Milwaukee M18BSX Heavy Duty Sawzall Reciprocating Saw 2 x 4.0Ah

Faster cuts, longer run times - with the Milwaukee M18 FUEL™ Sawzall, you'll maximise your productivity on site when cutting through all kinds of materials. This cordless reciprocating saw delivers a 28.6mm stroke length and a speed of 3000 strokes per minute for extremely fast cutting.
A high-performance 4-pole motor maximises the power to weight ratio, while a counter balance mechanism reduces vibrations for more control and faster starts when cutting metal. Keyless blade changes are quick and easy thanks to Milwaukee's FIXTEC™ clamp design, and the comfortable grip puts you in complete control.
This Milwaukee M18BSX reciprocating saw is powered by the brand's high-performance POWERSTATE™ brushless motor, and uses REDLINK PLUS™ intelligence hardware and software - this combines to deliver outstanding power, run time and durability on the jobsite. It's compatible with all M18™ batteries, and you'll get two 4.0Ah packs included, along with a charger and kit box to carry it in.
