If you do a lot of heel check grinds this is the attachment for you. It is also useful for notching pads for clips, beveling the inside web of shoes and touch up of clips. It has a 40-grit Ceramic abrasive that does an excellent and efficient job and is long lasting.
A couple quick notes important to mounting the disc properly. It has a 5/8″ arbor so it fits perfectly on grinder shafts of 5/8″. However, you need a spacer to keep it far enough from the housing to be able to tighten. That spacer will be ¾-1″ long for most grinders. Most importantly, it is directional, meaning you can only mount it properly going in one direction. There is an arrow on the label indicating the direction and it should match the direction your grinder shaft is turning. Be sure you check this before using it. If it is mounted in the wrong direction the disc will not work and will be damaged very quickly.
3/4″x1″ spacer needed. 
Mount in right direction. 
Ready to work.
