Cool, Reliable Grinding for Zirconia, e.max, and Porcelain
Arctic Grinders are diamond-infused ceramic grinders designed to handle everyday ceramic adjustments with speed and precision. Their durable construction and smooth-cutting performance help dental labs contour and fine-tune zirconia, lithium disilicate, and porcelain without overheating or chipping. Available in coarse and medium grits, Arctic Grinders keep you moving through every case—without sacrificing control or quality.
What Makes Arctic Grinders Different?
Arctic Grinders are built with a diamond-infused ceramic structure that stays cool and sharp during extended use, reducing heat and preventing clogging. They cut cleanly under pressure, minimizing stress that can lead to microfractures and compromised ceramic strength. With coarse and medium grits available across multiple shapes, Arctic Grinders deliver dependable grinding power for labs that need results they can count on.
Optimized for High-Performance Ceramics
Arctic Grinders are engineered to handle the challenges of today’s high-performance materials – like multilayer zirconia, lithium disilicate, and feldspathic porcelain. Their diamond-infused ceramic construction provides fast, pressure-responsive cutting while minimizing heat, surface stress, and microfractures. Arctic’s precise, clean cutting performance helps maintain anatomical detail and structural integrity across a wide range of ceramic restorations.

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.
