Guhring 9005020094000 Extra Length Hss Drill Bit 0.3701in

Product Description

The GUHRING 9005020094000 is a high speed steel extra length drill bit engineered for deep hole drilling applications. With a 0.3701 inch diameter and a parabolic flute design, it efficiently evacuates chips during extended-reach cuts. The straight-cylindrical shank and web-thinned tip geometry reduce entry thrust and improve centering on the workpiece. Built to DIN 1869 standards, this bit covers a 15xD flute-to-diameter ratio and reaches a maximum drilling depth of 6.335 inches. It is uncoated and ground for right-hand cutting. Licensed machinists, tool-and-die shops, and precision fabricators rely on this geometry for consistent bore quality in deep hole work.

This drill bit is suited for deep hole drilling in aluminum and other non-ferrous and general-purpose materials. The parabolic flute profile promotes fast chip ejection in long-reach cuts where chip packing is a common failure point. With a 6.89 inch flute length and a 250 mm overall length, it fits machining centers, drill presses, and CNC setups where standard-length drills fall short. The Series 502 designation aligns this bit with a coordinated line of GUHRING deep hole tooling. It is appropriate for both production and maintenance environments where precision bore depth is required.

Key Features

• Parabolic flute geometry promotes aggressive chip evacuation in deep hole applications
• Web-thinned tip with tapered web configuration reduces thrust and improves self-centering
• Built to DIN 1869 specification for extra length twist drills
• 15xD flute-to-diameter ratio supports drilling depths up to 6.335 inches without a peck cycle
• Uncoated high speed steel construction suitable for aluminum and compatible workpiece materials
• Straight-cylindrical shank provides positive grip in standard drill chucks and collets

Compatibility

Designed as an OEM-style replacement or direct tooling selection for setups requiring a 0.3701 inch diameter extra length drill conforming to DIN 1869. Primary workpiece material is aluminum; material codes K, N, and P indicate suitability for non-ferrous metals and plastics as classified under standard cutting material designations.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Secure the straight-cylindrical shank fully into a collet or drill chuck rated for the shank diameter before starting the spindle. Confirm machine spindle speed and feed rate are set for high speed steel tooling and the target material before engaging the cut. Do not exceed the maximum drilling depth of 6.335 inches without verifying chip clearance and coolant or lubrication strategy.
