EXPERIENCE SUPERIOR LIFE AND SPEED WITH M42 COBALT ALLOY

Elevate your drilling performance with the Bosch HBT338 3-3/8 Inch Bi-Metal Hole Saw, engineered for professionals who demand durability and versatility. Crafted from an enhanced M42 alloy containing 8% cobalt, this hole saw is built to withstand high-temperature applications, delivering up to 20% longer life than standard bi-metal saws. Whether you are cutting through tough metal, wood, drywall, or plastic, the reinforced shoulder design provides added strength to handle deep cuts with precision and stability.

Efficiency is at the core of the HBT338 design. It features a unique "Triangle Slot" architecture that significantly improves plug removal and reduces heat buildup during operation. Combined with Bosch's innovative Progressor tooth design—which utilizes alternating tooth sizes—this accessory cuts faster and stays sharper longer across multiple materials. With a generous 1-3/4 inch cutting depth, this tool is the ideal solution for clean, deep boring in complex construction and renovation projects.

Key Features

  • Enhanced M42 Alloy: Contains 8% cobalt to resist high heat and deliver 20% longer service life.
  • Progressor Tooth Design: Alternating tooth sizes ensure faster cutting and superior performance in wood, metal, and plastic.
  • Triangle Slot Design: Specialized "shark tooth" side slots allow for rapid, easy plug removal and better heat dissipation.
  • Deep Cut Capacity: Features a 1-3/4 inch cutting depth to handle thicker materials and multi-layer applications.
  • Reinforced Shoulders: Structural reinforcement adds strength to the saw cup for heavy-duty use.
  • Multi-Material Versatility: Optimized for clean cuts in drywall, metal, plastic, and wood.

Great buy
Size: 2 Count (Pack of 1), Style: Pack of 2
Easy to track balls. My dog loves them and I like that they whistle when you throw them cause some times my dog loses track of it in the air. This helps because they can hear where it's going. Will buy again.

My Dog's Favorite Balls
Size: 2 Count (Pack of 1), Style: Pack of 2
My dogs love these balls and won't play with any others. My lab has to carry the orange ball and track and retrieve the blue one. We have a system!

Our perfect chew toy for a relentless chewer!
Size: 2 Count (Pack of 1), Style: Pack of 2
We have looked high and low for a ball that our Australian Shepherd couldn't destroy. Read on to find out why we are sticking with this one. We've used other Chuckit! products in the past to mixed degrees of success. We absolutely love the ring fetch toy, though the dog can destroy those rings in a couple days. We tried other "nearly indestructible" balls only to have to throw them away within a couple days because our dog had destroyed them and left small pieces around the house for the baby to find. We have been COMPLETELY satisfied by these balls. They fit with the Chuckit! stick, which is a great bonus, but the most important thing is the dog hasn't been able to get pieces torn out of them. His orange one is his "indoor toy" and he's been going to town on it for weeks without any indication of wear. We periodically inspect it and are always floored to see that it's generally in the same condition as when we gave it to him. The orange color did fade a little when he left it outside for a few days in the sun, but considering how well it works otherwise, this didn't concern us at all. The "whistling" aspect of this ball is... well, an interesting gimmick but I wouldn't buy it if that's what you're interested in. Sometimes it makes noise in flight, other times it doesn't. We don't care. He chews it until he's tired of it (which is usually hours) and it squeaks and squorks on his teeth which keeps him happy as a clam. We honestly didn't think we'd find a ball that could keep up with his chewing, but this one has been phenomenal. We cannot recommend it enough!

Our German Sheppard loves these
Size: Medium
These cost a bit more than tennis balls, but they are so much nicer and longer lasting. For starters, they stay cleaner than tennis balls because they’re smooth rubber. Dirt won’t build up on them and if anything does stick, like grass or soil, it falls off once the dog slobber dries. They’re also thick, so they don’t fall apart or blow out like a normal tennis ball does in our dog’s jaws after 30 seconds. Our GS chomps on these like crazy and the only damage they’ve suffered is a crack that developed from the edge of the hole, but the crack is growing very slowly and none of these balls have totally failed yet. The balls do whistle when thrown ant high speed and that may help a dog track and locate it, but I’m not sure. Our neighbors hear the whistling too so it’s far from silent. Lastly the orange ball is easy to locate out in our yard, but the dark blue practically disappears.

Great for smaller dogs
Size: Small
These two balls are perfect for the smaller mouthed dog that loves to play fetch. These balls are not only super durable (lots of teeth biting), but float in the baby pool we use for our miniature dachshunds. The value here is much better than you’d find anywhere else. The noise, if bitten hard enough, was “low” at best. Easy to spot/find if overthrown. Will definitely buy again once these are in bad repair; so far, so good-love these for my fur babies!
