The XTREME A071A12 Series represents a high-quality selection of resin bond drum wheels designed specifically for the precision polishing of stone sink holes and curved edges. This Finger B Type tool utilizes a unique square-spot resin pattern to ensure a smooth and stable finish.

Unlike aggressive metal bond bits, our diamond drum wheel provides a softer touch that prevents edge chipping while delivering a brilliant shine on both natural and engineered stones. It is an essential finishing tool for professional fabricators who value high-quality results in every detail of their stone work.

• These drum wheels are built for various stone fabrication tasks that require accuracy and a clean finish. They are primarily used for:

• Sink Hole Polishing: The 25mm diameter is ideal for polishing the internal cutouts of kitchen and bathroom sinks.

• Curved Edge Finishing: Excellent for smoothing internal radius edges and tight curves on countertops.

• Material Versatility: Superior performance on Natural Stone like granite and marble, as well as Engineered Stone like quartz.

• Wet Use Performance: Optimized for wet use to keep the resin bond cool, which prevents stone burning and extends the life of the diamond drum wheel.

• Machine Compatibility: Suitable for use with radial arm polishers or professional handheld stone routers.
