From the Manufacturer The 6310-20 Milwaukee 18-volt cordless circular saw operates on a 2.4 amp hour nickel-cadmium battery providing the most 2 x 4 cuts per battery charge in the industry. On a single charge, the Milwaukee cordless circular saw can cut up to 145 2 x 4's or 106-feet of 5/8-inch OSB material. Milwaukee uses only no memory effect batteries, always providing the user with full battery capacity. This 6-1/2-inch saw includes an electric brake which stops the blade in seconds. The cordless circular saw can bevel up to 50-degrees for cutting extreme angles. The saw features all-metal upper and lower guards and a rigid aluminum shoe for rigorous job site use. A soft grip handle results in a more comfortable gripping surface. Batteries are interchangeable with other Milwaukee 18-volt tools adding versatility.
User reviews
Great with V18 batteries, Not so great with NiCads
I would have rated this saw higher in the battery life rating had it come with the V18 batteries. With NiCads the run time is pretty poor, with the V18 it is just tolerable. I use this saw fairly often for odd jobs and punch list type work, it serves me well. It will cut a fair amount of 2X material and or a few sheets of ply.It will cut 2X material at 45°. It won't do it as quick as a corded saw, but it will do it just the same.
This saw fits my hand well and is well balanced for cutting both on the flat and overhead. It is fairly light, though not as light as the Makita LXT. This saw works best with a thin kerf blade, standard kerf seems to kill batteries even quicker.
