Accupro 71176929 Upcut Spiral Router Bit 5mm Carbide

Product Description

The ACCUPRO 71176929 is a single-edge upcut spiral router bit designed for precise material removal in aluminum applications. Machined from solid carbide, it delivers the rigidity and edge retention required when cutting aluminum plate and sheet stock. The upcut flute geometry pulls chips up and out of the cut, reducing heat buildup and keeping the workpath clear. The 22-degree helix angle balances chip evacuation with edge stability. This bit runs on a 6 mm shank and is sized for light, accurate passes in CNC routing and handheld router setups used by machinists and fabricators.

This router bit is suited for cutting single-sheet aluminum, multi-sheet aluminum stacks, and aluminum plate. The 5 mm cutting diameter and 16 mm length of cut make it well matched to slotting, profiling, and detail work where a small-diameter tool path is required. The bright uncoated finish is appropriate for aluminum, where certain coatings can cause material adhesion. Right-hand cutting direction is standard for conventional CNC router spindle rotation.

Key Features

• Solid carbide construction for rigidity and long edge life in non-ferrous metals
• Upcut flute design evacuates chips away from the workpiece surface
• 22-degree helix angle balances cutting efficiency with tool stability
• Single-edge geometry suited for aluminum plate and sheet applications
• Bright uncoated finish compatible with aluminum to prevent material buildup
• Right-hand cutting direction for standard CNC and handheld router spindles

Compatibility

Designed for use in aluminum plate, single-sheet aluminum, and multi-sheet aluminum applications. Fits any router collet or chuck accepting a 6 mm shank diameter.

Installation Notes

Installation and tool changes should be performed with the router or CNC spindle fully powered down and locked out per standard lockout/tagout procedures. Ensure the collet is clean and undamaged before seating the shank to the recommended insertion depth. Inspect the cutting edge for chips or wear before each use, as carbide tools can fail without visible warning if run after edge damage. Speeds and feeds should be set per the material and machine specifications for small-diameter carbide bits in aluminum.
