Saw blade for cutting mdf

[dr_peeb 10+ year member]

But you see, that's quite frankly a hopeless bit of reasoning. Why would you spend money on something that you KNOW will end up costing you more money and effort? If you drop 50-60 on an outstanding carbide or diamond tipped blade with 60T, you won't be changing that blade for years. If you drop 25 on a cheap steel blade, you'll be changing that blade after a few boxes because even if it's still sharp, it'll likely be warped or otherwise bent.

Are you saying $25 blades are a completely useless waste of money, or MDF is so hard on blades you have to buy a $60 to cut it? I disagree with both.

60-80 tooth carbide blade is best, the glue used to hold the mdf together when cut is the death to your blades, so i wouls speand the money on a good blade - and keep it clean and waxed like suggested eailier, it does make a difference on how easy the wood cust.

I think I only paid $30 for my Diablo blade (I may have used a 25% off coupon though) and it hasn't gone dull after about 6-7 sheets of MDF being ripped up as well as quite a bit of 1/4" plexi that I've cut. You don't have to spend a lot of money on a blade that will work well. My stock craftsman blade was actually pretty decent and cut well enough for like 10 boxes before I replaced it.

I said neither; I was using examples to make my point. I said that just buying a cheap wood blade is a completely useless waste of money for a box builder, because if you spend good money on one that will last for years, the blade will pay for itself before you realize it. You could cut MDF with a hand saw if you had to, but again, that saw will be hopeless afterwards due to the resins that MDF is made with, and as such you'll end up buying a new saw if you want to have the cutting power of the first time.

I was assuming OP just wanted to cut some MDF, whereas you're assuming he wants to invest in a long-term saw blade.

Sounds like we need to know more about his plans to advise whether or not he should spend the extra 35-40 bucks on a blade that will last a while.

By the way, I'm using my Home Depot's prices.

I would just assume that if he needs a saw blade, then he has a saw, and is consequently beginning to build boxes, thus, it makes sense to get a buy-and-forget blade. But I've been wrong before //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

No. I have a brush cutter that takes old saw blades, they work great for that //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
