Accupro 71177216 Spiral Router Bit Upcut Solid Carbide

Product Description

The ACCUPRO 71177216 is a solid carbide upcut spiral router bit designed for precision cutting in aluminum applications. With a 0.5-inch cutter diameter and a 1.375-inch length of cut, it handles single-sheet aluminum, multi-sheet aluminum stacks, and aluminum plate stock. The 0.5-inch shank provides a secure fit in standard router chucks and collets. A 22-degree helix angle promotes efficient chip evacuation in the upcut direction, reducing heat buildup and keeping the cut path clear. Right-hand cutting geometry and a bright uncoated finish make this bit well-suited for shops and field setups running aluminum fabrication work.

This bit is used in CNC routing and handheld router applications where clean, burr-minimized cuts in aluminum are required. The upcut flute design pulls chips up and out of the cut, which is especially useful in deep passes through aluminum plate. Metalworking shops, sign fabricators, and industrial maintenance crews working with aluminum sheet goods will find this bit appropriate for both production and repair contexts. The single-edge router style allows aggressive material removal while maintaining dimensional accuracy.

Key Features

• Solid carbide construction for hardness and wear resistance in aluminum cutting
• Upcut flute geometry evacuates chips upward for cleaner cuts and reduced heat
• 22-degree helix angle balances cutting efficiency and edge stability
• Right-hand cutting direction for use with standard router spindle rotation
• Bright uncoated finish suitable for aluminum without coating-adhesion concerns
• 0.5-inch shank diameter fits standard half-inch router collets

Compatibility

Designed for use in aluminum applications including single-sheet aluminum, multi-sheet aluminum, and aluminum plates. Fits routers with a 0.5-inch collet. Not piloted.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down and de-energize the router spindle completely before inserting or removing the bit. Seat the shank fully into the collet and tighten to the router manufacturer's specified torque range. Verify workpiece is securely clamped before initiating a cut.
