0.2500" (1/4") x 1.00" LOC Diamond Flute Carbide Router, Down Cut, Fish Tail Tip, 1/4" Shank | A284

This 0.2500" (1/4") diamond Flute carbide router bit features a 1.00" length of cut, 3.00" overall length, and a 1/4" shank. Sold individually, this solid carbide router is designed for routing abrasive laminates, composites, and other tough sheet materials where durability and controlled cutting are important.

The diamond Flute down-cut flute geometry is well suited for materials such as FR-4, G-10, fiberglass, carbon fiber, phenolic, laminates, and similar abrasive composites. Its fish tail tip helps provide gentler entry in brittle or layered materials and can help reduce fraying or delamination at plunge.

Because this is a down-cut router, it helps direct cutting forces and chips downward, which can improve top-edge finish and help keep the top surface cleaner in materials where upper-face quality matters. This makes it a strong choice for trimming, profiling, and routing operations where minimizing top-surface chip-out is important.

Typical Applications

• Routing and trimming FR-4 and G-10
• Contour cutting fiberglass and phenolic laminates
• Profiling carbon fiber sheet and similar composites
• Slotting and edge trimming in abrasive sheet materials
• General CNC routing where cleaner top-surface results are desired

Benefits

• Diamond Flute flute geometry for effective cutting in abrasive materials
• Down-cut design helps improve top-edge finish and reduce top-surface tear-out
• Fish tail tip helps provide cleaner entry in brittle or layered workpieces
• Solid carbide construction for rigidity and wear resistance
• Well suited for composite, laminate, fiberglass, and PCB-style routing applications
