Guhring 9005020053000 Extra Length Drill Bit 0.2087in Hss

Product Description

The GUHRING 9005020053000 is an extra length, high speed steel (HSS) twist drill bit engineered for deep hole drilling applications. With a 0.2087-inch diameter, a parabolic flute design, and a 5.315-inch flute length, this bit removes chips efficiently in long-reach situations where standard-length bits cannot reach. It carries a 130-degree drill point angle with web thinning and a tapered web configuration, reducing entry force and improving centering accuracy. Built to DIN 1869 standards at a 15xD flute-to-diameter ratio, it is suited for high-performance production environments. Installation and use require no special tooling beyond a compatible straight-shank chuck or collet holder.

This drill bit is designed primarily for deep hole drilling in aluminum and similar non-ferrous and ferrous workpiece materials. The parabolic flute geometry promotes fast chip evacuation in deep bores, reducing heat buildup and the need for frequent pecking cycles. With a maximum drilling depth of 5.002 inches and a straight-cylindrical shank, it fits standard drill chucks and CNC tool holders used in machine shops, production facilities, and maintenance environments. Licensed machinists, toolroom technicians, and production operators are the typical end users of this Series 502 bit.

Key Features

• 0.2087-inch diameter with tolerance of +0.000 to -0.018 mm for precise bore sizing
• Parabolic flute geometry promotes efficient chip evacuation in deep holes
• 130-degree split point with web thinning reduces thrust and improves self-centering
• Built to DIN 1869 specification for extra length twist drills
• Uncoated HSS construction suitable for aluminum and a range of workpiece materials
• Right-hand cutting direction with straight-cylindrical shank for broad machine compatibility

Compatibility

Designed as a DIN 1869 Series 502 extra length drill bit with a straight-cylindrical shank; fits standard drill chucks and collet holders accepting a 0.2087-inch shank diameter.

Installation Notes

Install in a compatible straight-shank chuck or collet holder and confirm secure engagement before operation. De-energize and lock out the machine before changing tooling, per standard lockout/tagout procedures. Parabolic flute bits in deep hole applications benefit from appropriate cutting fluid or coolant at the tool entry point to manage heat and chip load. Do not exceed the rated maximum drilling depth of 5.002 inches for this bit geometry.
