Pros & cons
Metabo HPT MultiVolt C3607DB "The Stud" Circular Saw
- ✓Outright fastest in Pro Tool Reviews' 2026 head-to-head — an 84-in rip through double-stacked 3/4-in OSB averaged 10.57 seconds, quickest of twelve saws tested, beating Milwaukee's M18 Fuel by over a second in full-depth rips.
- ✓Torque Boost mode delivers roughly 40% more torque than the prior generation for wet PT lumber, LVL, and other dense stock — press the button and it trades RPM for grunt instead of stalling.
- ✓Hybrid power is unique in the class: any MultiVolt battery, or the ET36A AC adapter for unlimited corded runtime on production days.
- ✓Massive runtime — rated up to 770 crosscuts in 2x4 SPF per charge on the big MultiVolt pack.
- ✓Kit value undercuts every 36V-class rival: about $379 with battery and rapid charger versus $499 for Milwaukee, $439 for Flex, and $609 for Makita's XGT kit.
- ✓Electric brake, LED light, folding rafter hook, and a visible cutting-depth indicator are all standard.
- ✓55° bevel capacity and clear sightlines to the cut line drew specific praise from reviewers.
- ✓Lifetime tool warranty — the longest coverage of any major saw brand.
- ✗No dust collection port, and no adapter available — Pro Tool Reviews called this out as its one real miss for indoor or track-adjacent work.
- ✗2-7/16 in cut depth at 90° trails deep-cut rivals like Makita's XSH06 (2-5/8 in).
- ✗Torque Boost's 4,300 RPM means slightly slower (if unstoppable) cutting while engaged — it's a trade, not free power.
- ✗At 10.5 lbs with a MultiVolt pack it's heavier than 18V/20V-class saws like Milwaukee's 2834 (~9 lbs loaded).
- ✗The ET36A AC adapter that enables corded operation is a separate ~$100 purchase.
- ✗Stamped aluminum shoe rather than the magnesium base some competitors use at this price.
- ✗MultiVolt is a smaller ecosystem than DeWalt, Milwaukee, or Makita — fewer tools and third-party batteries if you're buying into the platform for this saw.
- ✗Retail availability is Lowe's-centric in big-box stores, so hands-on comparison shopping is harder than for the big three brands.
Ridgid 18V Brushless R8657 Circular Saw
- ✓Standout value — $179 bare or $249 with a 4.0Ah Max Output battery and charger, well under equivalent DeWalt/Milwaukee saws.
- ✓Registered Lifetime Service Agreement covers the tool AND batteries for life — free replacement packs is a perk no other brand matches.
- ✓Genuine 15-amp-corded-class power: Pro Tool Reviews (8.0/10) found it powers through cuts far easier than the old Octane and fit for professional work.
- ✓2-9/16 in depth of cut at 90° and 1-7/8 in at 45° out-cuts most single-battery rivals and clears stacked 2x at square.
- ✓Full feature set with nothing missing: electric brake, LED light with dust blower, integrated rafter hook, and a vacuum port accepting 1-1/4 in and 1-3/4 in hoses.
- ✓8.8 lbs bare is light for the power class, and the aluminum shoe holds up to jobsite abuse.
- ✓56° bevel with positive detent stops covers rafter and stair stringer angles.
- ✓4.5/5 across 380 Home Depot reviews, with owners repeatedly saying it 'mows through everything' the Octane stalled on — and it runs on every Ridgid 18V battery ever made.
- ✗Home Depot exclusive — one retailer controls pricing, stock, and clearance timing.
- ✗Needs Max Output 6.0/8.0Ah packs to deliver the corded-class claims; on small packs it bogs in dense material.
- ✗Pro Tool Reviews dinged the plastic lower blade guard as feeling flimsy next to metal-guard competitors.
- ✗The overmold grip has less cushion than the old Octane model.
- ✗5,400 RPM trails the 6,000 RPM class leaders slightly in raw cut speed.
- ✗Lifetime Service Agreement requires registration within 90 days and isn't transferable — miss the window and you get only the 3-year warranty.
- ✗Ridgid's 18V line skews prosumer, so there's no track compatibility, connectivity, or rear-handle-style torque option in this saw.
- ✗Resale value on Ridgid tools is weak compared to the big pro platforms.
