Guhring 9005020032500 Extra Length Drill Bit Hss

Product Description

The GUHRING 9005020032500 is an extra length, high speed steel drill bit engineered for deep hole drilling in demanding production and job-shop environments. Built to DIN 1869 standards, it features a parabolic flute design that efficiently evacuates chips even at extended depths. The 0.128-inch diameter bit carries a 130-degree point angle with web thinning on a tapered web, reducing entry thrust and improving centering on aluminum and other non-ferrous materials. A straight-cylindrical shank seats cleanly in standard drill chucks or collet holders. This bit is sold individually and is intended for use by machinists, tool-and-die professionals, and skilled trades requiring precise deep-hole work.

The 9005020032500 is rated for a maximum drilling depth of 3.942 inches, representing a 15xD flute-by-diameter ratio that places it firmly in the extra length category. Its uncoated HSS construction makes it well suited to aluminum, plastics, and similar non-ferrous workpiece materials as classified under material codes K, N, and P. Typical applications include through-hole operations in production machining, fixture fabrication, and component manufacturing where standard-length bits cannot reach. Right-hand cutting direction is standard.

Key Features

• Parabolic flute geometry for efficient chip evacuation in deep holes
• 130-degree point angle with web-thinned, tapered web reduces entry thrust
• 15xD flute-by-diameter ratio supports deep hole drilling up to 3.942 inches
• High speed steel construction, uncoated, optimized for aluminum and non-ferrous materials
• Straight-cylindrical shank compatible with standard chucks and collet systems
• Manufactured to DIN 1869 specification for consistent dimensional tolerance

Compatibility

Designed as a DIN 1869 Series 502 extra length drill bit suited for deep hole drilling operations in aluminum and non-ferrous workpiece materials (material codes K, N, and P). Consult tooling charts for spindle speed and feed rate compatibility with specific machine platforms.

Installation Notes

Installation and use should be performed by qualified machinists or tooling professionals. Ensure the machine spindle is fully powered down and locked out before changing tooling. Seat the straight-cylindrical shank fully in the chuck or collet and verify runout before beginning a cut. Because this is an extra length bit, reduce feed rates compared to standard-length equivalents and use appropriate cutting fluid or coolant to manage heat, even though the bit does not support through-coolant delivery.
