. The Series 502 designation places it within a line engineered for high-performance material removal at extended reach. It is appropriate for CNC machining centers, drill presses, and manual equipment where repeatable accuracy at depth is required.

Key Features

• DIN 1869 extra length standard for deep hole drilling up to 178.5 mm depth
• 130-degree point angle with web thinning for reduced entry thrust
• Parabolic flute design promotes efficient chip evacuation at extended depths
• High-speed steel construction with nitride coating finish
• Straight-cylindrical shank compatible with standard chucks and collet systems
• Right-hand cutting direction, 2-flute configuration

Compatibility

Designed as a DIN 1869 Series 502 extra length drill bit for deep hole drilling applications, primarily in aluminum and non-ferrous workpiece materials, with a straight-cylindrical shank for use in standard drill chucks and collet holders.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with cutting tool setup. Secure the workpiece and confirm the chuck or collet is properly torqued before operation. At extended lengths, reduce feed rate and spindle speed compared to standard-length tooling to minimize deflection and bit breakage. Inspect the cutting edges and point geometry before each use.
