Guhring 9005020030000 Extra Length Drill Bit 0.1181 in Hss

Product Description

The GUHRING 9005020030000 is a high speed steel (HSS) extra length drill bit designed for deep hole drilling applications. Built to DIN 1869 standards, it measures 0.1181 inches (3.00 mm) in diameter with a 3.937-inch flute length and a 130-degree drill point angle. The parabolic flute geometry promotes efficient chip evacuation at extended depths, reducing the risk of packing and heat buildup. A web-thinned, tapered web configuration lowers entry resistance and improves point stability. This bit is well suited for licensed machinists, tool-and-die technicians, and trade professionals who require consistent performance in demanding deep hole applications.

This drill bit is intended for deep hole drilling in materials including aluminum and other non-ferrous and ferrous workpiece materials covered under the K, N, and P material codes. The Series 502 designation and DIN 1869 specification place it in the high-performance category for production and maintenance environments. The straight-cylindrical shank fits standard drill chucks and collet holders without adapters, making it straightforward to set up on drill presses, milling machines, and CNC machining centers. The 15xD flute-to-diameter ratio supports drilling to a maximum depth of 3.760 inches (95.50 mm).

Key Features

• DIN 1869 extra length specification — 15xD flute-to-diameter ratio for deep hole reach
• Parabolic flute geometry for efficient chip evacuation at depth
• Web-thinned, tapered web reduces thrust and improves point centering
• 130-degree drill point angle suited for aluminum and general-purpose work
• Uncoated HSS construction — compatible with standard regrinding workflows
• Right-hand cutting direction with a straight-cylindrical shank for broad chuck compatibility

Compatibility

Designed as an OEM-style extra length drill bit conforming to DIN 1869 standards, suitable for use in standard drill chucks and collet systems accepting a 0.1181-inch straight-cylindrical shank.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with rotating cutting tools. Secure the shank fully in a properly sized chuck or collet before operation, and verify runout is within acceptable limits. Always power down and de-energize the machine spindle before changing tooling. Do not exceed the maximum drilling depth of 3.760 inches without retracting to clear chips, particularly in blind-hole applications.
