The Milwaukee 48-00-7252 9-Inch 5 TPI AX with NITRUS Carbide Teeth SAWZALL Blade for Wood with Nails is a reciprocating saw blade built for demolition and remodel work where the wood is full of fasteners. This is a carbide-tooth reciprocating saw blade designed for cutting nail-embedded wood, screws, and roofing materials. Model Number: 48-00-7252. The pack contains one blade.

The AX line has long been the go-to demo blade for wood with nails. This version steps the teeth up to NITRUS carbide, and Milwaukee rates it for up to 2X life versus standard carbide teeth in wood with nails. In practical terms, that means more cuts through old framing, subfloor and sheathing before the blade gives out, and fewer trips back to the truck for a fresh one.

Three design details do the heavy lifting. The NAIL GUARD design is meant to rip through nails rather than lose teeth on them. The FANG TIP is shaped for fast plunge cuts, so you can start a cut in the middle of a wall or a deck board without a pilot hole. The optimized tooth geometry adds durability when you hit hardened fasteners like deck screws and drywall screws, which chew up standard blades quickly.

The aggressive 5 TPI tooth pattern is tuned for speed in wood. Big gullets clear chips fast, so the saw keeps cutting under load instead of clogging. Milwaukee lists applications that include wood with screws, wood with nails, shingles and roofing material, hardened fasteners, cement board and plaster.

The 9-inch length is the middle of the AX NITRUS lineup, which Milwaukee also offers in 6-inch and 12-inch lengths and in 1, 3 and 5 packs. Nine inches gives enough reach for doubled top plates, stacked studs and most joist cuts while staying controllable in tighter bays. The blade fits all reciprocating saws, so it works in a SAWZALL or any other brand of recip saw.

Who should buy it: remodelers, demolition crews, roofers, restoration contractors and serious DIYers gutting a room. If your cuts routinely hit nails, screws or roofing material, this blade is built for that work. If you only cut clean lumber, a standard wood blade will cost less.
