PMX05-02800-10N1 PRECIMASTER HOLDERS

Precimaster™ Plus is a modular reamer system that boosts reaming speed, stability and versatility for more precise, cost effective hole production. Building on the success of the original Precimaster™, the system features an innovative high precision connection, solid carbide disposable heads as well as common holders for blind and through hole applications. Such enhancements enable size tolerances held to between 15 and 25 microns and surface finishes of Ra. 4 to Ra. 8. The system's patented connection ensures reamer head exchanges are fast and easy with repositioning repeatability and run out of under three microns. A special three vertical drive pin design enables the connection to handle high levels of transmissible driving torque. Internal axial clamping forces draw the reamer heads up into the system shanks, creating a strong interface that maintains high precision. Precimaster™ Plus uses solid carbide disposable heads in diameters that range from 10 to 60 mm and mount to four standard shank sizes. Shank lengths are available in short, medium and long options to accommodate restricted clearance situations, common hole depths and up to 10xD, respectively. Solid carbide heads, when compared with traditional brazed tip technology, allow for an increased number of cutting teeth on the same head diameters for up to 30% faster feed rates. Solid carbide also extends tool life by up to 30%, delivers increased stability for tougher materials and makes for a more cost effective system. For chip control and management, Precimaster™ Plus reamer shanks can apply different types of flushing for both blind and through holes. Tool body coolant outlets in the front force the chips up along the head flutes and out the blind holes, while standard through tool coolant blasts the chips forward and away from the tool for efficient through hole reaming. Precimaster™ Plus features three lead geometries for universal, aggressive feed and fine finish operations as well as five reamer head grades, involving coated and uncoated carbide and cermet, to ensure optimized performance in all workpiece materials.
