Exchangeable inserts allow for work with consistent cutter masses and high precision - optimal for use with templates. No resharpening is needed, and they are immediately ready for use again. The cutting length of 25 mm also allows for milling deeper grooves. Carbide groove cutters with interchangeable inserts cut both at the tip and on the side. They are ideal for deep grooves. Insert milling tools generally have advantages over conventional tools, especially with intensive use: no resharpening, always ready-to-use tools, and a consistently maintained diameter.
