Product Description

1/2" 3 Flute Carbide Rougher/Finisher, .060" Corner Radius, 1/2" Plain Shank, .625" Loc, 4.250" Reach With Reduced Neck, 6" Oal. Yg-1 Alu-Power Hpc Chip Breaker 37° Helix, Uncoated For Aluminum. What Do You Get When You Add 3-Flutes To The Center, Polished Ultra-Micrograin Carbide, Extra-Large Chip Gullets And A Razor- Sharp Cylindrical Land Design? In Technical Terms, It’S Called The Alu-Power Hpc. In A Machinist’S Term, It’S Called An Extremely Sharp, Highly Durable Milling Monster That Won’T Back Down, Cut After Cut. Yg-1'S Alu-Power Hpc Carbide End Mills Are Built To Handle High-Speed Cutting Without Edge Buildup. Designed With High Spindle Speeds In Mind, They Excel In Ultra High-Speed, High Horsepower Applications Up To 35,000 Rpm. Whether You’Re Running Parts In Today’S Most Advanced 5-Axis Machining Centers On The Market Today, Or In Machines Built Decades Ago, Alu-Power Hpc Makes The Most Of Your Manufacturing Assets. That’S Because It's Unique 3 Flutes To The Center, 37° Helix Design Can Also Operate At Lower Speeds With Higher Efficiency. These Tools Are Highly Effective In Vertical Ramping Up To 20°, Trochoidal Milling Applications, High Speed Peel Milling And Step-Over Plunging Applications. When You Lock An Alu-Power Hpc Into Your Milling Machine, You’Ve Unleashed The Fastest-Running, Lowest Heat-Producing End Mill In The Business. And That Means You’Ve Got The Speed And Sharpness To Take On Not Only The Tough Materials But Also Even More Fragile Mixed Alloy Castings With Ease. Discover The Alu-Power Hpc And Start Pushing Your Productivity Higher.
