Accupro 71177109 Spiral Router Bit 0.125 in Upcut Solid Carbide

Product Description

The ACCUPRO 71177109 is a solid carbide upcut spiral router bit designed for precision cutting in aluminum applications. With a 0.125 inch cutter diameter and a 0.5 inch length of cut, this bit removes chips aggressively by pulling material upward and away from the workpiece, reducing heat buildup and extending tool life in nonferrous metals. The single-edge, right-hand cutting geometry paired with a 22-degree helix angle keeps chip evacuation efficient and cutting forces manageable. At 2 inches overall length and a 1/4 inch shank diameter, it mounts directly in standard router chucks and CNC spindle toolholders. Machinists, CNC operators, and fabricators working with aluminum sheet and plate stock will find this bit sized for slot routing, profiling, and through-cutting operations.

This bit is engineered specifically for aluminum, including single-sheet aluminum, multi-sheet aluminum stacks, and aluminum plate. Its upcut flute geometry is well suited to CNC router tables and handheld router setups where chip clearance from the top surface is a priority. The bright uncoated carbide finish is appropriate for aluminum, where certain coatings can cause material adhesion. This is a practical choice for shops doing panel work, sign fabrication, enclosure routing, or any light-to-medium aluminum profiling task where a small-diameter tool is required.

Key Features

• Solid carbide construction for rigidity and wear resistance in nonferrous metal cutting
• Upcut single-edge flute pulls chips up and away from the cut, reducing recutting and heat
• 22-degree helix angle optimized for aluminum chip evacuation
• Right-hand cutting direction compatible with standard CNC and handheld router rotation
• Bright uncoated finish appropriate for aluminum to prevent material buildup on cutting edges
• 1/4 inch shank fits widely available router collets and CNC toolholders without adapters

Compatibility

Designed for use in aluminum plates, single-sheet aluminum, and multi-sheet aluminum applications. Fits any router or CNC spindle accepting a 1/4 inch shank collet.

Installation Notes

This bit should be installed by a machinist or CNC operator familiar with router tooling and nonferrous cutting parameters. Ensure the router or CNC spindle is fully powered down and locked out before changing tooling. Seat the shank fully into the collet and tighten to the tool manufacturer's specified torque range for 1/4 inch tooling. Verify workpiece clamping is secure before beginning any cut, as small-diameter carbide bits are sensitive to lateral deflection and can fracture if feed rates are not appropriate for the material thickness.
