ISO ANSI Inserts Like metric and imperial measurements standards the U S has its own tool insert classi ?cation system they are called American National Standards Institute ANSI designations All of these ANSI classi ?cations can be converted to the International Organization for Standardization ISO classi ?cations but this guide includes both for easier selection ? Cutting Tool Designations Cutting tools are easily identi ?ed by their designation which is universal between ISO and ANSI and in the machine shop tool slang often refers to the insert shape which is also available in the tool designation Examples and explanations of designations are available at the start of each section ? Right-Hand vs Left-Hand vs Neutral Right-hand tools are the most commonly used because they can be used for most turning applications including making shoulders on the front of the workpiece Left-handed tools are typically chosen for back turning and making sharp shoulders on the back of the workpiece Neutral tools are ideal for complex pro ?ling thanks to their narrow tips ? Insert Shapes There are a variety of insert shapes available but the general note is use wider inserts for simple geometry and roughing passes since they have more durability than a more narrow cutting tool which is needed for complicated or intricate parts ? Chip Load Chip load refers to how far the cutter moves with each rotation of the spindle All of the relevant information for this can be found in the insert ? s designation with the workpiece ? s material in mind We understand how confusing cutting tool selection can be for beginners and our Wisconsin-based technical support team is ready to answer any lathe-related questions For more information about these products or to view lathe tooling packages visit Tormach com TORMACH COM Table of Contents Turning Tools Boring Bars Turning Boring Inserts Grooving Parting Tools Grooving Parting Tool Inserts Threading Tools Threading Tool Inserts CTURNING TOOLS Turning Tools Turning tools are one of the most commonly used tools and can be used for roughing facing pro ?ling and ?nishing work on the exterior of a part T Clamping System C Insert Shape S Screw Clamp C M Multi-Lock D R S T V W L Clearance Angle B Straight D Straight F O ?set G O ?set J O ?set - K O ?set L O ?set - M Straight S O ?set V Straight Side Cutting Edge End Cutting Edge N Insert Rake Angle B C N R Hand R Right - - Shank Height Insert I
