Chop saw blade

i paid about 500 bucks with the blade. yeah no coolant or nothing. still lasts forever. i use it alot on 2x3 and round tubing

I'm buying this one for my new Makita chop saw that I am getting.

we use a similar diamond tipped blade on our k-12's at work....great at cutting garage doors, cutting cars apart, and cutting into roofs for ventilation....runs at about 10k rpm on the 14" model.....and to sharpen just bury it in some concrete...i thought about getting one for a chop saw but i got a band saw instead
