Cutting wheel for hard sheet resins and dual laminates Cutting surface on edge that contacts the plastic material Fits most slow speed handpieces; no adapter required High-quality construction; precise clean cuts in sheet material For Pro-Form thermoplastic and dual laminate tray materials Quantity: 1 per Each Keystone Pro-Form Wheel Saw is used for cutting hard sheet thermoplastic resins and dual laminate sheet materials during the fabrication of thermoformed dental appliances, custom trays, occlusal splints, athletic mouthguards, vacuum-formed retainers, bleaching trays, and other appliances produced by thermoforming hard and dual-laminate sheet materials over dental models where the wheel saw provides a precise, controlled cutting instrument for trimming the thermoformed appliance away from the model and trimming the appliance borders to the desired outline form after the thermoforming and cooling cycle is complete. The wheel saw format provides a rotary cutting wheel mounted on a mandrel that fits standard slow speed handpiece connections, delivering the rotating cutting edge directly at the sheet material contact point during trimming to produce clean, straight cuts through hard acrylic sheet resins and the combined layers of dual laminate materials that standard lab scissors, scalpels, or burs are less suited for cutting cleanly and efficiently.Hard sheet resins and dual laminate thermoplastic materials including materials such as Pro-Form Co-Polyester, hard EVA, and co-polymer dual laminates require a cutting approach capable of penetrating the full thickness and hardness of the sheet material cleanly at the trim line without cracking, fracturing, or delaminating the material at the cut edge during trimming. Dental laboratory technicians, orthodontic assistants, and dental assistants who fabricate thermoformed appliances from hard sheet and dual laminate materials as part of their in-office or laboratory appliance fabrication program find Keystone Pro-Form Wheel Saw the slow-speed handpiece-compatible cutting wheel for their active hard sheet thermoplastic appliance fabrication program. ? Keystone Pro-Form Wheel Saw is sold as a single-unit cutting wheel instrument for use with slow speed handpiece systems standard in the dental laboratory and dental office laboratory setting, providing the individual cutting wheel component that mounts directly into the slow speed handpiece latch-type chuck or mandrel connection for immediate chairside or laboratory use during thermoformed appliance trimming. The wheel saw is designed specifically for use with the Pro-Form line of hard sheet thermoplastic materials and dual laminate thermoforming sheets available from Keystone Industries, providing the matched cutting tool for the hard material formats that exceed the cutting capacity of standard laboratory scissors or scalpel blades during appliance border trimming. ? The Keystone Pro-Form Wheel Saw works through its circular cutting wheel construction where the cutting surface is positioned on the outer edge of the wheel that contacts the sheet material surface during the cutting stroke, delivering the rotary cutting action directly at the trim line as the clinician or technician guides the handpiece along the desired cut path across the sheet material surface.The rotating edge penetrates the full thickness of the hard sheet resin or dual laminate at the contact point progressively during the cutting stroke, producing a clean cut line through the material without requiring excessive pressure that could crack or delaminate the sheet material at the trim edge. Fitting most standard slow speed handpieces means the wheel saw integrates into the existing slow speed handpiece available in the dental office or dental laboratory without requiring a specialized cutting handpiece for hard sheet material trimming. ? Orthodontic assistants who fabricate in-office thermoformed retainers, Essix appliances, and bleaching trays from hard sheet thermoplastic materials find the wheel saw provides more controlled and precise border trimming than scissors or burs for the harder material gauges that resist clean scissor cutting at the appliance margins. Dental assistants who fabricate custom impression trays and vacuum-formed splints in the office dental laboratory find the wheel saw a reliable trimming instrument for hard sheet and dual laminate tray materials. ? Keystone Pro-Form Wheel Saw gives dental practices and dental laboratories a high-quality rotary cutting wheel for precise trimming of hard sheet thermoplastic resins and dual laminate materials during thermoformed appliance fabrication, with the cutting surface at the wheel edge for direct material contact, fitting most standard slow speed handpieces for in-office and laboratory use.
