Solid Carbide Ball Nose PVD Diamond Coating Graphite 2/4 Flutes Square End Mill Carbide Milling Cutter for Graphite Carbide/Glass Heat Bending Mode/Carbon Fiber Product Description Diamond Coating Graphite Square Milling Cutter These end mills have a diamond or diamondlike coating for machining abrasive material, such as carbon fiber, fiberglass, and graphite. Made of solid carbide, they are harder, stronger, and more wear-resistant than high-speed steel and cobalt steel for the longest life and best finish. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. They have a ball end for milling rounded slots, slopes, and contours. All are center cutting, allowing plunge cuts into a surface. End mills with fewer flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts; end mills with more flutes provide a finer finish and operate with less vibration when run at high speeds. Diamond coated end mills are an economical option for short runs and intermittent use. Diamond-coated end mills are good for long production runs. They run twice as fast as other carbide end mills and last up to 30 times longer. Applications Applications of diamond-coated end mills and diamond-coated drills CVD diamond-coated tools are ideal for the machining of non-ferrous materials. Popular uses of these tools include: Machining Graphite Machining Carbon Fiber Machining Fiberglass Machining Filled Plastics Machining Green ceramics Machining Aluminum alloys Machining Copper alloys Model Flute OD Flute length Effective length Shank OD Overall Lengt Flute Qty D1 L1 L3 D2 L2 D0.4*1*4*2T*4D*50L 0.4 1 4 4 50 2 D0.5*1.5*6*2T*4D*50L 0.5 1.5 6 4 50 2 D0.5*1.5*4*2T*4D*50L 0.5 1.5 4 4 50 2 D0.6*1.5*6*2T*4D*50L 0.6 1.5 6 4 50 2 D1*3*10*4T*4D*60L 1 3 10 4 60 4 D1*3*15*4T*4D*60L 1 3 15 4 60 4 D1*3*20*4T*4D*60L 1 3 20 4 60 4 D1*3*25*4T*4D*75L 1 3 25 4 75 4 D1.5*4.5*15*4T*4D*60L 1.5 4.5 15 4 60 4 D1.5*4.5*20*4T*4D*60L 1.5 4.5 20 4 60 4 D2*6*15*4T*4D*60L 2 6 15 4 60 4 D2*6*20*4T*4D*60L 2 6 20 4 60 4 D2*6*25*4T*4D*75L 2 6 25 4 75 4 D3*9*20*4T*3D*60L 3 9 20 4 60 4 D3*9*20*4T*3D*60L 3 9 20 3 60 4 D3*12*30*4T*4D*75L 3 12 30 3 75 4 D3*9*30*4T*3D*100L 3 9 30 3 100 4 D4*12*25*4T*4D*60L 4 12 25 4 60 4 D4*12*30*4T*4D*75L 4 12 30 4 75 4 D4*20*35*4T*4D*100L 4 20 35 4 100 4 D6*20*4T*6D*75L 6 20 20 6 75 4 D6*25*35*4T*6D*75L 6 25 35 6 75 4 D6*25*40*4T*6D*100L 6 25 40 6 100 4 D6*40*4T*6D*100L 6 40 40 6 100 4 D8*25*35*4T*8D*75L 8 25 35 8 75 4 D8*30*40*4T*8D*100L 8 30 40 8 100 4 D8*50*70*4T*8D*150L 8 50 70 8 150 4 D10*35*50*4T*10D*100L 10 35 50 10 100 4 D10*50*70*4T*10D*150L 10 50 70 10 150 4 D12*50**4T*12D*150L 12 50 50 12 150 4 D12*50*70*4T*12D*150L 12 50 70 12 150 4 Coner Radius End Mill With Diamond Coating Model Flute OD R Flute length Effective length Shank OD Overall Lengt Flute Qty D1 L1 L3 D2 L2 D0.5&R0.05*1.5*5*2T*4D*50L 0.5 0.05 1.5 5 4 50 2 D1R0.05*3*10*2T*4D*50L 1 0.05 3 10 4 50 2 D1*R0.1*3*10*4T*4D*60L 1 0.1 3 10 4 60 4 D1.5R0.1*4.5*15*4T*4D*60L 1.5 0.1 4.5 15 4 60 4 D2R0.1*6*15*4T*4D*60L 2 0.1 6 15 4 60 4 D2R0.2*6*15*4T*4D*60L 2 0.2 6 15 4 60 4 D3R0.1*9*20*4T*4D*60L 3 0.1 9 20 4 60 4 D3R0.2*10*4T*3D*60L 3 0.2 10 10 3 60 4 D3R0.5*9*20*4T*3D*60L 3 0.5 9 20 3 60 4 D3R0.5*9*30*4T*3D*60L 3 0.5 9 30 3 75 4 D3R0.2*12*30*4T*3D*75L 3 0.2 12 30 3 100 4 D4R0.2*13*4T*4D*60L 4 0.2 13 13 4 60 4 D4R0
