BUCKET BAG TEST: battery-powered jigsaw: big difference between how fast they are



[ad_1]

In 1946, the Swiss engineer Albert Kaufmann replaced the needle in his wife's sewing machine with a saw blade and invented the puzzle.

Today, there is a wide variety of puzzles from all major tool manufacturers. We analyze seven different models, from the cheap in the consumption class to the expensive and robust in the professional class.

Just as in 1946, the most important feature of the jigsaw puzzle is still a saw blade that goes up and down pulled by a crank mechanism. Most jigsaw puzzles now also have a mechanism called a pendulum. There is a small wheel at the bottom of the foot that pushes the saw blade forward when the blade is pulled up, and feeds it into the saw. This significantly increases the cutting speed and reduces the power required to push the cabinet forward. The offset is suitable for sawing wood construction, where it is not so careful that it tilts a little. The degree of displacement can be defined in several steps. If you use sawmill for metal and for very nice cuts, the pendulum must be turned off.

Different grips – unique features

There are two main ways to build puzzles. Some have a handle in the shape of a rim that makes them comfortable to carry. Others are built with cylinder claws where tightening is the actual engine housing. It makes it considerably easier to cut from the bottom up, and grabbing at the top of the house gives in our view slightly better space for both hands to control the fairy tale. On circular saws it is necessary to grasp the front with the other hand if one wants to use both.

The disadvantage of the cylinder claws is that the motor housing may be large for small hands. Makita demands the best hands, while the Blue Bosch has the narrowest grip of the cylinder handle saws. However, the diameter is several inches larger than the rim saws.

All saws, except the Black & Decker and the green Bosch, have a plastic plate attached to the foot, which makes them easier to slide on the saws. Everything can be set to 45 degrees until each side is cut obliquely. Usually the foot gets a vision, but Ryobi, Makita and DeWalt have a lever that makes it much easier to set the angle.

One feature that only exists in Makita and Milwaukee is the autostart that allows the fairy tale to keep low numbers when initializing and then increasing when it is loaded. It's just beautiful.

When cutting along a line, there are many trimmings that tend to look at the line. There are two ways to fix this. One is having a vacuum cleaner, and some of the saws come with one that passes through or around the foot. The other way is to move the chip away, as do some saws directing the cooling air around the saw blade.

If the saw blade breaks or becomes worn, you should wrestle with a set screw before putting a new blade. All the saws in this test have a quick solution that allows the blade to snap instantly and be so easy to remove.

The saw blade is important

It is not enough with a good cause. For sawing effectively, you need to have a sharp blade tailored to the task.

– You need to think about what to do before choosing a magazine. And then you need to consider how beautiful the cuts you need. If you have seen wood construction be covered by veneers, efficiency is more important than appearance. Then you can choose a sheet that is stuck, that is, where the relatively coarse teeth are alternately bent slightly to the sides. Then you can rotate the puzzle at full speed and with maximum displacement, both through and through the tree's fibers, says Bosø district manager Børre Larsen.

If it's a matter of fine cuts, a completely different sheet is needed. So you should have a flat blade where each tooth is sanded as sharply as possible.

Thicker teeth, ie blades with low TPI teeth per inch number – are faster, but tear more material.

There are sheets adapted to most materials, not just wood. Some are made for specific metals and steel types, others for insulation mats, floor laminates or glass materials. There are also sheets with ceramic carbide teeth.

Most saw blades cut the material when the blade goes up, but there are also blades that cut down, like a hand saw. They are meant to cut completely without any glare from the side you have seen.

That's how we tested

To test the performance of the saws, we chose to cut two meters along the wood in 48 x 198 spruce wood. Each of the saws starts in a 10 mm hole at the end of the stroke with a maximum stroke in the pendulum. All saw blades received a new Bosch T234X saw blade.

Cases were advanced as quickly as possible. Based on the number of strokes, stroke length and pendulum movements, we expected differences, but away from the enormous difference we felt. The fastest saga in Milwaukee was only 3.5 times faster than Black & Decker's, and much more comfortable to work with. But of course also 4.3 times more expensive.

