4Pcs 1/8 in Cutter Dia,Solid Carbide Engraving Cutter Single Flute Upcut End Mills Coating Single Flute Carving Milling CNC Router Bit for Acrylic Plastic Hardwood PVC MDF Aluminum Plates

Engineering Solution for High-Friction MillingStandard multi-flute bits fail when machining plastics and composites because they cannot evacuate waste fast enough. This leads to heat buildup, melted material, and eventually, tool fracture. The WKSTOOL Single Flute Spiral Upcut is the professional solution to these mechanical failures. By utilizing a single, deep-well flute, this bit maximizes the volume of material removed per rotation, keeping the cutting zone cool and the edges sharp.Our bits are forged from solid micro-grain tungsten carbide, providing the rigidity needed for 3D carving and deep-slotting. Whether you are running a production cycle in 1/4" Acrylic or detailed engraving in Hardwood, the mirror-polished spiral ensures that every pass is smooth and every edge is professional-grade.Technical Specifications:Material: Solid Tungsten Carbide (Micro-grain)Flute Count: Single Flute (O-Flute)Cutting Type: Upcut SpiralShank Diameter: 1/8" (3.175mm)Overall Length (OAL): 1-1/2" (38mm)

• OPTIMIZED O-FLUTE CHIP EVACUATION: stop chip welding,engineered with a high-angle spiral upcut geometry to maximize chip load capacity. Ideal for intricate engraving on Acrylic, PP, PVC, ABS, Nylon, MDF, hardwood and Aluminum-plastic panels
• FORGED FROM HIGH-DENSITY CARBIDE: premium solid carbide bar material, razor-sharp edge significantly. more consistent production runs.Faster feed rates and machining capabilities meet strict standards for industrial carving and professional fabrication. Eliminating manual sanding and deburring,ideal for high-precision 52D carving and sign making requiring premium surface quality.
• ULTRA-SMOOTH SURFACE FINISHES: The high-polish spiral flute reduces friction and prevents "chatter" marks on your final part. Special low-friction Nano coating eliminates tool adhesion in machining.nano-hardness of 38 GPa and oxidation resistance up to 600°
• DROP-IN DESKTOP CNC COMPATIBILITY: The universal 1/8 inch (3.175mm) & 4-61mm shank fits perfectly into most desktop CNC routers, machining centers, and engraving planers. Simply swap your old bits and run your existing G-code.
• Cutter Size: 1/8 in Cutter Dia (1/8mm) / 0.98 in Length of Cut (25mm) / 1/8 in Shank Dia. / 1.96 in Overall Length / Right Hand Blade Direction / Flutes:1 / Package：4pcs/set
