Guhring 9005020038000 Extra Length Hss Drill Bit

Product Description

The GUHRING 9005020038000 is a high speed steel extra length drill bit designed for deep hole drilling applications in metalworking and machining environments. Built to DIN 1869 standards, this Series 502 bit features a parabolic flute geometry with web thinning and a tapered web configuration that promotes efficient chip evacuation at greater depths. It measures 0.1495 inches in diameter with a 4.724-inch flute length and a 6.89-inch overall length, giving it a flute-to-diameter ratio of 15xD. The straight-cylindrical shank diameter is 0.1496 inches. This tool is installed and operated by machinists and tooling technicians working on CNC and manual drilling equipment.

This drill bit is suited for deep hole drilling in aluminum and similar non-ferrous and ferrous workpiece materials. The parabolic flute profile reduces friction and improves chip flow in blind and through-hole applications where standard-length bits cannot reach. The uncoated high speed steel construction is appropriate for use with aluminum and other materials classified under primary workpiece material codes K, N, and P. Right-hand cutting direction is standard for conventional spindle rotation. Wire size designation is number 25, equivalent to 3.80 mm. Maximum drilling depth is rated at 5.000 inches (114.30 mm).

Compatibility

Designed as a DIN 1869 Series 502 extra length drill bit suitable for deep hole drilling in aluminum and similar workpiece materials classified under material codes K, N, and P. Compatible with standard drill chucks and collet systems accepting a 0.1496-inch straight-cylindrical shank.

Installation Notes

Installation and operation of this drill bit should be performed by qualified machinists familiar with drilling speed and feed parameters for the target workpiece material. Ensure the drill chuck or collet is properly tightened and the shank is fully seated before spindle activation. Coolant-through is not supported; apply cutting fluid externally as required by the workpiece material and depth. Do not exceed the maximum drilling depth rating of 5.000 inches for this bit.
