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

Arctic Grinders FAQ
What materials can Arctic Grinders be used on?
Arctic Grinders can be used on zirconia, e.max/lithium disilicate, and conventional ceramics.
What speed should I use when operating Arctic Grinders?
The optimal speed for Arctic Grinders is between 6,000 and 20,000 RPM, depending on the shape, with some shapes having a maximum speed of 20,000 RPM and others up to 30,000 RPM. To ensure effective material removal and prevent damage to the tool or workpiece, it’s best to consult the product label or the chart on our website for shape specific speed recommendations.
What do the measurements on Arctic Grinders refer to?
The measurements on Arctic Grinders include both the diameter (widest part) and the height (length) of the working portion.
Do Arctic Grinders need to be used with water spray for cooling?
No, Arctic Grinders are designed to be used dry and do not require water or a cooling system. They remove material efficiently while minimizing heat buildup when used at the recommended speeds.
What is the best technique for using Arctic Grinders?
For best results, operate Arctic Grinders at the recommended speeds and apply moderate pressure to maintain control. Use a light touch for detailed adjustments, letting the grinder do the work. Avoid prolonged heavy pressure, as it can generate excess heat, accelerate wear, and reduce efficiency.
