Milwaukee MIL48-39-0521 Portable Bandsaw Blade 18 5/32" to 3/16" thick

The Milwaukee MIL48-39-0521 is a bi-metal super tough portable bandsaw blade, 18 TPI, for cutting stock 5/32 inch to 3/16 inch thick, for band saws using 44-7/8 inch x 1/2 inch x .020 inch blades, 3 per pack.

The stated cutting stock range of 5/32 to 3/16 inch is unusually specific for a blade listing and it is the most useful thing here, because it is the rule made explicit.

Bandsaw and recip blade selection follows one principle: at least three teeth must be in contact with the material at all times. Below three, the workpiece drops between teeth, the blade grabs and hooks, and teeth strip off the band. Stripping teeth on a portable bandsaw ruins the blade instantly and can throw the band.

Eighteen teeth per inch keeps three engaged in stock of roughly this thickness. Thinner material needs the 24 TPI blade in the same range; thicker material wants a coarser pitch that clears chips instead of packing.

The 44-7/8 x 1/2 x .020 dimension is the fitment specification and it is absolute — bandsaw blades are made to a machine's wheel spacing, and a blade of the wrong length simply will not fit.

Bi-metal welds a high speed steel tooth edge to a spring steel body: hard teeth on a band that flexes around wheels without cracking. That flexing is why bi-metal is essential in a bandsaw.

Applications include conduit, pipe, angle, and structural cutting.
