Overview
The M1R is a compact 4 inch cutting tool from Crescent, built with molybdenum jaws and a metal handle, weighing 0.83 pounds in total. Its small size sets it apart from the larger cutters in Crescent's lineup.
At only 4 inches long this reads as a mini diagonal cutter meant for tight spaces rather than heavy gauge wire, and the metal, not dipped, handle means there is no built in insulation, so it should not be used near live electrical work.
- 4 inch length
- Molybdenum material
- Metal handle
- 0.83 pound weight
Who it's for
Fits electronics, jewelry or craft work where a small cutter reaches into confined spots. Not the choice for anyone needing insulated handles for electrical work or cutting heavier gauge wire.
Pros and cons
- Compact 4 inch size for tight spaces
- Molybdenum jaws for edge retention
- Bare metal handle, no insulation for electrical work
- Small size limits leverage on thicker wire
Performance notes
Molybdenum jaws hold an edge well for repeated light cutting, and the 4 inch size favors precision over leverage, so it will handle fine wire more comfortably than thick gauge material.
