> 24 hourInstalled this blade on a recently purchased Harbor Freight Metal Band Saw without any problems. I am cutting thin wall mild steel tubing (1/2 to 1” by 1/16” wall) at a slow speed and very little downward force. After installing the blade, I made sure it was aligned vertically and horizontally, so it would cut square. Since installing the blade I have probably made 50 cuts without any problems. The only change I might make is to use a 14/18 tooth blade, because I generally only cut thin wall steel. I would recommend this blade! BTW, the stand is made of 1” sq x 1/16” wall mild steel tubing with wheels, cut with this saw before installing the new blade.

> 24 hourIve had a small machine shop for 13 years that works primarily in aluminum and let me tell you, Ive tried pretty much every brand of bandsaw blade made, and this brand is the one Im using for the foreseeable future. Better price and better construction, on the small horizontal bandsaw, when they eventually break, its NEVER at the weld like others, and on the larger vertical bandsaw they never break, but run so long that they do eventually dull and I replace the blade. They run quiet, and the weld joint is perfect with no space between teeth like some.

> 24 hourThis is an excellent metal cutting blade, works perfect in my Harbor Freight horizontal saw. The original blade the saw came with was a 14 TPI, not bad, but snapped. Replaced it with a US made 14 TPI which was total crap, dulled quickly and snapped. Ive used this bi-metallic blade for about two weeks now, and works perfect. Cuts quickly and smoothly, does not gum up and is a big improvement over the high-carbon blades. This is also pretty thin so it cuts quickly and passes easier in the metal. Excellent quality blade, very good steel, and comes nicely packaged with a plastic guard over the teeth so they dont chip. For the price, I dont think theres any other blade nearly as good.

> 24 hourTeeth durability. Teeth offset on one side dull then cuts very crooked.

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.
