Accupro 71176911 Upcut Spiral Router Bit 4mm Solid Carbide

Product Description

The ACCUPRO 71176911 is a single-edge upcut spiral router bit designed for precision milling and routing operations in aluminum applications. Built from solid carbide, this bit delivers the rigidity and edge retention required when cutting aluminum plate, single-sheet aluminum, and multi-sheet aluminum stock. The upcut flute geometry pulls chips up and away from the cut, helping clear material and reduce heat buildup at the cutting zone. With a 4 mm cutter diameter, a 20 mm length of cut, and a 6 mm shank, it fits standard router collets used in CNC routing and manual routing setups. This bit is installed and operated by machinists, CNC operators, and fabricators working with aluminum in production or job-shop environments.

This router bit is suited for light-duty to medium-duty aluminum routing tasks including profiling, slotting, and through-cutting on aluminum plate and sheet. The 22-degree helix angle and right-hand cutting direction are optimized for clean chip evacuation and smooth surface finish on aluminum workpieces. The bright uncoated finish makes it appropriate for aluminum, where certain coatings can cause material adhesion issues. It is packaged individually and sold as a single unit.

Key Features

• Solid carbide construction for rigidity and extended edge retention in aluminum cutting
• Upcut flute style promotes chip evacuation away from the workpiece
• 22-degree helix angle optimized for aluminum plate and sheet applications
• Right-hand cutting direction compatible with standard CNC and manual routers
• Single-edge router style for clean, controlled material removal
• Bright uncoated finish suited for aluminum to prevent material adhesion

Compatibility

Designed for use in aluminum applications including aluminum plates, single-sheet aluminum, and multi-sheet aluminum. Compatible with router setups accepting a 6 mm shank diameter collet.

Installation Notes

This bit should be installed by a qualified machinist or CNC operator familiar with router tooling. Ensure the router spindle is fully powered down and locked out before changing tooling. Confirm the collet is clean and undamaged before seating the 6 mm shank, and torque the collet nut to the router manufacturer specifications. Do not exceed the router or spindle maximum RPM rating for the cutter diameter in use.
