Grooving Holders

Grooving or recessing operations, sometimes also called necking operations, are often done on workpiece shoulders to ensure the correct fit for mating parts. When a thread is required to run the full length of the part to a shoulder, a groove is usually machined to allow full travel of the nut. The "Grooving Tool" is used for cutting circular grooves on the inner surface of tubing, and for chamfering hole edges. Two types of rectangular cutters are available, one with a single blade and the other with a double blade.
