What’s up with the woodshop crew? I’m here to discuss cold saw blades . These blades are handy for cutting ferrous and non-ferrous materials at low speed – from steel to aluminium alloys, they slice it all.

But what makes them truly special is the tooth design. See, the teeth aren’t just for chewing – they’re engineered to rapidly whisk heat off to the chips. This constant cooling keeps temperatures nice and regulated for the blade and workpiece. No burning, sparking or discoloration from excess warmth.

Being able to cut at lower RPMs while avoiding overheating is a huge plus. Your parts come out shiny and burr-free instead of roasted. In addition, the saw and motor stay happier too without all that extra thermal strain. Win win!

Proper technique is key to smooth sailing and long blade life.

First things first – let the blade work for you. Don’t force it or rush the cut, just let those teeth do their thing. Forcing grits me down fast.

Speed control is also crucial. Know your material – low RPM for brittle stuff, faster for tough alloys. Check manufacturer recommendations to dial it in.

Cleaning and lubing the blade regularly is important too. Keeps friction low and chips rolling off smoothly. A dirty mess disrupts your flow for sure.

Speaking of heat, use coolant if possible for extra thermal control. Chilled blades = chilled cuts and a way happier tool. Always remember the guard too! Those rotating teeth are no joke so keep them covered if you’re just setting up.

On average, a quality cold saw blade can rip through 800 to 1000 cuts before fully retiring. That’s a good chunk of work from one tool. But even better – with regular sharpening you can usually get 30 to 40 touch ups out of them! Resharpening extends life way past initial estimates.

Things like material hardness or saw alignment absolutely affect lifespan too. Notice wear earlier than normal, it’s grind time.

Sharpening cost mainly depends on blade size and tooth count. The bigger and more teeth, the pricier to refine the edge. But always cheaper than full replacement.

And don’t forget when teeth get bent or broken, it’s swap out time no matter what. At that point the sharpener may charge extra for repairs.
