36h Continuous Cutting Aluminum 1/4 Shank Router Bits: K20 Performance Carbide CNC O Flute Spiral Upcut End Mills for ACP, Acrylic, PVC , HDPE & Plastic, Wood 1 Inch CL, 2 1/2 OVL

Engineered for workshops and CNC factories this single flute router bit solves interrupted processing and low-precision pain points. Crafted with 0.3µm ultra-fine K20 carbide, it maintains stable 48-72h continuous cutting (adjusted by working conditions), reducing tool changes and production downtime. It excels in soft metals (aluminum, copper) and sheets like acrylic, HDPE, wood, PVC, plexiglass, ACP, ACM. With ±0.05μm industrial precision, it delivers burr-free finishes for groove cutting, shallow cutting, mortise slots, cutoff and hole machining—ideal for high-precision parts production. The 25°+28° dual-angle spiral chip evacuation system prevents adhesion on soft materials, keeping cutting smooth and reducing cleaning time. Its 1/4 inch shank, 1 inch cutting length and 2-1/2 inch overall length fit most CNC mills, hand routers and engraving machines with 1/4 inch collets, versatile for diverse scenarios. Balancing durability, precision and efficiency, it’s a reliable choice for both small-batch crafting and large-scale industrial production.

• 36-72h Ultra-Long Continuous Cutting: Crafted with 0.3µm ultra-fine K20 carbide, this tool achieves 36-72 hours of non-stop processing, depending on actual working conditions—ideal for high-efficiency batch production
• Cuts Through Various Materials As Easily as butter: Perfectly suited for soft metals (aluminum, copper) and a wide range of sheet materials: acrylic, plastics, HDPE, wood, PVC, plexiglass, ACP, ACM, etc
• Industrial-Grade ±0.05μm Precision Tolerance: Features a tight ±0.05μm precision range to deliver flawless finishes for demanding tasks: cutting groove, shallow cutting, mortise slots, cutoff operations, and hole machining. Ideal for high-precision parts processing that rejects any margin of error
• Equipment Used: single flute router bit, 1/4 inch shank, 1 inch cutting length, 2-1/2 inch overall length, suitable for CNC milling machines, hand routers, and CNC engraving machines with a 1/4 inch collet
• 25°+28° Spiral Chip Evacuation System: Dual-angle spiral geometry boosts chip removal efficiency, eliminating chip adhesion during processing of soft materials (aluminum, acrylic, etc.). Reduces downtime for cleaning and ensures smooth, uninterrupted cutting
