Cool running. Long lasting.

Arctic Grinders deliver a consistent but gentle grinding action that generates a minimal amount of heat, helping to prevent fractures and chipping. This control assures the efficient and safe removal of material, leading to a perfect finish. Arctic Grinders are outlasting the competition and quickly becoming a lab favorite among technicians.

Arctic Grinders offer a confident expectation of excellence. Choose your shape, select your grit, and get back to the grind.


All types of zirconia – high strength, high translucency and more. Lithium disilicate pressable ceramics like e.max and LiSi. Conventional feldspathic ceramics.


Arctic Grinders are perfect for any ceramic task where grinding is required. They deliver steady and gentle grinding to thin out margins, reduce sprue and connector points or refine anatomy. All without the need for water cooling.


Your project is unique with different requirements. While an aggressive approach requires a coarser grit, a medium grit (our most popular choice) is a perfect start for any work.


Arctic Grinders are designed to keep your restorations cool while keeping the grinding easy. They deliver up to 5 times the life of other brands, while their increased edge stability ensures a smooth cutting action.
