Accupro 71176648 Diamond Pattern Router Bit 0.25 in Carbide

Product Description

The ACCUPRO 71176648 is a diamond pattern router bit designed for precision routing in fiberglass and phenolic materials. Built from solid carbide with a bright, uncoated finish, it delivers the hardness and wear resistance needed when cutting abrasive composite materials. The cutter measures 0.25 inches in diameter with a 0.75 inch length of cut and a 2.5 inch overall length. The 0.25 inch shank seats securely in standard router chucks and collets. The end mill tip geometry allows plunge entry as well as lateral cutting passes, making this bit well suited to contour routing, trimming, and slot cutting on laminate and composite panels. Licensed tradespeople and fabrication specialists handling composite materials are the primary installers.

This bit is intended for use on fiberglass panels, phenolic laminates, and similar abrasive non-metallic composite materials. The right-hand cutting direction is compatible with standard CNC routers and handheld router setups. The diamond pattern flute geometry helps evacuate chips efficiently, reducing heat buildup when routing dense composite substrates. It is packaged individually and sold in single-unit quantities, making it practical for job-specific procurement or replacing a worn bit in an existing set.

Key Features

• Solid carbide construction for high hardness and resistance to abrasive composite materials
• Diamond pattern flute geometry promotes chip evacuation and reduces cutting heat
• End mill tip allows both plunge cutting and lateral routing passes
• Bright, uncoated finish maintains sharp edge geometry without coating buildup
• Right-hand cutting direction compatible with standard CNC and handheld routers
• 0.25 inch shank fits widely available router collets and tool holders

Compatibility

Designed for routing fiberglass and phenolic composite materials; fits standard 0.25 inch router collets and CNC router tool holders with right-hand spindle rotation.

Installation Notes

Installation should be performed by qualified machinists, CNC operators, or composite fabrication tradespeople familiar with rotating cutting tool safety. Ensure the router or CNC spindle is fully powered down and locked out before changing tooling. Seat the shank fully into the collet to the minimum insertion depth recommended by the tool holder manufacturer before tightening. Always wear appropriate eye protection and respiratory protection when routing fiberglass or phenolic materials, as generated dust and particles are hazardous.
