What is the arbor size for this saw?
The Milwaukee 6470-21 has an arbor size of 5/8".

The 6470-21, 10-1/4" circular saw is built with the power and capacity to handle the most extreme cutting applications. The powerful 15 amp, 5,200 rpm motor delivers maximum power for high performance cutting without bogging down under load.

These heavy duty features combined with the 3-13/16" depth of cut capacity and 60° bevel capacity make the 6470-21 the most popular 10-1/4" circular saw in the industry.

Like many retailers, Build.com can choose to set its own prices independently. And even though manufacturers require Build.com and other retailers to display a product's "minimum advertised price" (or MAP), the retailer can choose to sell for less than that. But the price must be conveyed in other ways, and each individual manufacturer's MAP policy determines where the price can be seen.
To see the price for this product at Build.com, you'll need to place it in your shopping cart, and maybe even proceed to final checkout. If you're not ready to buy the product, simply remove it from the cart.
Build.com apologizes for any inconvenience. We'd just like to offer you the chance to save extra money while we adhere to manufacturers' MAP policies. Build.com is also working to educate manufacturers on how their policies impact customers and their buying behavior.
