Milwaukee 7-1/4" Tilt-Lok™ Circular Saw 6390-21
Model Number: MIL639021
ENGINEERED ERGONOMICS MEETS UNRIVALED POWER-TO-WEIGHT PERFORMANCE
When the job demands high-volume ripping and repeated framing cuts, the mechanical efficiency of your circular saw determines the pace of the project. The Milwaukee 6390-21 is built around a high-output 15-amp motor delivering 3.25 maximum horsepower, providing the torque necessary to power through dense LVL, wet pressure-treated lumber, and thick headers without bogging down. What sets this unit apart is the revolutionary Tilt-Lok™ handle system, which allows for eight distinct positions to match the specific ergonomics of your cut—whether you are working at waist height on a sawhorse or reaching overhead. By optimizing the handle angle, you reduce wrist strain and improve tracking accuracy, ensuring that the 5,800 RPM blade stays perfectly on your line. The inclusion of helical steel gears ensures maximum power transfer and long-term durability, while the 50-degree bevel capacity provides the versatility needed for complex compound miters and roof rafter cuts.
- / 8-Position Tilt-Lok™ handle provides customizable ergonomics for maximum comfort and control in any cutting application.
- / 15 Amp, 3.25 Peak HP motor delivers the industry's best power-to-weight ratio for demanding professional use.
- / 50-degree bevel capacity with superior visibility provides a clear sightline to the blade from either side of the tool.
- / Heavy-duty helical steel gears and a 22-amp switch are engineered for extreme jobsite durability and long-term ROI.
- / Lightweight 10.4 lb. design reduces operator fatigue during extended use without sacrificing cutting depth or torque.
