Maximum Durability for Precision Metal Cutting

The Diablo DJT121AF5 3-5/8" 21 TPI Bi-Metal Jig Saw Blades are engineered to redefine performance in medium metal cutting applications. Designed specifically for materials ranging from 1/16-inch to 1/8-inch in thickness, these blades feature an ultra-hardened cutting edge that delivers up to five times the life of standard blades. Whether you are cutting sheet metal, pipes, or profiles, the optimized bi-metal tooth design ensures long-lasting sharpness and durability, making this 5-pack an essential addition to any professional toolbox or DIY workshop. 

Innovation meets efficiency with Diablo's advanced blade geometry. A unique back taper body design promotes fast, clean cuts by reducing drag, while the Perma-SHIELD® non-stick coating minimizes heat build-up and protects against pitch and corrosion. The blades also feature a fast plunge tip design, allowing for quicker and easier plunging without the need for a pilot hole. Equipped with a universal T-shank, these blades offer maximum performance and a secure fit for all combo and most U-shank cordless and corded jig saws on the market.

Key Features

  • Extended Lifespan: Ultra-hardened cutting edge delivers up to 5X longer life than standard bi-metal blades.
  • Optimized for Metal: Specifically designed for cutting medium metals ranging from 1/16 in. to 1/8 in. thickness.

  • Precision Design: Back taper body allows for faster, cleaner cuts with less vibration.

Pro-Tip: When cutting metal with a jig saw, turn off the orbital action (set it to 0). Orbital action is great for wood but can cause metal-cutting blades to bounce, chatter, and break teeth prematurely. For the longest blade life and smoothest cut, use a slow to medium speed and apply a small amount of cutting lubricant to the cut line.

Dog loves it, but it comes apart pretty quick.
Size: One Size
The dog loved chasing it and playing tug-of-war, but it lasted less than 30 days. If the outer rubber portion of cover was thicker, or all canvas material, it would probably last for a few months of rough play. May buy again if I can't find something similar to try.

This is a big ball.
Larger than I thought but still a great toy for a heavy chew pup, easy to toss and won't go under funiture. She has the same ball in a 5 inch size so I know it's quality and will last. Can't wait for Summer, will make a great yard ball.

Second one, first one lasted a good while
We leave it outside in the weather with solid results for our backyard dog, and the dog loves this thing. It's our go to toy for her, ... perfect for kick to fetch, tug of war, hide in the shirt, bump the human leg when it is wet, etc. ;) The first one we used and used and finally it started to show too much weathering, mildew, and finally breaking after like 1.5 years... we have extremely hot and wet weather here. When new though, these balls take a pounding. Our 50 pound dog can play tug of war to the extent we can pick her up while she holds onto the ball with her teeth. The ball doesn't flinch and the dog loves it. Kicking it is fun because you can give it a wallop and it won't go over the fence since the design absorbs a fair bit of the kick energy, but it is still enough for an adult or teen to send it about 1/4 an acre away. What else... oh the dog has a funny habit of finding the one spot that isn't an empty pentagon... as in the plastic is filled in there... and she likes to bit on that part especially during tug of war. I should also mention our dog literally breaks apart and sometimes eats sticks and twigs in the yard, can't be healthy, so a nice diversion is this ball that she will chew on once in a while without destroying it.

Absolutely love this brand of ball for my dog
I end up replacing these every couple years, yep that's right, years. My border collie will grab this ball in his mouth and then kick another ball around. Don't know why he has to have something in his mouth to play soccer, but he is unique. He managed to tear one of these up when he was in his teething stage, but it took him months, and I took it away as soon as he managed to remove a piece of it. Otherwise, we usually lose these much more often than them getting destroyed through constant chewing, and I suspect heavy weathering outside for an extended period of time. Nowadays he doesn't chew on rubber nearly that often, he has developed his own picky preferences. This ball is his must have for playing around. He loves to drop it down the stairs and play fetch with himself. It's easy for him to grab, it isn't heavy so we don't worry about furnishing, walls, or family members when he is tossing it around. It is much more durable than most, with the exception of really heavy chewers/teething, even then it held up for a long time. As long as you are careful to remove it if they manage to chew through I would even try it out with teething puppies. The lawnmower is also this balls nemesis, it loses every time. If only I could convince the dog that he needs to stop sacrificing toys to the lawnmower :-)
