Accupro 71176879 Diamond Pattern Router Bit Solid Carbide

Product Description

The ACCUPRO 71176879 is a solid carbide diamond pattern router bit designed for cutting and routing fiberglass materials. It features a 0.25 inch cutter diameter, a 1 inch length of cut, and a fishtail point end type that helps reduce delamination and fraying at entry. The bit runs with a right-hand cutting direction and ships with a bright, uncoated finish, leaving the carbide substrate exposed for direct material contact. At 3 inches overall length with a 0.25 inch shank, it seats in standard collets found on most router tables and CNC spindles. Fabricators and composites shops working with fiberglass panels, laminates, and similar non-metallic sheet goods will find this bit sized for detail routing and profiling passes.

This router bit is suited for fiberglass fabrication work in production and job-shop environments. The diamond pattern geometry helps clear chips away from the cut zone, reducing heat buildup that can cause burning or delamination in composite materials. It is appropriate for use on handheld routers, router tables, and CNC routing machines where a 0.25 inch shank collet is available. Typical applications include panel trimming, slot cutting, and profile routing in fiberglass and similar reinforced composite sheets.

Key Features

• Solid carbide construction for durability and wear resistance in abrasive fiberglass cutting
• Diamond pattern geometry assists chip evacuation and reduces heat buildup
• Fishtail point end type minimizes delamination and surface fraying at entry
• Right-hand cutting direction compatible with standard router spindle rotation
• Bright, uncoated finish on solid carbide substrate
• 0.25 inch shank fits standard collets on handheld routers, router tables, and CNC machines

Compatibility

Designed for use with fiberglass and similar composite materials. Compatible with any router or CNC spindle accepting a 0.25 inch shank collet.

Installation Notes

Installation should be performed by a qualified machinist or fabricator familiar with router tooling. Ensure the router or CNC spindle is fully powered down and locked out before inserting or removing the bit. Insert the shank fully into the collet to the recommended engagement depth and torque the collet nut according to the machine manufacturer specifications. Inspect the bit for chips or cracks before each use and do not operate above the router or machine speed rating for this shank diameter.