This test is at the extreme of what these cases are used for. If we saw many of these cuts, it would be preferable for a circular saw or a diving saw.

In practice, you'd rather use the puzzle for lighter work, and it should be curved. Here we have to highlight the blue Bosch which has created a separate guide shoe that can slide along a dipping saw rail to cut straight or use circles as a kind of adjustment. Ingeniously.

We did not test how far you get on a drums. So much because you've come a long way, even with a small battery, and because most realized that it's worth having some brands – so you can have more batteries and the same charger for many tools.

Consumer Tools



Black & Decker BDCJS18N: This is the cheapest, easiest, and slowest case of all. It does not have many functions but has a good grip and can be a good choice if you have small needs and other tools that run on the same battery.

Saga vibrates a lot when it is loaded, so avoid getting the saw in wood construction. This, on the other hand, is the only saw that has infinitely variable speed in the commutator. That's a good point.



Bosch green PST 18 LI: The green Boschen has been on the market for a few years, and this is noticeable. It's a bit faster, a bit lighter and a bit more expensive than the Black & Decker saga. In addition, it vibrates a little less.

We would like infinitely variable speed control, but here it is at full speed all the time. The grip is good and rubbery, and has working light and chip blowing.

Bosch also extended the green band's battery range to 6Ah. It easily conquers the orange competitor in the super low price range.



Ryobi R18JS7-0: This is new and has the best grip of all. Ryobi is marketed as a consumer brand but is twice as expensive as the other two. Because it was easy to score. This brushless saga impressed impressively after testing the first two. The formal flew through the wood and was faster than two of the pros, even the DeWalt story, which is also brushless. The powerful engine made a high impact and vibrated remarkably less.

The side angle of the Saga is adjusted with a lever. The speed is adjusted with the thumb of a continuous wheel. It has LED lights and comes with an adapter for extraction.

Ryobi has the advantage of having the most consumer tools in the same 1.5 to 9 Ah battery range. They have gone from 100 different tools, which makes it very attractive to standardize the brand. Great value for money.

pro Tools



Makita DJV181Z: Having let us impress by the Ryobi saga, we were even more impressed with the new brushless fairy tale for Makita. It passed in incredible 57 seconds with almost no vibration.

The price we found online was surprisingly low, but it's a campaign price and about 700 crowns cheaper than usual.

The Makita saga has an autostart, which we like very well. On each side of the house has a self-activated locking button and a start button.

But we would like to see a lever and not a screw to tilt the foot, and that came with a suction when it does not have bubbles. With a clamping diameter of 22 cm is not fair for those with small hands. Best value for money.



Bosch blue GST 18V-Li S: The blue Bosch saga we expected, but it's clearly characterized by its many years since it hit the market.

This is the only one of the professional models with brush motors and also the slowest. It may not be as strange as the shortest stroke length and the smallest stroke count. It vibrates a little.

On the plus side, it is lighter and has a smaller grip diameter, so it is easier to handle than the more powerful ones. And the price is the smallest among professional tools.



DeWalt DCS335N-XJ 18v XR: DeWalt also makes a new case. It can check all the features we want with some exceptions.

We like that it comes with suction and that has a lever for angled the foot.

Like the other of the faster models, this story vibrates little despite the load.

Saga is no brush, but no help. It is considerable after the two fastest. Even behind the Ryobi consumption model.



Milwaukee M18 FBJS-0X: This is the most advanced and fastest, but also the most expensive puzzles. Like Makita, it has autostart function and an electronically controlled switch on both sides of the box that makes it usable for both right-handed and right-handed. Switches switch on the machine when it is pressed for about one second to prevent it from starting. A new jerk stops immediately.

It comes with an adapter for extraction, but can also blow the chip with a separate switch. To adjust the angle of the foot, however, you must advance with the Allen wrench.

Milwaukee, like Bosch, has upgraded its batteries to 12 Ah but 5 Ah is much more suitable for that. Better on the test.
