What is Blade Peening?
Have you found your blade isn't cutting as well as it first was? Here are some tips, tricks and clips to help you extend the life of your blade.
After a blade has been used for some time, the blade will wear the corners of the cutting surface and may cause a narrow “kerf” that the blade does not have sufficient clearance and binds in the cut. This will happen more often when making deep cuts.
Solution: Remove the blade from the saw arbor and carefully swedge the rim with a light ball peen hammer. Strike the rim straight on with light stroke, being careful to keep the hammer square and centered. This will spread matrix and the diamond cutters, making the kerf of the saw wider that the supporting blade plate, giving it relief in the cut. The amount of swedge put into the blade is only a few thousands of an inch and should be applied so the spread is equal on both sides of the blade. Care must be taken to not harm the matrix or distort the blade. After this process has been completed, the saw rim can be dressed with a large whetstone to knock down any points that are too high. Cutting a brick or old grinding wheel after this process will also help even up the blade.
