The short wiper inserts can generate greater tool pressure than the corner radius inserts. Use the radius inserts to maintain greater visual consistency. Use the wiper inserts for a smoother measurable overall finish.
Ideal face milling engagement (width of cut / Ae) is generally 60%. Reduce to 30-40% for harder materials like heat treated steel. When taking full diameter cuts, reduce depth of cut (Ap) to help reduce tool pressure.
Use coarse-pitch versions when taking a full-diameter cut or when long-reach tool holders are required, or when machining on lighter-duty machine tools (CAT40, HSK63).
Maximum recommended tool diameter for lighter-duty machine tools is 2.0” unless very light cutting is being performed. Wiper inserts are not recommended when machining on lighter duty machines with cutters larger than 2.0”
Technical Considerations
Load inserts with the same cutting edge to minimize runout. See the insert face for ID marks.
Thoroughly clean pockets and inserts at each indexing operation to increase cutter accuracy and achieve maximum tool life.
Thoroughly clean the pocket walls and insert sides with each index to assure even wear and good surface finish.
Insert screw is a Torx Plus size 20IP / TP-20 (wrench not included).
