Milwaukee M12 FCS442-0 12V FUEL Brushless 140mm Circular Saw - Body
Discover cutting-edge performance in a truly compact form with the Milwaukee M12 FCS442 12V FUEL Brushless 140mm Circular Saw from ITS.
Designed to redefine what’s possible in tight workspaces, this cordless saw brings pro-level power, precision and mobility to your job site.
The lightweight magnesium shoe enhances durability while keeping the tool nimble, so you can manoeuvre easily across framing, sheathing or finish-work without fatigue.
Whether you’re cutting sheet goods, framing timber, making rip cuts or dropâsawing in tight spots, the M12 FCS442 puts you in control. Its integrated dust blower clears your line so you stay accurate and visible, and the built-in LED further improves visibility in dim, enclosed areas.
From the moment you pick it up you’ll notice how the precision-machined magnesium shoe keeps the tool lightweight while maintaining rugged durability for heavy-duty job-site abuse. The integrated dust blower keeps your cut-line clear of debris so you can see exactly where you’re cutting, and the built-in LED adds visibility in darker corners or awkward angles.
When it comes to capacity this sub-compact circular saw punches above its size. With a 140 mm blade and 20 mm bore it’s capable of a maximum cutting depth of up to 46 mm at 90°, and around 32 mm at 45° bevel, so you’re not limited to shallow cuts - you can confidently tackle standard timber, sheet goods and framing tasks.
In practical terms this means the M12 FCS442 isn’t just about being small - it’s about being strong, efficient and reliable in real-world trade conditions.
For installers, carpenters, renovators or contractors working in tight shafts, stairwells or overhead situations, this saw offers the kind of portability and freedom that makes job-site access less of a headache - and the work faster, cleaner and more professional.
The M12 Sub Compact Circular Saw includes three of Milwaukee’s exclusive technologies all for your benefit. The POWERSTATE Brushless motor helps maintaining the tool and ensures a longer operational life; the REDLITHIUM Battery packs which provide exceptional power for longer; and the REDLINK PLUS overload protection – maximising the power you need when you need it.
At the heart of the machine is the brushless motor that allows you to use the tool efficiently. As part of the design, the tool utilizes every bit of battery power when you need, all while reducing the need for ongoing maintenance by reducing the amount of heat generated and working more efficiently.
The technology in creating a brushless motor system allows for perfect symmetry between battery power and usage ensuring you get all the power you need, when you need it.
