TOROID / BUTTON CUTTERS Single-Sided Toroid Series High-performance Toroid cutters are available with standard ground or CNC-pressed RHINO-CARB™ single-sided inserts. Pressed Toroid Inserts (old versions for comparison) Dapra’s RHINO-CARB high-performance inserts are designed for very aggressive metal cutting and long tool life. SINGLE-SIDED “T” inserts have a strong, negative reinforced cutting edge for steels, irons and hard milling. S tronger cutting edge for heavier chiploads, greater shock absorption and longer tool life (old Left to right: T, N, D versions for comparison) P ositive top rake for reduced cutting forces and lower torque Fancier “cutaway” style “D” inserts have a high-positive cutting edge for stainless steels, high-temperature alloys and gummy materials. Thicker inserts for greater strength and enhanced heat absorption capabilities Left to right: T, N, D Fancier “cutaway” style “N” inserts are more positive than the “T” edge, but stronger than “D.” Fancier “cutaway” style Our Toroid series includes TWO high-performance inserts to maximize the versatility of your Toroid cutting tools: Match the insert R value to the designation on your cutter body. Each R value = 1/8” of insert dia. Button Inserts RPMH RDCH & RXCH Octagonal Inserts

Round inserts have a strong cutting edge, making them an excellent choice for many applications, including: • Pocketing • Semi-finishing • Face milling • old cavity and core roughing M • Roughing of complex part contours • Helical interpolation (larger diameter hole making) TOROID / BUTTON CUTTERS See chart on page 72 for technical help on optimum feeds for button inserts. 8-sided geometry is excellent for general face milling. 45˚ lead angle provides increased feed capacity for: • Face milling • Profiling • Helical interpolation • Chamfering Each of the 8 usable edges comes with an...
