Nice review,, We have been using a Makita 12" Carbide for about 5 years now, the blades will last a long time when used properly, like allow the blade to stop spinning before bringing saw back up after cut, spray alittle WD-40 when starting a cut on a flat section wider than 2" x 3/16 thick, don't force the cut, just common shop sense stuff. I have used 3 blades in 5 years, cutting up hundreds of feet of steel. Also we have found a shop that will sharpen the dull blade for $35. so that helps take the sting out of buying a new blade...LOL
The faster speed of the Bullet blade kinda makes me nervous, should it catch a tooth on something, but it would give a new use to my 14" abrasive saw.
