Guhring 9005020049000 Extra Length Hss Drill Bit

Product Description

The GUHRING 9005020049000 is a Series 502 extra length drill bit designed for deep hole drilling in demanding production environments. Built from high-speed steel with a parabolic flute geometry and web-thinned point, it cuts efficiently through aluminum and similar non-ferrous and ferrous materials. The bit measures 0.1929 inches in diameter with a 5.315-inch flute length and an overall length of approximately 7.677 inches, giving it a 15xD flute-to-diameter ratio suited for deep-reach applications. The 130-degree point angle and standard point type promote accurate entry and chip evacuation without coolant-through capability. Licensed machinists, tool-and-die makers, and CNC operators are the typical end users.

This drill bit is primarily intended for deep hole drilling operations in aluminum (material codes K, N, P) and is built to DIN 1869 specification. The straight-cylindrical shank interfaces with standard collet chucks, drill chucks, and toolholders across most CNC machining centers, drill presses, and manual lathes. Its extra length design makes it appropriate for reaching recessed bores, cross-holes, and deep-cavity features that standard-length bits cannot access. Right-hand cutting direction is standard.

Key Features

• Parabolic flute geometry promotes aggressive chip evacuation in deep holes
• Web-thinned, tapered web configuration reduces thrust and improves centering at entry
• 130-degree point angle optimized for non-ferrous and general-purpose work materials
• DIN 1869 standard construction ensures dimensional consistency and interchangeability
• Straight-cylindrical shank fits standard collet and drill chuck toolholding systems
• Uncoated high-speed steel — resharpenable with standard drill grinding equipment

Compatibility

Designed as an OEM-style replacement or direct-use extra length drill bit conforming to DIN 1869 for 0.1929-inch diameter applications in deep hole drilling setups. Primary workpiece material compatibility is aluminum; material codes K, N, and P are referenced in the manufacturer specification data.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator following shop-standard toolholding procedures. Ensure the shank is fully seated and properly torqued in the toolholder before operation, and verify runout with a dial indicator when precision is required. Power down or e-stop the machine before tool changes. Do not exceed the maximum drilling depth of 5.026 inches, and use appropriate cutting fluid or mist lubrication at the workpiece even though the bit does not support coolant-through delivery.
