DeWalt DCS727 54V XR Flexvolt Cordless Brushless Mitre Saw 250mm

The DeWalt DCS727 54V XR Flexvolt Cordless Brushless Mitre Saw 250mm is a heavy duty sliding compound saw. It aims to match a corded machine while running on 54V Flexvolt batteries. That frees you from mains power on remote jobs. It is sold body only or as a kit with a 6.0Ah battery and charger.

Rails do the heavy lifting. Linear 32mm horizontal rails with roller bearings give precise travel. They carry cuts up to 305mm wide. The base and fence are machined to tight limits for 0.1 degree accuracy in key applications. A large dual sliding fence supports big material. Capacity at 45 degrees is 210 x 77mm.

The mitre moves 50 degrees left and 60 degrees right, and a cam action lock makes setting angles quick. A grooving stop controls depth for rebates and grooves. The brushless motor spins the 250mm blade at 4,300 rpm and saves battery energy. Integrated carry handles help you move the 20.5kg saw.

Flexvolt batteries are the clever bit. A 54V tool needs a 54V battery. The same battery steps down to 18V mode and fits your 18V XR tools. So the saw suits trade fitters who already run DeWalt 18V gear. The box has a material clamp but no battery and no charger.

Flexvolt batteries switch voltage by themselves. In a 54V tool such as this one they run at 54V with lower amp hours, and in an 18V tool they run at 18V with higher amp hours. The brushless motor wastes less energy as heat so each charge goes further. Roller bearings on 32mm linear rails cut play in the slide, which keeps the 305mm cut square from start to finish.

Remove the battery when you change blades or clean the saw. Clamp the work with the supplied material clamp and keep hands clear of the blade. Set the mitre lock and grooving stop before you start. Check the fence is fully supporting long pieces. Wear eye and ear protection because sound power reaches 112 dB(A).
