Execute Surgical Remodeling Plunge Cuts and Pierce Cleanly Through Construction Nails Natively
The DEWALT DWA428SET 8-Piece General Purpose Oscillating Multi-Tool Blade Set is an industrial-grade cutting accessory kit engineered to perform flush and plunge cuts in demolition and renovation environments. This high-performance collection features bi-metal blades utilizing specialized PlungePoint™ tip geometries that deliver up to 7X longer service life when slicing through dense, nail-embedded structural framing lumber. Outfitted with a universal fitment interface that mounts tool-free onto major oscillating multi-tool platforms without adapters, this heavy-duty set handles repetitive pass lines through wood, metal, PVC conduit, and gypsum drywall panels.
Best Used For:
- Remodeling Floor Prep: Slicing flush through thick wood door jambs and casing profiles directly over old finish floor surfaces without marring sub-surfaces.
- Embedded Fastener Demolition: Cutting cleanly through hidden framing nails, steel trim staples, and structural hardware buried deep inside residential partition wall studs.
- Utility Box Installation: Executing clean, dust-controlled rectangular plunge cuts into building drywall partitions or rigid PVC wiring conduits for outlet housings.
Key Performance & Safety Features
- 7X Wear Lifetime Multiplication: Premium bi-metal tooth matrices coupled with an advanced surface armor shield outwear standard high-carbon alternatives inside embedded wood.
- PlungePoint™ Piercing Edge: Unique tip geometry establishes a stable starting bite to run quick, vertical plunge adjustments without skipping across hard faces.
- Universal Tool-Free Adapter Interface: Open anchor slot layout mounts directly onto most commercial brand multi-tools for instant quick-change operations.
- Induction Tempered High-Speed Steel: Hardened tooth faces withstand high-velocity metallic strikes against framing fasteners without premature fracturing or flat-spotting.
- Titanium Protective Film Coating: Outer chemical vapor deposition shield minimizes processing friction heat to expand structural blade endurance.

PRO-TIP: When dropping these bi-metal blades into structural wood studs containing embedded nails, alternate your multi-tool stance slightly with a gentle rock-and-sweep motion. This uniform oscillation avoids local stress overheating on single tooth segments, using the full width of the high-speed steel edge to sever hardware clean and flat without stalling.

I use it for myself not my pet
I sewed a fluffy velcro pouch to put this in, and then I wrapped the pouch around a microwavable heat gel pack in order to get the sensation of both heat and heartbeat while hugging a large stuffed animal. It works great. It's not too loud if you position it right. It helps me to fall asleep and not feel lonely or touch starved. The battery lasts a long time and I don't have to recharge it very often. I only wish that the speed of the heartbeat was adjustable so that I could slow it down a little more so that my own heartbeat might try to match it.

Easily Exposed Lithium Ion Battery
I am returning this item for my money back. Apparently, they think they can charge $16 for a piece of plastic and not even put a screw on the back to hold the panel closed. My dog is smart and a little rough when anxious. I wanted a rechargeable heart (to avoid buying batteries) to help with this anxiety but cannot risk the Velcro coming undone and him biting the heart by mistake. The panel slides off very easily. There's a reason that lithium ion batteries aren't usually easily accessible. I'm not risking my dog discovering a battery and wire in the heart. Even with appropriate supervision, accidents happen. I don't even understand why I would need to access the battery when it's rechargeable. I don't recommend purchasing this product for that reason alone.

bottle baby kittens preferred this heartbeat to having warm snuggle safe heat disk
Ok... when I got this I thought.. "are you kidding me?" they are going to like this.
Joke was on me. They love it. It is rhythmic and it is strong enough that it pulsates the area so all of them can feel it. They consistently would lay on top of the heart rather than in the area of their "crib" where the heat was.. and this was when they were still only a few days old! It works.
So this is what you want to know.
It beats continuously for about 4-5 days without needing a recharge.
Recharge is fast and only takes a couple hours
The button is slightly "inside" the unit so when it is placed upside down there is no way that it can accidentally be turned off. Which is great. If the button were on the upside in the pet space then a foot or body part of the little animal could turn it off inadvertantly. Design to put the button slightly inset is extremely important design feature - makes this excellent. When I turn it on I know it will be going as long as the battery still has charge. .
I don't think it is waterproof so I put it under the pee pad that I had under the blanket bedding and it was still easily heard AND felt. If not using a pee pad I would definitely put it in a small ziplock bag to protect from any leaked urine or liquids to keep it safe.
When the kittens were done eating they would gravitate towards the heart beat... (with their eyes open or when they were still closed after birth it was the same response). This little gadget was a total lifesaver as it really calmed the kittens in ways I would not be able to.
These pictures are of the trio that LOVED this.... Meet Zen (tabby M with white feet), Sugar (tuxedo F with white feet) and Rocket (ginger - M). All cisgender. they were about 3 days old when I got them to foster.. photos from arrival until about 3 weeks of age. Photo with q-tip is to give relative size on arrival. They will be up for adoption in Tustin CA in another 2-3 weeks time.

Fantastic!
The heart that came with Snuggle Puppy was a pain to replace the battery. This is the only rechargeable heart I could find searching online. I was a little concerned reading it’s a “frequently returned item.” But happy to say, we will not be returning this! It shipped charged and the heart is still beating non-stop days later! It’s sturdy and fits in the snuggle puppy perfectly. We have a tiny 17 yr old Chihuahua who never chewed anything up so it’s completely safe for her to enjoy. It helps with her anxiety. You can hear the beat in the video—it’s nice and loud and has a bit of a vibration. Our pup has been sleeping next to it every night. Very happy with this purchase. From reading reviews, I trust if we have an issue with it, their customer service will help. For now, it works! I really like that it has time options—can set it for 2 hrs of heart beating or non-stop.
