Guhring 9005020088000 Extra Length Hss Drill Bit

Product Description

The GUHRING 9005020088000 is a high speed steel extra length drill bit engineered for deep hole drilling applications requiring extended reach and precise bore geometry. Built to DIN 1869 standards, this Series 502 bit features a parabolic flute design that promotes efficient chip evacuation in deep cuts. The 130-degree drill point and web-thinned, tapered web configuration reduce cutting forces and improve centering on entry. At 0.3465 inches in diameter with a flute length of 6.89 inches and an overall length of 250.00 mm, this bit is suited for professionals who need reliable performance beyond standard length tooling.

This drill bit is intended for use in deep hole drilling operations, with a primary workpiece material designation of aluminum and non-ferrous or general steel materials as indicated by the K, N, and P material codes. The parabolic flute geometry accelerates chip removal in blind and through-hole applications, reducing heat buildup and the need for peck cycles. It is installed in machine tool spindles with a straight-cylindrical shank and is appropriate for use in CNC machining centers, drill presses, and manual milling machines running controlled feed rates.

Key Features

• Parabolic flute geometry promotes fast chip evacuation in deep hole drilling
• 130-degree drill point with web thinning for reduced entry force and improved self-centering
• High speed steel construction, uncoated, suited for aluminum and general metal applications
• Flute-to-diameter ratio of 15xD provides extended reach capability
• Straight-cylindrical shank for standard collet and chuck compatibility
• Manufactured to DIN 1869 specification for consistent dimensional accuracy

Compatibility

Designed as a DIN 1869 Series 502 extra length drill bit for deep hole drilling in aluminum and compatible workpiece materials designated under material codes K, N, and P.

Installation Notes

This bit is installed and operated by machinists and tool-and-die professionals in machine tool applications. Before installation, verify the spindle or chuck is fully powered down and secured. Use a collet or chuck sized to accept a 0.3465-inch straight-cylindrical shank. Confirm feed rate and speed settings are appropriate for the workpiece material and bit diameter before initiating a cut to avoid bit deflection or premature wear.
