AMT Solid Carbide Thread Mills for Aluminum Machining
Solid carbide thread mills for High-speed Aluminum machining. High-speed aluminum machining requires tools that minimize the tendency of Aluminum to stick to the tool cutting edges, provides high surface finish, ensuring efficient chip evacuation and sufficient strength of the cutting edge to absorb the cutting forces.
AMT Cutting Data Uncoated Sub- Micron carbide grade for Aluminum and non- ferrous materials, Stainless Steels and Titanium. K20 Optimized carbide grade for Aluminum, cast iron and stainless steels Cylindrical shank (Weldon shank - upon request) With internal coolant bore Uncoated, smooth cutting edge High thread surface quality Same tool for right hand or left hand internal threads Additional items with cutting chamfer Features
