TS 420 STIHL Cutquik®

TS 420 STIHL Cutquik®
A 14” cutting wheel puts this cut-off machine in the big leagues of performance, efficiency and ease of use.

Product Description

The TS 420 is so popular, it could possibly be called “the standard” to which other cut-off machines are compared. Users like it because it is compact, lightweight, reliable and proves itself day in and day out, all day long. The TS 420 features all the high-performance features of the TS 410 – including an X2 air filtration system for a clean and smooth-running engine and virtually maintenance-free filters. With the added benefit of a 14” cutting wheel, it will handle cuts up to 4.9 inches in depth. This cut-off machine backs up its larger cutting capacity with a ton of usability features.



NOTE: Abrasive wheel included. Diamond wheel (shown) sold separately.

Model Features

  • Reduced-Emission Engine Technology - Caring for Nature
    The STIHL Inc. “Caring for Nature” seal identifies its powered products that are more environmentally conscious, producing zero or low exhaust emissions. STIHL Inc. defines “low exhaust emissions” as being cleaner than EPA and/or CARB exhaust emission standards.

    More information

  • X2 Air Filtration System
    The X2 Air Filtration System revolutionizes the cut-off machine industry by allowing air filters to last up to a year, based on cutting conditions. Outside air enters the system in a swirling motion, removing 80% of dust particles. This pre-cleaned air is then routed through the primary and secondary air filters before being sent into the engine. The X2 Air Filtration System is virtually maintenance free and maintains an incredible 99.96% cleaning efficiency.
  • Anti-Vibration System
    STIHL has developed a system for minimizing the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.
  • STIHL ElastoStart™
    The ElastoStart™ starter handle is a feature of STIHL. It is a starting grip with a built-in shock absorber that helps reduce the effort when pulling on the starter cord. The ElastoStart™ starter grip noticeably reduces the sudden peak forces (compression) normally felt during cranking. The forces which occur at the grip after the first compression stroke are smoothed out.
  • Semi-Automatic Belt Tensioning
    With consistent semi-automatic re-tensioning, this feature increases the service life of the belts and shaft bearings.
  • Ergonomic Grip
    The ergonomic top-handle bar design provides an optimal comfortable grip in any working position.
  • IntelliCarb™ Compensating Carburetor
    The IntelliCarb™ Compensating Carburetor is designed to automatically adjust the air/fuel ratio when the air filter becomes restricted or partially clogged and maintains the engine’s correct RPM. IntelliCarb™ uses air from the clean side of the air filter to control the diaphragm and flow of fuel. As the air filter becomes dirty and less air is available for the carburetor, the IntelliCarb™ system adjusts the fuel flow to compensate for the decrease in air flow. This is in contrast to typical carburetors that utilize this air from the “dirty” side of the air box.
  • Bayonet-Style Fuel Cap
    Includes retainer for easy use, even with gloves on.
  • Water Connection
    Water connection with shut-off valve and quick connector.

Reviews

TS 420 STIHL Cutquik® is rated 3.9 out of 5 by 30.
Rated 5 out of 5 by from This saw will last until it’s stolen! We run our 420s on a daily basis cutting concrete. By far all employees and myself prefer this saw over its competitors. We own both and the Stihl wins every time. It’s very light weight and is good on fuel. My only advice is to have spare bolts for the muffler. It seems to vibrate loose on every saw we own. Other than that just feed it fuel and run it for years. Thanks Stihl for a fantastic product.

Rated 5 out of 5 by from Hands down , the best! We’ve been using and abusing the 400 s , 410s and 420s for 20 years now , cutting all types of materials but mostly masonry and concrete; when you do that on a daily basis with no maintenance at all ( we run them until they die and then replace them) and get a 2-3 years out a unit , you cannot rate this machines lower then 5 stars, top notch pieces of equipment.We won’t buy anything else , period.

Rated 5 out of 5 by from Great Saw! I love this saw. Cuts great and does the job. Sorta on the heavy side but you're cutting solid rock it shouldn't feel like a feather. Get it, you won't regret it!!

Rated 5 out of 5 by from Great saw I’m a fan I’ve worked for a big masonry company for a couple years and as an apprentice it was my job to make cuts for the bricklayers. This saw was by far my favorite, it out worked a huskyvarna. Has a better water hook up when your cutting masonry units. And can go a while with little to no maintenance. We abused the snot out of thease saws on big jobs and they just kept going and going. I’d usaly get a month or so out them. Before they broke due to sand getting in the gas tank. Great saw. I liked it so much I bought one for my self

Rated 2 out of 5 by from ts420 vs ts400 I'm a brick mason been using these saws for over 25 years the ts400 is far bettert than the 420 and 410. The key 2 your saws longevity is trufuel which is pre-mixed no ethanol and proper filter maintenance. I cannot stress the importance of changing your filters regularly and using good fuel

Rated 5 out of 5 by from Overall great saw. This things are expensive. I had a really old one that was having compression problems and would always cause the pull rope to break at the worst times. So I finally gave in and bought a new TS420. Like I said, they're very pricey. So far the saw runs great. Fires right up within three pulls when cold, and always on the first pull once it's warmed up. Only thing I don't like is it feel bogged down when the blade is fully plunged in concrete, which is why I'm giving it four stars for the power category. I do a lot of Versa Lok retaining walls, which are 6" tall blocks. I wish the blade on this thing could cut 6" deep, but it doesn't. You have to make one cut, then flip the block over and finish it off, which really eats up a lot of time when you're cutting a lot of block while building a wall. Definitely something I wish Stihl would consider changing in their design.
