Milwaukee MIL48-00-4093 Reciprocating Saw Blade 8 Inch High Speed Steel 3/4 Inch

The Milwaukee MIL48-00-4093 is a reciprocating saw blade, high speed steel, 8 inch long, 3/4 inch wide, 80 teeth, 8/12 TPI, for metal, 0.05 inch thick, 5 pack.

The 8/12 TPI designation is the specification and it describes a variable pitch blade — the tooth spacing changes along the blade rather than staying constant. That is a genuine piece of engineering and it solves a real problem.

A constant-pitch blade has a natural frequency. Cutting metal, the teeth engage at a regular interval and the blade sings — it resonates, which is where the noise, the vibration, and much of the tooth breakage come from. Varying the pitch breaks up that regularity. The blade cannot settle into a resonance because no two engagements are the same interval apart.

The practical results are less vibration, less noise, and longer blade life.

The variable pitch also widens the material range: the fine end handles thin material where three teeth must stay in the cut, the coarse end clears chips in thicker stock.

High speed steel is the blade material — hard, holds an edge in metal, and more brittle than bi-metal. HSS blades cut well and snap when flexed, which is why bi-metal dominates recip saws where the blade gets bent.

The 5 pack acknowledges these are consumables.

Applications include metal cutting, tubing, and maintenance.
