2Pcs 5mm Cutter DiaSolid Carbide Spiral Upcut Engraving Cutter Coating Single Flute Mill Carving Milling CNC Router Bit for Acrylic Plastic PVC ABS NylonF 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 chip evacuation: Single flute O-flute upcut spiral design enables non-clogging rapid waste removal, keeps operating temperatures low to prevent thermal failure. The mill cutter bit set realizes high-speed, high-performance milling, perfect for sign making and furniture cabinetry applications.
• Solid micro-grain carbide construction: Special low-friction Nano coating eliminates tool adhesion in machining.High-density tungsten steel ensures superior edge retention during extended machining of Acrylic, PP, PVC, ABS, Nylon, MDF, hardwood and resins. Prolonged tool life of the engraving carving accessories satisfies hobbyist craft and professional desktop milling project demands.
• Mirror-polished flute pathway: CNC grinding technology reduces friction coefficients for vibration-free operation and minimal radial runout. Delivers a smooth finish on plastics and wood, eliminating manual sanding and deburring, ideal for high-precision 3D carving and sign making requiring premium surface quality.
• CNC Compatibility: Precision-ground shank with ISO-standard tolerance ensures high-concentricity fitment in ER collets, standard router chucks and spindle accessories. Compatible with most desktop CNC routers, engraving machines and hobbyist craft setups
