This .4 wide wheel has corner radius profiles on each side and a flat area in the middle which can be used for neck reduction grinds
.5 mm or .020 corner radius one side
1 mm or .040 corner radius on the other side 320 grit (nice finish)
This wheel is nice when a 1/2 inch wheel is too wide on smaller end mills
that need a little extra reach
180 grit x .4 wide 6-inch neck wheel coarser grit for longer life
Best used on our Tradesman Machinist
