The 2 quarter round Trapezoid PCD is an excellent choice when removing medium/heavy coatings. The design and positioning of the PCD with an aggressive diamond segment acting as a stabilizer and depth guide scrapes the thickest of coatings aggressively and follows with a conventional grind all in one pass. These PCD's are directional specific and come in a RIGHT and LEFT orientation. 

•••IMPORTANT: If you run a rotary machine with counter rotating heads, be sure to get 1/2 clockwise and 1/2 counter clockwise PCDs when you order.
