Accupro 71177083 Spiral Upcut Router Bit 1/8 Inch Solid Carbide

Product Description

The ACCUPRO 71177083 is a single-edge spiral upcut router bit machined from solid carbide. It carries a 0.125-inch cutter diameter, a 0.5-inch length of cut, and a 1/8-inch shank diameter, with an overall length of 1.5 inches. The upcut geometry pulls chips upward and out of the cut, reducing heat buildup and keeping the flute clear during operation. The bright uncoated finish maintains a sharp edge on non-ferrous materials. This bit is designed for CNC routing and handheld router applications where a small-diameter, high-precision cut is required. Machinists, woodworkers, and fabricators working with aluminum and similar materials are the primary users.

This bit is optimized for aluminum and comparable non-ferrous materials. Its small 0.125-inch diameter makes it well suited for slotting, profiling, and detail routing where tight tolerances are needed. The right-hand cutting direction is compatible with standard router spindle rotation. The 22-degree helix angle balances chip evacuation with cutting stability at typical CNC feed rates. It is appropriate for both production shop and job-site use wherever a 1/8-inch shank collet is available.

Key Features

• Solid carbide construction for rigidity and edge retention in non-ferrous materials
• Upcut flute geometry evacuates chips away from the workpiece surface
• 22-degree helix angle balances cutting stability with efficient chip clearance
• Single-edge design reduces cutting forces on small-diameter passes
• Bright uncoated finish — no coating buildup to affect dimensional accuracy
• Right-hand cutting direction for use with standard router and CNC spindles

Compatibility

Designed for use in routers and CNC machines fitted with a 1/8-inch collet. Optimized for aluminum per manufacturer material application data.

Installation Notes

This bit is installed and serviced by machinists, CNC operators, or skilled fabricators. Power down and lock out the router or spindle before changing bits. Insert the shank fully into the collet and tighten to the tool manufacturer's specified torque range — do not over-tighten a solid carbide shank, as it is brittle under lateral shock. Inspect the cutting edge before each use; carbide chips rather than dulls gradually, and a chipped edge will produce poor surface finish on aluminum.
