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.

Best grinders I have ever used
Color: Stainless Steel
I bought these 6 months ago and they are great. They have stopped charging several times. The problem is the salt gets on the contacts and oxidized the contacts and the unit stops charging. You take sand paper and clean the contacts and they work fine again. I feel if the material on the charging port is made with stainless steel and the contacts on the grinders themselves are larger, I would have given this a 5 star. Even
As it stands, I would purchase these again. I have several bad experiences buying manual grinders that last about a month and break. These are High Quality, but need to upgrade the contacts.

Salt n peppa
Color: Stainless Steel
Not sure why I waited so long to purchase these! They are great, nice sleek design and they make cooking so much easier! They work so well and I literally just hold it over whatever I’m cooking, press a button and fresh pepper and salt are grinding right before my eyes! In the past my shakers have left salt or pepper on the counter but so far these have not, which is a bonus for sure!

Convenient and sleek
Color: Stainless Steel
These are very easy to use with one-hand operation. The adjustable grind settings work well, and the light feature is actually helpful when cooking.
The stainless steel design looks modern on the counter. Grinding power is consistent and strong enough for everyday kitchen use.
Pros:
• Easy to operate
• Adjustable grind size
• Attractive design
Cons:
• Requires batteries
• Slightly taller than manual grinders
A convenient upgrade from manual mills.

Quiet, Powerful, and Reliable — The Best Grinder Set We’ve Owned
Material Type: Updated-Stainless Steel
After going through several cheaper grinder sets that never held a charge, struggled to grind properly, and eventually broke, I decided to invest in a higher-quality set. This one seemed to check all the boxes — sleek design, convenient charging stand, and an overall premium look — so we decided to give it a try.
From the moment we charged them up, filled them with our favorite salt and pepper, and started using them, the difference was night and day. The grind adjustment is impressively versatile, ranging from coarse to very fine, and it’s much easier to adjust than on our old grinders.
The charging base uses a USB-C connection, which is a big plus — it works with the same chargers we use for our phones. Aside from the initial charge, we’ve only had to recharge them once in more than six weeks of regular use. The grind quality is excellent, the operation is smooth and quiet, and they don’t sound like they’re straining like our previous sets did.
If you’ve been disappointed by cheap electric grinders in the past, do yourself a favor and upgrade to this set. It looks great, performs flawlessly, and is absolutely worth the investment.
