When starting a cut, don't just ram the blade in at full speed.
Drop your feed rate to about 50–60% of normal. Keep it there until the blade is fully engaged-usually around 10 to 15 mm into the workpiece. This slow entry helps stop the blade from wandering and prevents those first few teeth from chipping or grabbing too hard. Once you're past that initial depth, you can bring the feed back up to your regular cutting rate.
The exit is just as important.
When you're nearing the bottom of the cut-say, the last quarter or so-reduce the feed by about 30%. You can do this manually or let the machine do it automatically. Why? Because as the blade starts to break through, the remaining material gets thin. If you keep pushing hard, the teeth can suddenly snatch and pull through, often ripping off the tooth tips. That's a fast way to kill a good blade.
By backing off, you let the blade ease out smoothly instead of popping through under full pressure.
Between entry and exit, run your normal parameters:
the right blade speed, consistent feed, and enough coolant if the material calls for it. Always match your blade pitch to the material thickness-generally you want three teeth in the cut, but not so fine that you overload the gullet.
In short: start soft, stay steady in the middle, and ease off at the end. These small adjustments don't take much time, but they make a real difference in blade life and cut quality.
