Milwaukee SAWZALL Blade for Medium Metal (14 TPI, 5-Pack)

14 TPI is Milwaukee's medium metal tooth pitch, aimed at thicker-wall stock than a fine-tooth blade: think unistrut, angle iron, pipe and heavier conduit. The blade body runs 0.035 in thick. For thin sheet metal or EMT you want a higher tooth count, and for thick plate a coarser pitch cuts faster.

Both lengths are offered: the 6 inch is 48-00-5182 and the 9 inch is 48-00-5187. Use the 6 inch for general cutting in tight spots and overhead work, where less blade means less flex and less whip. Go to the 9 inch when you need reach through a wall, past a flange, or to cut larger diameter pipe in one stroke.

Yes. SAWZALL blades use the standard universal reciprocating saw tang, so they drop into any brand's recip saw with a standard blade clamp, DeWalt, Bosch, Makita or Ridgid included. The tang on these is reinforced with Milwaukee's Tough Neck ribbing to cut down on breakage at the clamp, which is where most blades fail.

Bi-metal. They use Matrix II bi-metal teeth, which flex rather than shatter and hold an edge longer than a plain carbon steel blade. Milwaukee rates the tooth geometry at twice the life of their previous generation SAWZALL blades. If you are cutting cast iron, stainless or abrasive material regularly, a carbide-tooth blade is the better buy; for everyday steel MRO work, bi-metal is the normal choice.

Five blades per pack. That is the standard count for both the 6 inch (48-00-5182) and 9 inch (48-00-5187) 14 TPI metal blades, which makes them practical to stock on a service truck or in an MRO crib rather than buying singles.

Buckling is the common complaint with metal-cutting recip blades, and these address it two ways: a Grid Iron honeycomb pattern stamped into the body increases rigidity, and the 0.035 in body thickness gives it backbone without making the kerf excessive. The shorter 6 inch version flexes less than the 9 inch, so for overhead and awkward angles the 6 inch is the safer pick.

Country of origin on these 14 TPI metal SAWZALL blades is the United States, which matters for agencies and institutions working under domestic sourcing preferences on their purchase orders.
