S7 HIGH PERFORMANCE END MILLS SOLID MILLING CUTTERS INTRODUCTION We have expanded our S7 assortment of multi-application high performance cutters for use on both CNC and conventional machine tools. The new additions support most common operations, such as slotting, plunging, contour milling, ramping and copy milling in various materials, including medium strength steels, stainless steels and super alloys. FEATURES & BENEFITS • The four-flute cutters have a specific tooth design for • A long version for higher depth of cut. improved chip evacuation. • NRA profile to break swarf into manageable smaller • An unequal helix option for chatter free machining pieces, helping to reduce spindle load and increase and excellent surface finishing. metal removal rates. • Positive rake angle for a smooth cutting action, • Neck recess feature to avoid contact with the wall in reducing the risk of work-hardening. shoulder operations. • AlCrN and Titanium Silicon Nitride (TiSiN) coatings for longer tool life; enabling higher cutting speeds and increased heat resistance, making them ideal for dry machining.
