Diamond hole saw

[monocus]

remember you get what you paid for-if it is for a one time use then no problem-but if you are going to be doing multiple cuts i would go for a more expensive one-you also have to look and see if it isn't warped-i bought a dewalt (really crappy company now)6 " hole saw and it was off center by 3/8 of an inch.at the same time i bought a set of diamond hole saws at summit tools(8 different sizes) for around $80 and they have worked out fine-but i wouldn't use them more than 4 times before replacement.the average diamond holesaw runs about $80
