Accupro 71177141 Spiral Upcut Router Bit 3/16 in Solid Carbide

Product Description

The ACCUPRO 71177141 is a solid carbide spiral upcut router bit designed for precision routing in aluminum and non-ferrous materials. With a cutter diameter of 0.1875 inches (3/16 inch), a 0.5-inch length of cut, and a 1/4-inch shank, this single-edge bit delivers clean chip evacuation and efficient material removal. The upcut flute geometry pulls chips up and out of the cut, reducing heat buildup and keeping the workpiece clear. A 22-degree helix angle and bright uncoated finish make it well suited for abrasive-friendly applications where coating adhesion is not required. Machinists, toolmakers, and CNC routing professionals use this bit for tight-tolerance work on aluminum stock and similar soft metals.

This router bit is suited for use in CNC routing machines and handheld router setups with a 1/4-inch collet. Its compact 2-inch overall length and single-edge design make it appropriate for plunge cuts, contour routing, and pocket milling in aluminum and comparable non-ferrous workpiece materials. The right-hand cutting direction is standard for conventional CNC spindle operation. It is not piloted, so precise fixturing and depth control are required during operation.

Key Features

• Solid carbide construction for durability and rigidity in non-ferrous routing applications
• Upcut flute geometry evacuates chips away from the cut zone, reducing heat and recutting
• 22-degree helix angle optimized for aluminum and similar materials
• Single-edge design allows higher feed rates with reduced cutting pressure
• Bright uncoated finish compatible with aluminum without chip welding concerns
• Right-hand cutting direction for standard CNC and handheld router spindles

Compatibility

Designed for use in 1/4-inch collet routers and CNC spindles. Optimized for aluminum as the primary material application per manufacturer specifications.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator following standard tooling procedures. Ensure the router or CNC spindle is fully powered down and locked out before changing bits. Insert the shank fully into the collet and tighten to the router or spindle manufacturer's specified torque using the appropriate collet wrench. Verify workpiece fixturing is secure before initiating any cut, as the upcut geometry generates upward forces on the material.
