Komet USA has released its H4MCXL carbide crown cutters in a 014 size, which also has a longer 5-mm working part.
H4MCXL, along with Komet's other carbide crown removers (H4MC [012] and H4MCL [012]), are available with friction grips and have a unique blade design, according to the company. Their pyramid-shaped blade configuration and transversing blade allow dentists to feel their impact when they efficiently cut into metal alloys, titanium, and ceramic veneers, Komet said.
The pyramid-shaped blade design helps prevent blade breakouts and provides increased stability and high resistance to breakage, thus ensuring a smooth operation with little vibration, according to the company.
The "crown cutters have a special D-toothing design that facilities quick and efficient cutting of crowns and bridges made from conventional metal alloys," the company said.
The large chip spaces allow fast chip removal and prevent clogging, especially when cutting soft alloys with gold content, Komet added.
The company recommends that the H4MCXL carbide crown cutters be used in an electric handpiece at 160,000 rpm, but noted that they can also be used in the turbine at 300,000 rpm.
