CMT Discs
KLINGSPOR is pleased to offer the most efficient and most innovative flap disc ever - the CMT Quick Change Flap Disc. This is a quick-change version of our industry-leading flap discs. The concept is a tremendous breakthrough for the metal grinding and finishing community. Production shops will greatly benefit with even less downtime and an increase in productivity.

How does it work? Simply affix the die-cast backing plate to your angle grinder using a standard locking nut and leave it there. Then the CMT "loadings" are locked into place with a quick turn of the wrist. No tools are necessary to accomplish the task, which only takes seconds. When a new grinding surface is needed or when grits need to be changed, twist the CMT off and put a new one on. No more fumbling with the grinder’s locking nut each time - twist on, twist off.

The CMT also offers an extremely safe operating environment. The fibre-reinforced plastic on the back of the CMT guarantees maximum stability with an approved operating speed of 12,200 max. rpm.

If you have resisted using flap discs in the past for whatever reason, KLINGSPOR’s CMT quick-change flap disc will make you a believer. Discover the ease of use that the CMT has to offer and gain the advantages that this system can bring to your manufacturing process. 

Special “channels” ensure that the CMT is securely locked in place.
