Unlock Maximum Torque and Precision with Starlock Technology

The Bosch OSL400F 4-Inch Starlock® Oscillating Multi-Tool Bi-Metal Segmented Saw Blade represents a new dimension in power transmission and utility. Featuring the revolutionary Starlock three-dimensional interface, this accessory provides a completely integrated system between your tool and the blade. Unlike flat interfaces, the 3D shape ensures the highest torque transfer, significantly reduced vibration, and superior performance in demanding applications. While designed for the next generation of high-performance Starlock tools, this blade remains backward compatible with standard OIS systems, ensuring it fits the oscillating tool you already own.

Swiss-made for professional precision, the OSL400F is engineered with a high-quality Bi-Metal cutting edge that excels in resisting wear when cutting hard materials. The 4-inch segmented design is ideal for making long, straight cuts in hardwood, wood with nails, and PVC, as well as flush cuts against surfaces like door jambs or baseboards. The color-coded interface and laser-etched markings make it easy to identify the right blade for the job instantly, keeping your workflow efficient and your cuts clean.

Key Features

  • Starlock Interface: 3D tool-accessory connection delivers maximum torque transfer and reduced vibration.
  • Bi-Metal Durability: Premium construction offers extended life when cutting hardwood, wood with nails, and non-ferrous metals.
  • Segmented Design: Flat side allows for flush cutting against existing surfaces; round edge enables precise rotation cuts.
  • Universal Compatibility: Fits Starlock tools and is backward compatible with OIS oscillating tools.
  • Precision Engineering: Swiss-made quality ensures accurate, clean cuts and professional reliability.
  • Easy Identification: Color-coded interface helps users quickly select the correct blade for the material.

They worked out great!!!
Color: D) 4-Pack 3" Balls (Yellow), Color: D) 4-Pack 3" Balls (Yellow)
So far have been the solution we were looking for! I was extremely tired of the non stop destruction and order of large Chuckit balls for our high energy/high drive dog. For about the same price I bought four 3 inch balls to test out their durability and fit for the thrower. THEY WORK! Perfection! They even make a fun whistling sound as they sail through the air. They do require a tad more muscle in the thrower but that is not a problem. They have already shown to be WAY more durable. The 3 inch balls work in the large chunkit thrower. Super find.

Durable

My dogs love them. They are very bouncy, and ideal size, and durable. Great alternative to a tennis ball which in my house only last 30 minutes.

Toughest dang balls I ever played with
Color: D) 4-Pack 3" Balls (Yellow), Color: D) 4-Pack 3" Balls (Yellow)
These things are amazing. We have a ball obsessed Husky mix and he has destroyed Kongs, Chuck Its, and a whole lot of other ball shaped objects. These things? We bought the 4 pack because we bought 4 Chuck Its and they lasted a year, all 4 of them only a year, before they were destroyed. A year after buying these? We only bought more because he lost 3 of them. I think we did find one under the dresser after buying this pack... But the others? They either ended up thrown over the fence into the woods or lost in the holes in the yard the monster digs up. Other than a few pockmarks from his teeth and maybe some mud, they may as well be brand new even after a year or two. Probably the most chew resistant thing we've ever bought him. They're really solid rubber and since he hasn't managed to bite into them to take out a chunk, they're safe as hell. Being as big as they are, I don't worry he's gonna choke unattended on them like the usual size of ball. About the only concern is forcing breaks so he can have breathing moments when he manages to talk us into fetch outside. It fits in the larger Chuck It thrower too, so we haven't lost any value from having those torn up.

Sturdy bouncy fun!
Color: D) 4-Pack 3" Balls (Yellow), Color: D) 4-Pack 3" Balls (Yellow)
Great product. My big 70lb Sheppard puppy loves it, hasn’t stopped playing with it since it arrived. She throws it about and chases it, had a good chew on it and even put it in her favorite toys bin. Sturdy, firm and very bouncy. And there are 3 more in the bag for an awesome price. Bright color will make it easy to find and holes thru it will prevent choking and I can string it on a line for training play.

Dogs love these
Color: C) 2-Pack 2.5" Balls (Yellow)
Great quality balls for tough chewers. I love them, but wish the orange ones were available more...I've been checking cuz they are easier to find in the yard than the green that blends in. Our dogs love them and I like the weight for throwing.
