Komet USA has introduced its Komet H4MCXXL crown cutter, which is designed to cut through crowns and bridges constructed of commonly used alloys and titanium.
The cutter is also recommended for use on veneers fabricated of low-fusion ceramic materials and porcelain-fused-to-metal crowns, according to the company.
Like the other Komet H4MC cutters, the H4MCXXL includes the manufacturer's D-toothing feature, which allows rapid and efficient cutting of crowns and bridges made of conventional metals. Large chip spaces permit quick chip removal and prevent clogging, especially when cutting soft alloys with gold content, according to Komet.
The new, 8.0-mm-long version completes the range of the H4MC crown cutter series, which also features cutters with regular (2.0 mm; H4MC), long (3.5 mm; H4MCL), and extra-long (5.0 mm; H4MCXL) working ends. The instruments can be used in electronic micromotors, as well as air-driven handpieces at an optimal speed of 160,000 rpm with sufficient coolant, Komet noted.
