Product Description
Milwaukee 3 pc Replacement Reaming Blades for Tubing Cutters
Model Number: 48-22-4257
The Milwaukee 48-22-4257 is a 3-piece set of Replacement Reaming Blades for Milwaukee copper tubing cutters — the reaming blade inserts that remove the interior burr from cut tube ends after cutting. Every tubing cut with a wheel-type cutter creates a small interior burr at the tube's inner diameter where the cutting wheel shears through the tube wall — this burr must be removed before making any type of fitting connection. If the burr remains, it reduces the tube's inner diameter at the connection point, creates turbulence in fluid flow at the fitting, can break off and travel through the system as a contaminant after installation, and prevents proper fitting seating in press-fit and compression systems where dimensional accuracy at the tube end is critical for connection integrity. The reaming blade's sharp edge removes this burr with a few twisting passes inside the cut tube end, producing a clean inner diameter that allows proper fitting engagement.
Reaming blades dull from the abrasive copper contact of repeated reaming operations, eventually losing the cutting edge sharpness that allows them to cleanly shave the burr from the tube interior in a few strokes — a dull reaming blade requires more strokes, more force, and still produces an incompletely deburred tube end. Replacing the worn reaming blade with a fresh Milwaukee replacement restores the fast, clean one-step reaming action that professional plumbing and HVAC work demands at the production cutting and reaming pace of commercial installations. The 3-pack provides enough replacement blades to refresh the reaming capability of multiple tubing cutters simultaneously or to maintain a single cutter through an extended project scope.
Compatible with Milwaukee tubing cutters equipped with Milwaukee's standard reaming blade slot — verify compatibility with your specific Milwaukee tubing cutter model before ordering.
