Accupro 71177182 Spiral Router Bit 0.25 in Upcut Solid Carbide

Product Description

The ACCUPRO 71177182 is a solid carbide spiral router bit designed for precise upcut milling in aluminum applications. With a 0.25-inch cutter diameter and a 0.375-inch length of cut, this single-edge bit removes chips efficiently by pulling material upward and away from the workpiece. The 22-degree helix angle is optimized for clean entry and reduced heat buildup in non-ferrous metals. At 2 inches overall length and a 1/4-inch shank, it fits standard router chucks and CNC spindle collets used in production and fabrication environments. The bright, uncoated carbide surface is appropriate for aluminum where coating adhesion or chemical reactivity could be a concern.

This bit is specifically suited for routing aluminum plate, including single-sheet and multi-sheet aluminum stock. Right-hand cutting direction makes it compatible with conventional CNC routing setups. The upcut flute style is particularly effective in through-cuts and slotting operations where chip evacuation from the cut zone is critical to finish quality and tool life. Machinists, CNC operators, and fabricators working with aluminum panel or plate material will find this bit well-matched to high-feed-rate passes in production runs or prototype work.

Key Features

• Solid carbide construction for rigidity and wear resistance in aluminum
• Upcut flute geometry promotes chip evacuation away from the cut surface
• 22-degree helix angle balances cutting efficiency and edge stability
• Single-edge router style reduces cutting forces in non-ferrous material
• Bright uncoated finish suitable for aluminum without risk of coating interaction
• Right-hand cutting direction compatible with standard CNC router configurations

Compatibility

Rated for use in single-sheet aluminum, multi-sheet aluminum, and aluminum plate applications. Fits 1/4-inch collets on CNC routers and handheld router platforms. Not piloted.

Installation Notes

Installation should be performed by a qualified CNC operator or machinist with the spindle fully powered down and locked before bit exchange. Seat the shank fully into the collet and torque the collet nut according to the router or spindle manufacturer specifications. Confirm cutter runout with a dial indicator before production use to protect both the bit and the workpiece. Always follow applicable machine guarding and PPE requirements when operating routing equipment.
