SIERRA Resin-Filled Diamond Cup Wheel – 4 in., Medium Grit
SIERRA Resin-Filled Diamond Cup Wheel – 4 in., Medium Grit
The SIERRA Resin-Filled Diamond Cup Wheel is a 4 in. medium-grit diamond cup wheel for shaping and levelling stone after the coarse pass.
Medium sits between the coarse and fine grades in this line and is the grade most edge work actually lives on: it still cuts, but it leaves a surface fine enough that the fine wheel has little to do. The resin filling the gaps between the diamond segments gives a near-continuous face, which is what keeps the wheel from gouging as it shapes. The grit number behind 'Medium' is not published, and neither is the mounting thread or a maximum RPM.
