Milwaukee 6390-21 Circular Saw: Pricing and value
The Milwaukee 6390-21 Circular Saw is more expensive than most of the other circular saws we reviewed, but for good reason. It’s been designed for ease-of-use and power, and the price seems fair for a tool that makes your life easier. It’s probably most comparable to the Makita 5007MG Circular Saw, which tends to retail at $20-$30 more and is a bit more refined, but there isn’t much between them.
As you would expect at this price, the Milwaukee DWE575 Circular Saw packs more punch in both the power and features department than the Black & Decker BDECS300C Circular Saw (opens in new tab) or SKIL 5280-01 (opens in new tab), offering great value for enthusiasts and professionals alike.
Milwaukee 6390-21 Circular Saw: Features
One of the ways Milwaukee has made this circular saw so easy-to-use is through its ‘TILT-LOK’ handle. This cushion topped handle has eight different position options, so it can be adjusted to any cutting application while maintaining both comfort and control. Along with its superior visibility and a clear sight line from either side, Milwaukee has created a circular saw that’s a real pleasure to use.
It’s lightweight too and while at 10.4 pounds it’s not as light as the Black & Decker BDECS300C (opens in new tab), its 3.25 maximum HP means it packs a punch with one of the best power to weight ratios in the circular saw market - so it can handle tough materials, including headers, microlams and wet lumber, with ease.
It also comes with features that are well-considered for a professional workplace, such as a 9ft power cord and a lock-on switch for comfort during extended use. It’s also good at dust removal, but not as good as the Dewalt DWE575 Circular Saw (opens in new tab), so expect to spend some time dusting it off after use.
It is missing a few features you would expect from a higher-end model, like a laser guide for assisting in cutting straight lines and an electric brake to stop or slow the blade as soon as the trigger is released. But most noticeably, the Milwaukee 6390-21Circular Saw is missing bevel stops that would help you quickly adjust the tool to make bevel cuts at common angles, which you will find in the Makita 5007MG Circular Saw (opens in new tab).
However, a big plus point is the five-year manufacturer warranty, easily the longest of any circular saw we’ve reviewed.
Milwaukee 6390-21 Circular Saw: User reviews
The Milwaukee 6390-21 Circular Saw is a popular choice with users, scoring an average of 4.8 out of five on Home Depot. They particularly commended the saw’s power and ease-of-use, commenting that the price seemed more than reasonable for the performance and features on offer.
Lots of reviews noted how reliable the saw is, with a number particularly impressed with how well it kept up with high-demand and tough jobs.
Users were also pleased with the solid and strong carry case, while one or two noted that purchasing the rip guide add-on made for another nice extra that made this saw even more useful.
Negative points were few and far between, but one reviewer did find the cutout hole on the plate to be far too large, which made creating small notches at the end of pieces of wood difficult.
Should you buy the Milwaukee 6390-21 Circular Saw?
As you approach the more professional end of the market you’ll find both better features and a higher price, while the Milwaukee 6390-21 Circular Saw isn’t quite at the very top-end, it still offers a great range of professional features at a reasonable price. The ease of use and ergonomic design are great for anyone expecting to use this saw for long periods of time and will definitely be worth the extra cash.
It’s a great choice for professionals or hardcore DIYers, but if you’re just dipping your toe in the circular saw world, we’d recommend trying out a cheaper model to start with, say the Black & Decker BDECS300C (opens in new tab), which is less than half the price of the Milwaukee 6390-21.
