MAXIMIZE SHEET METAL CUTTING SPEED WITH IMPACT RATED DURABILITY

Experience superior dependability and value with the Bosch EDGE™ 1-1/2 In. Impact Tough™ Bi-Metal Hole Saw. Engineered to withstand the high torque of modern impact drivers, this accessory delivers up to 2X the life of standard impact-rated hole saws. The robust 8-TPI bi-metal teeth are specifically designed for clean, rapid cuts in sheet metal, making it an essential tool for HVAC technicians, electricians, and metal fabricators who demand efficiency and precision.

Designed for convenience and performance, the HTW112 features an integrated one-piece design that eliminates the need for a separate arbor or pilot bit. It is equipped with a built-in depth stop to prevent breakthrough, ensuring accurate hole depth and protecting the work surface. Additionally, the pilot bit spring facilitates automatic plug ejection, speeding up repetitive drilling tasks. With a 1/4-inch hex shank, this hole saw offers universal compatibility with impact drivers and standard drills, providing extreme performance on any job site.

Key Features

  • Extended Life: Durable design delivers 2X life versus standard impact-rated hole saws.
  • Sheet Metal Optimized: 8-TPI Bi-Metal teeth are engineered for fast, clean cutting in thin gauge metal.
  • Impact Rated: Built to handle the high torque transfer of impact drivers for extreme performance.
  • Integrated Design: One-piece construction means no separate arbor or pilot bit is required.
  • Precision Control: Built-in shoulder serves as a depth stop to prevent breakthrough.
  • Automatic Ejection: Pilot bit spring automatically ejects the material plug for faster workflow.
  • Universal Fit: 1/4-inch hex shank fits all standard impact drivers and drill chucks.

Glow and play - pups favorite!
Color: A) 2-Pack (2.5" Balls)
I can't say enough good things about this glowing fetch ball! It's perfect for outdoor play at night—my dog loves chasing it in the dark, and the bright glow keeps the fun going even after sunset. What really impresses me is the quality; this ball has withstood my pup's enthusiastic chewing (and believe me, he can demolish a regular ball in seconds). It’s durable and built to last, making it a fantastic investment for any dog owner. If you're looking for a fun nighttime activity, this glowing fetch ball is a must-have!

My Dogs Favorite for throwing
Color: D) 2-Pack Lattice (3.25" Balls), Color: D) 2-Pack Lattice (3.25" Balls)
We brought our new adoptee home end of July, and I quickly had to find him replacements for his tennis balls because those balls are inherently abrasive and our yard has sand which gets in the fuzz and makes them extra abrasive and they were already causing tooth wear (our previous shepherd chewed tennis balls like gum for a week after his adoption, wore his teeth tips enough I noticed and I took them from him too but this guy didn't like the hand me down replacement, it was too big for his preference so I had to hunt down different ones for the current dog). I tried the glow in the dark Chuk It ones, but he doesn't like to carry them, or the smaller regular chukits... My current dog prefers these web style ones. I like glow in the dark stuff and it makes them easier to find in the evening or over night (if you have night adjusted eyes and not a lot of lights in the yard these are VERY glowy at night). Now I know he likes them I am thinking winter is coming and I may lose the glow color in the Michigan snow, so I'm here to order some in some in non snow camouflage because I want to be able to play in the winter without as much groping for hiding balls (literally he will chase and then snub any other balls in the yard I throw except the huge jolly ball but that isn't a fetch type ball, its a thrash toy. these are the only ones he will actually return for me to swap and throw indefinitely). I included video and a picture of them at the local beach. They float with enough above the water for maybe a few ants to use them as a flotation device, but take a bit of time to come to the surface when they splash down. I think brighter colors will help make them easier to find in the water as well as the snow. I think my dog likes them because the webbing design makes it easier to grip, even when slobbery his teeth can get a hold in the gaps (so can fingers haha) without slipping too badly. They also compress almost flat and boing back into shape and seem to be durable over at least 6 weeks of summer living in the yard, so far so good. They don't have a huge amount of mass so they don't whip super far but if you get a technique down you can get very reasonable distance on throws. He doesn't gnaw on them, so I can't speak to resistance to actual shearing attempts with teeth, just grab and chomp for fun, then holding in his mouth. My dog weighs about 68 lbs (we are trying to gain a bit), he is a German Shepherd, and this size fits him well (can't remember which size I got but usually Amazon shows what size the reviewer got near the title of the review. They're big enough I'm not worried he will accidentally swallow or choke on them, small enough his mouth fits them comfortably, his grip is secure because of the gaps, and he loves them. I suggest get two at least unless your pooch is super good about dropping it and letting you pick it up. With two, I can whip a ball, find the one he just dropped, and by the time he is back, I have the other one in hand. He knows I won't throw it unless he drops the one he just returned (I will wait for him to remember this), and this makes it way easier to play thow and bring it almost back (he often drops it at speed when he is nearly back to me so it rolls past me) without playing chase me for the toy... and makes reinforcing Drop It as an safe thing to do, like he isn't going to lose out if he drops the fun ball in his mouth, I have the second ball to mark (say YES!!! when he drops it) and immediately reward by throwing the ball I already had... he loves them enough that he thinks other balls are stupid so I don't want to throw a less cool ball to exchange for the cool ones haha Anyway hope this was helpful, Im off to order some of these balls in brighter colors for lake and snow visibility.

Fun Glow Balls for Night Play, Great Value
Color: A) 2-Pack (2.5" Balls)
The Chew King 2 Piece Glowing Fetch Balls are a solid, budget-friendly alternative to Chuck-It glow balls. While my pups prefer the mouth feel of the Chuck-It balls, these still provide bright, visible fun for dusk or nighttime play, and can even be used indoors with a flashlight to get the game going. Durable, glowing, and engaging—a good option for evening fetch sessions which always insures that our pups get a great night of rest.

Durable, Perfect Size, and Glows
Color: A) 2-Pack (2.5" Balls)
I bought these for my 23 pound Bojack (Boston Terrier/Jack Russel) mix and he absolutely loves them. He’s an aggressive chewer that has destroyed Kong toys. This ball has just enough flex or give in it that he can’t tear it apart as it compresses in on itself. After about 6 months it started to wear down and tear a bit by the hole so I just tossed it and gave him the other one. I’ll be buying more of these as they wear out over time.

A Must for Nighttime Fetch!!
Color: A) 2-Pack (2.5" Balls)
These are an absolute Must!! We have an ESS who is nearly 2yo and destroys Every toy he has. For some reason, he doesn't try to annihilate these glow balls. If he chomps on them, it's just for a moment while he is bringing it back to you. Has just a little weight to them so it goes far enough when thrown and a nice bounce when we have to play in the house, due to weather. Wish the bright 'glow' held a little longer but stays dim for quite some time and overall, just Awesome! Also purchased the 'chuck it' brand and sent them back because these were so much better. Will be buying more, if ever needed, but haven't had to because they are So Durable.
