1/4-20 UNC Solid Carbide Thread Mills Milling Cutters Three Tri Form Unified Coated Blind Holemaking Threading Tapping for Aluminum Copper Non-Ferrous Alloys Cast Iron PVC Plastics

1. Achieve Flawless Threads Every Time – Our thread mills are engineered for precision, whether you're working on steels 2. Effortless Chip Evacuation for Faster Work – Ensuring clean, accurate threads in every thread. Clear tooth pattern, .Spend less time clearing debris and more time completing your projects with unmatched speed and efficiency. 3. Built to Last in the Toughest Conditions – Solid Carbide material,the coated precision thread mills provides Fine-Toothed, polished surface,longer tool life. 4. Smooth Operation, Reduced Breakage Risk – Spiral Pointed Tap Series for through hole,The sharp, tapered cutting edges minimize resistance, making threading smoother and reducing the risk of tap breakage. 5. Versatile Performance for Every Project – Suitable for machining a variety of materials,used on CNC Machining(The runout of the equipment is controlled within 0.008mm range.),Ideal for forged products and tempered materials like S48C to S55C at 45 to 55HRC.

• Versatile Threading Performance:solid carbide thread mills,designed to mill right hand and left hand threading applications. Specially designed for aluminum,copper alloys, brass,Cast Iron,bronze alloys (up to 55 HRC),high-speed thread milling easily and are good for tough jobs in aerospace, automotive, holemaking, and mold die work.
• Precision-Engineered for Accuracy:h6 shank for secure fitment in high-precision tool holders. cuts internal 60° threads,able to cut larger threads of the same pitch.cutting at the first thread ensures non - tapered, highly accurate internal threads.
• Efficient Internal & External Thread Machining:Three forms and helical design reduces tool pressure and deflection resulting in accurate threads,designed to mill right hand and left hand Unified threads for added versatility,The same PRML can process both right and left - hand internal threads via helical interpolation.
• Durability and Heat Dissipation:Ultra-Durable Nano Coating;tungsten steel material, capable of withstanding high-intensity cutting, providing superior heat dissipation even at high speeds.durability and perform optimally throughout the fast threading process
