At the weekend I decided to use this blade to saw a mild steel bearing block into 2 parts. I had already drilled 2 vertical holes through the blocks to take the bolts that will fix the blocks together in use.
I pushed the cutting rate too hard and stalled the mill – the result when I backed off was that a tooth had broken off.
I believe the blade had caught on the edge of one of the holes and stopped dead.
I managed to carry on using the saw and complete the job, but annoyed at my gorilla machining and lack of patience. Also, this is not the first time I have had a carbide tool just sheer this way and break.
