This type requires a heavy-duty circuit because it’s driven by a powerful 3 to 5HP motor. The blade is driven by three parallel V-belts which ensure a smooth operation and an efficient transfer of energy. Needless to say, if you have big plans, you might want to consider investing in a high-quality cabinet saw. Prompted, it’s going to cost you a significant amount of money, but it pays out relatively quickly.
The RK7241S has two sturdy tubular legsets that fold down and lock, and one becomes a convenient handle for transport. The stand stayed put during heavy ripping operations, and lawnmowerstyle wheels make the tool easy to roll. But, once set up, you have to drag or lift the saw to move it, unlike other portables that keep the wheels on the floor during use.
Another important safety feature to consider is a magnetic switch. Magnetic switches are there in case of power cuts or outages and will also protect the table saw motor from over load. Effectively it will switch off the power supply the instant the power goes off ensuring you don’t have a saw blade spinning away in the dark! As you can imagine this is a very useful and must have safety feature when looking to purchase a new table saw.
If you’re going to be transporting your unit regularly, you should aim to keep weight to a minimum. Look for something lightweight, with convenient carrying handles, or a stand that can be wheeled around dolly-style at the worksite. Conversely, if you’re only going to be using your portable saw occasionally, you can probably stand a bit more weight.
If you’re a home DIYer or pro working mainly from a shop, you may have a wide table or countertop big enough to use the saw without any accessory stand. We would caution against working on sawhorses, though, as they can be wobbly and unsafe. It’s far better to spend a few extra dollars on a sturdy stand than to take risks with a rickety, improvised setup.
The safety brake feature is a real step forward in engineering, but it does have a few downsides. The aluminum brake works with single-use cartridges, so you’ll have to replace the cartridge if you trip the sensor. Likewise, the impact of the brake, stopping the blade in milliseconds, will destroy your blade, so you’ll have to replace that as well. It’s a small price to pay for keeping your fingers or limbs, but it’s probably a good idea to stock up on cartridges and blades
Paul – Good catch….I’ve updated that to say Skilsaw not SawStop…thank you! As you can imagine…all the data makes it tough to keep it all straight. I’m not even sure how you’d install that aftermarket fence on these saws. If you do I’d love to see how!! Those really look like they are made to install on cast-iron full size saws. I’d choose the DEWALT with a slight edge over the SKilsaw.
Other features include a battery-powered laser for lining up cuts. I found it to be pretty dim under bright shop lights and not lined up correctly with the blade. It is non-adjustable. A pullout rear extension provides some added support for long rip cuts. Rockwell also offers a couple of unique accessories: a sliding miter table ($179.99) and a power planer-style “Finisher” ($129.99). It mounts on the saw for flattening board edges.
We really should point out a big deal here and that’s the SawStop. It’s hard to put a price on safety and while the SawStop costs more than 3 times what the Hitachi costs it does offer safety that no other saw in test can offer. For those that can afford the additional cost that feature alone may tip the scales for you. Regardless of price SawStop came in 5th place for the categories we evaluated.
You’ll want to look for metal framing, and a design which allows for all the most delicate components to be stored inside the tool’s body. If you’re a DIYer who won’t be travelling with your saw often, you probably don’t need to worry about finding such a heavy-duty frame. Many portable units will fit easily on the passenger’s seat, so you won’t have to deal with wear and tear so much.
IMPORTANT REVIEW UPDATE (10/4/2016): After doing some additional testing with pressure-treated lumber and heavier stock, we [initially] found some issues with the Bosch REAXX saw that we couldn’t explain—except to say that it didn’t have the power we expected for cutting through denser wood. The blade exhibited a significant drop in speed during many common ripping cuts, and it even stalled out entirely at other times. We contacted Bosch and worked directly with them to determine the nature of the issue (which appeared to have to do with the saw’s electronic speed control). Here is the initial statement from Bosch on the matter:
This blade shares many features that come standard on other Diablo blades. The carbide teeth are cut from Diablo’s TiCo High Density Carbide. Perma-Shield non-stick coating helps the blade move through material with less friction, reducing heat that can lead to warping in addition to corrosion. Diablo’s Tri-Metal Shock brazing process ensures the teeth stay in place much longer than other blades and can withstand impacts that leave other blades in need of a dentist.
