Guhring 9005040047600 Extra Length Drill Bit 3/16 in Hss

Product Description

The GUHRING 9005040047600 is a high-speed steel extra length drill bit engineered for deep hole drilling applications. Manufactured to DIN 1869 standards, this Series 504 bit carries a 3/16 inch (0.1875 inch) diameter with a parabolic flute geometry and a web-thinned, tapered web configuration. The 130-degree chisel point provides aggressive entry and controlled chip evacuation. With a maximum drilling depth of 8.2677 inches and a right-hand cutting direction, this bit delivers consistent performance in production and maintenance environments. It is installed by machinists, toolroom technicians, and metalworking professionals requiring extended reach beyond standard jobber-length tooling.

This drill bit is rated as a high-performance grade tool with primary workpiece material compatibility in aluminum and similar non-ferrous and ferrous materials classified under material codes K, N, and P. The 30xD flute-to-diameter ratio makes it well suited for deep-hole operations in CNC machining centers, drill presses, and manual machines where chip clearance and hole straightness are critical. The straight-cylindrical shank seats directly into standard drill chucks or collet holders without adapters.

Key Features

• Parabolic flute geometry promotes efficient chip evacuation in deep-hole drilling up to 8.2677 inches depth
• 130-degree chisel point with web-thinned, tapered web for reduced thrust and cleaner entry
• High-speed steel (M2 grade) construction, uncoated, suitable for aluminum and similar workpiece materials
• Straight-cylindrical shank at 0.1875 inch diameter fits standard chucks and collet systems without modification
• Manufactured to DIN 1869 standard, Series 504, high-performance drill bit grade
• Right-hand cutting direction with 2-flute design; no coolant-through feature

Compatibility

Designed as an OEM-style deep-hole drill for use in standard drill chucks and collet holders accepting a 3/16 inch straight-cylindrical shank, compatible with CNC machining centers, drill presses, and manual drilling equipment requiring extended-length tooling per DIN 1869 Series 504 specifications.

Installation Notes

This bit is installed by machinists or toolroom technicians; ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the straight-cylindrical shank fully into the chuck or collet and verify runout before beginning a drilling cycle. As this bit carries no coolant-through capability, apply external cutting fluid or mist coolant appropriate for the workpiece material to manage heat at depth. Follow machine manufacturer guidelines for feed rate and spindle speed when drilling to the full 8.2677 inch depth capacity.
