Solid carbide slitting saw & knife

Using the correct cutting speed is an important part of using slitting saws correctly. You must realize that when you exceed the cutting speed with high speed steels, the dulling process can be instantaneous. It isn't you get shorter tool life, you get 'no life'! This can be expensive in time and money because slitting saws usually cost so much you don't have spares. Another problem that happens with slitting saws is that one edge gets dull before the other. This causes the blade to deflect as it cuts. How much it deflects is somewhat a function of the blade's thickness. A common error that can be made is putting a slitting saw on the spindle upside down when they will only cut one way. Look carefully at the direction the teeth are facing. Coolant should be used. It doesn't have to be flooded, but it should be applied liberally to keep the fine teeth from loading up. When cutting a slot that goes into a large hole, it is possible to have the part clamp the saw blade as it cuts through. It usually doesn't cause any serious problems, just stop the spindle and back it out. There is always a question of the best approach to use when cutting a slot with a blade that is less than .060'(1.5mm). You can cut in a series of passes, cut full depth in one pass, or cut straight in. The method to use is up to you, experiment with scrap until you're confident you will not screw up a lot of work.
