Blade Teeth Selection Advice and Welding Joint Comparison
How to Improve Life
- Blade installation is the first step, make sure teeth is shown outside the guide, and blade strip is clamped tightly inside the guide.
- Teeth direction should be the same with the direction of wheel rotation, twist the blade from inside to outside if teeth direction is opposite.
- Running-in is required when blade cuts metal for the first time. It's important for blade life. During running-in, cutting speed should be 1/3 of normal speed, feed should be 1/4 of normal feed. Usually, after the blade cuts the first several pieces, like 5-10 pieces, adjust cutting speed and feed gradually to normal speed according relative parameters and your metal.
- Blade tension will be different for differnt wide blades, as time goes on, blade tension will be reduced by the bandsaw and blade stretch, make sure the blade is correct tension, our recommended blade tension is 300N/mm2.
- Coolant will be useful to cool and lubricate blade and teeth during cutting, better coolant could avoid overheat on the teeth of the blade, and reduce friction between the blade and the metal you cut.
- Teeth selection is also important, here are our experience:
- big variable teeths (like 3/4TPI, 4/6TPI, 5/8TPI) are for cutting ferrous solid rod with big diameter;
- big constant teeth (like 6TPI) is for cutting ferrous solid rod with small diameter;
- big variable teeth (like 6/10TPI) is for cutting aluminum, copper, brass etc and other non-ferrous metal;
- middle variable teeths (like 8/12TPI, 10/14TPI) are for ferrous thick tubing, profile, sheet, plate etc;
- small constant teeth (14TPI) is for general purpose;
- small variable teeths (like 12/16TPI, 14/18TPI) is for ferrous thin tubing, sheet, plate, profile etc;
- small constant teeth (24TPI) is for ferrous thin tubing, plate, sheet etc, don't cut non-ferrous metal, like aluminum etc.
Welding Joint
We weld blades with high performance welding machine to make sure welding joint looks perfect.
Teeth Direction
Default teeth direction is rightward, if you want leftward direction, please twist the blade from inside to outside.
Original Package
Brand new with original package for this blade with tips behind blade pacakge to help customers.
Metalworking Type
Bi-metal blade is designed for metalworking, ideal for metalworking craftman, blacksmith, mechanic etc.
Compatibility
Accurate length with high performance, compatible with most bandsaws with more choices on teeth pitch.
Ideal DIY Tools
Bi-metal type, M42 grade, 8% cobalt with 2% tungsten, much more fatigue resistant and durable on metal.
Blade Life
Spring steel backer strengthens blade life, hardened edges to cut metal straightly with ease, blade works with high performance.

I was quite happy the minute I opened the Amazon box.Impressive manufacturer's packaging, well protected cutting teeth with rubbery seal on the teeth.Perfect fit and great quality.I think atvthat price, it is a bargain.

The fit is spot on. I like the blade covers. They make handling the blades easier and safer. The weld joint is nearly invisible and has no effect during use. They are a tiny bit thicker than my old brand, but I don't know yet if that will yield extra durability. I am getting improved cutting speed.

I dint know what people are doing with them to wear them out so quick. They have been working just fine for me. Can't say if it last longer or not than the original. Haven't worn one out yet. I've made about 20 cuts on 1inch thin steel wall tubing.

They stay sharp much longer than others I have had. They are also quite flexible and won’t break right away when I slightly twist them during a tight cut.

I like this blades so far. Is is thicker than the original dewalts blades if I'm not mistaken. At least looks thicker for the one I removed from the machine. Being a thicker blade it deform less when cutting thick metal. Also the way they come in small roll and can be put away in a drawer.Will by again for sure.

Moi je me sert de ses lame pour couper le métal je fabriques des remorques (tirailleur) 4x8. Et aussi 6x10 ses lame son génial sa coupe plus que des disques avec une meule (grander) je recommande pour des gros projet et pour les petits moi personnellement j’espère que se vendeur va rester sur Amazon noter bien en plus. Il respecte le délai de livraison . Si je pourrais donner 10 étoile je le ferai . Moi personnellement je le cote à 10 âï¸âï¸âï¸âï¸âï¸âï¸âï¸âï¸âï¸ðŸŒŸ
