HOW TO USE:

1. Safety First: Before beginning any work, ensure the brake lathe is powered off and unplugged. Always wear appropriate personal protective equipment, including safety glasses.
2. Locate Old Insert: Identify the current carbide insert on your Ammco brake lathe’s cutting head.
3. Remove Old Insert: Using the appropriate tool (usually a small screwdriver), carefully unscrew and remove the worn or damaged carbide insert from its holder.
4. Clean Holder: Gently clean any debris or metal shavings from the insert holder to ensure the new insert sits flush and securely.
5. Install New Insert: Take one new Ammco .032″ Negative Rake Carbide Insert from the pack. Position it correctly in the holder, ensuring the desired cutting edge is exposed.
6. Secure Insert: Use the provided screw to firmly fasten the new insert into place. Do not overtighten, but ensure it is snug and stable.
7. Rotate Cutting Edges (Optional): Each insert typically has multiple cutting edges. Once one edge becomes dull, you can rotate the insert to expose a fresh edge before needing a full replacement.
8. Test Cut: After installation, perform a test cut on a scrap rotor or a non-critical part to verify the insert is properly seated and cutting as expected.