If you’re a home DIYer, dust collection shouldn’t be a big worry. You can always hook the saw up to your shop vac, but if you’re only working with it occasionally, you’ll be fine to simply get your sawing done, and clear the exhaust port afterward. However, if you’re working on a professional jobsite, you should plan to collect at least most of the dust from your portable table saw via a vacuum system.
And finally, there are a couple of jobsite table saws running around with flesh detection to drop the blade out of the way if it detects a strike. There’s a significant premium in cost for these saws and there has also been plenty of litigation regarding whether it should be required on every table saw and whether more than one company has the right to manufacturer the mechanism. But they’ll save you a much worse injury in the event of an accident.
You want to rip down lumber with your table saw. For this you’ll need a fence. You just can’t make an accurate rip cut without one. Check the fence sits on the rails firmly. You should be able to adjust it easily in both directions. A T-square fence is the most common type. Made from welded steel, it’s precise, user-friendly and durable. Some fences are mounted with bolts. Others are welded onto the head of the T-square. Miter gauges are priceless for making cross-cuts and other more advanced cuts. This gauge acts as a guiding device. It moves in the miter slot. You can angle between 45 degrees and -45 degrees. For angled or square cross-cuts or other specialty cuts, a miter gauge fully delivers.
The price is acceptable. One cannot say it’s a cheap piece of equipment because it’s not. But, the high quality of production and a great deal of precision justify the somewhat premium price. If you’re a devoted professional, the price shouldn’t be much of an issue for you. The only downside many people reported is the quality control within the company. Many models came with broken or missing parts.
It’s powerful. The blade is hooked up to a 3HP motor which can muster a no-load speed up to 4000 RPM! That’s perfect for all your cutting needs, and it’s much better than other inexpensive units when it comes to slicing hardwoods or thicker stock. While many smaller units advertise similar HP ratings, this one actually lives up to the promise, since it uses 220V power.
It also has the highest blade speed. This model has a similar 15-amp motor to our other recommendations, but it’s geared for maximum efficiency. The result is a blade speed that’s nearly 1000 RPM better than the Bosch or the smaller Dewalt. Reviewers marveled at how powerful this one was compared to the size of the motor, which seems underwhelming from the outside. It rips right through oak, cherry, and other planks with no lag or burnout. In fact, we’re hard-pressed to find something this would struggle to cut, provided you equip it with the proper blade.
Ergonomics is the science of designing and producing tools that improve a worker’s efficiency while reducing discomfort, fatigue, and risk of injury. Ergonomically enhanced tools can include helpful features such as angled handles, riving knives, safety switches, and non-slip coatings. Whether you’re shopping for ergonomic tools or just trying to select the right one for the job from an existing collection, the key things to consider are whether or not the tool eases your work and prevents you from straining in ways that could lead to injury. Ergonomic guidelines in tool design can help maximize human performance on the job by making the job easier for the worker, improving safety and decreasing injuries.
The DEWALT DW745 and the Bosch 4100 both have 15 amp motors, so power shouldn’t be a problem with either of these job site table saws. The DEWALT has a high torque motor that is capable of delivering a no-load speed of up to 3,850 rpm. The Bosch 15 amps and a no-load speed of up to 3,650 rpm. The difference between the two is not something that would be noticeable without sophisticated equipment, and will not affect performance in any significant manner. The noticeable difference between the two is that the Bosch 4100 comes equipped with a soft start motor that is lacking on the DEWALT DW745. This will cause a noticeable load on your power source, and may affect other tools and lighting attached to the same source during startup.
Plus, the machined aluminum table is our favorite on the market right now. It also has a smarter motor system than either of the Dewalt’s, thanks to a soft start and automatic speed control to ensure smooth cuts. However, it’s the slowest of the pack, and it doesn’t have quite as good a fence as the yellow competition. We think it’s a great choice for pros who are concerned about accuracy, but can’t spend lots of money on their unit.
One thing you must be aware of with a contractor saw is the fact that they can be a lot more difficult to move from job to job, this is something that must be considered before purchasing. For thicker and harder type woods a cabinet table saw maybe the best way to go, especially for the long-term benefits, but for the average mid-sized contractor it’s still a great option. Read More
