SIERRA Resin-Filled Diamond Cup Wheel – 4 in., Coarse Grit
SIERRA Resin-Filled Diamond Cup Wheel – 4 in., Coarse Grit
The SIERRA Resin-Filled Diamond Cup Wheel is a 4 in. coarse-grit diamond cup wheel for grinding and shaping stone.
Resin-filled means the gaps between the diamond segments are filled with resin, so the wheel presents a near-continuous face instead of open segments. That is what stops it gouging and is why it leaves a smoother surface than an open turbo cup wheel of the same grit. Coarse is the fastest-cutting of the three grades offered here – coarse, medium and fine – and is the one to reach for when there is real material to remove. The grit number behind 'Coarse' is not published, and neither is the mounting thread or a maximum RPM.

Who Is This For?
Fabricators taking down saw marks, levelling a mitre or shaping an edge, where the priority is removing material fast and a finer wheel would only load up. Follow it with the Medium and Fine grades in the same line rather than jumping straight to polishing pads. It is not a wheel with a published rating for sintered material: for Dekton, porcelain and ultra-compact use the Diamax Cyclone Ultra Cup Wheel – 4 in., Coarse 30, which states the material it is built for.
Frequently Asked Questions
What does resin-filled mean on a cup wheel?
The spaces between the diamond segments are filled with resin, giving a near-continuous grinding face. It resists gouging and leaves a smoother surface than an open-segment turbo cup wheel.
When should I use the coarse grade rather than medium or fine?
When there is material to remove – saw marks, a high mitre, a rough edge. Coarse cuts fastest of the three grades; medium and fine refine what it leaves.
What size is this wheel?
4 in.
Which 4 in. cup wheels in this catalogue publish a grit number?
The Diamax Cyclone Ultra Cup Wheel – 4 in. is listed as Coarse 30 and at 50 grit for the medium, both for Dekton, porcelain and ultra-compact.
