Bosch JS572E and JS572EB Jig Saws
This month I put Bosch’s relatively new Swiss-made jig saws through their paces. The Bosch JS572E Handle Grip and Bosch JS572EB Barrel Grip were shown off to us at the Bosch media event, and we had wanted to get them in for a closer look ever since. Either saw is available as a standalone tool, or in an L-Boxx storage case at a street price of just under $250 and $300 respectively.
In 1946 Albert Kaufmann, who worked for the Scintilla AG Company in Solothurn, Switzerland invented the jig saw by replacing the needle of his wife’s sewing machine with a saw blade. Bosch acquired Scintilla in 1954. Further Bosch innovations came in 1666 with the orbit (pendulum) action which drives the blade forward with each stroke, and in 1989 with the tool-less blade change. Bosch also invented both the double tang and the T shank. These two new tools only serve to increase Bosch’s jig saw bragging rights.
The two tools are essentially identical engines in two different housings. This brings up the decades-old argument of top handle verses barrel grip. The argument for barrel grip is that the lower profile gives better control and visibility of the blade. The detractor’s say that the design runs hotter, lacks variable speed and does away with the quick start and stop that the top handle affords. A common wisdom found in discussion groups is that people with larger hands tend to prefer the barrel grip. Europeans also seem to chiefly prefer the barrel design while the top handle is more popular in England and the U.S. Cutting to the chase: the choice is yours.
The Whole Kit and Kaboodle
Both tools can be purchased as kits and will then come packaged in Bosch’s new L-Boxx, which look strikingly similar to Festool’s Systainer Box System, though it’s manufactured by a different company. Made from high grade plastic, the L-Box is rugged and leaves a much smaller footprint than the average blow-molded plastic cases we have seen from power tool companies. The cases latch very nicely and snap together after you remove the four plastic shipping clips from the bottom. Storage for all of the accoutrements (including 10” blades) was well thought out. Great job Bosch—let’s see more L-Boxxed Tools!
Bosch JS572E Jig Saw Use and Features
Both saws worked superbly and were easy to use. I appreciated the ambidextrous nature of the Bosch JS572E, which allowed you to use the trigger lock with either hand. Both jig saws had a tool-less blade eject system that worked well. Anyone who has suffered third degree burns trying to manually remove a blade with their hands can relate to the importance of this feature. Both tools allow you to easily square up the base in a way that is both intuitive and simple, and the blade is really well lit thanks to dual LED lights that bathe the cutting area with light. Finally, the dust collection on both tools is something that I found to be beautifully executed. Connected to my shop vac, very little dust escaped as I was making my cuts.
A Visual Tour of Helpful Features
If you are left handed you will love the Top Handle’s left or right lock for the trigger. The barrel grip switch is controlled with the right thumb only, however.
Tool-less blade change in both tools was nothing short of superb. Simply pull out the lever and press the blade down. The last 1/16” is spring loaded so requires some downward pressure before releasing the lever. The spring spits the hot blade out of the tool when you raise the lever so that you do not burn your fingers. Two LED lights also lend nice visibility to layout lines during cutting.
Squaring the base is simplicity itself and requires only a screwdriver. Insert a blade with the splinter guard in place. Now insert a second blade in a cutout in the guard and you can instantly adjust the base to be dead square. Adjustment is via a screw in the center of the base just behind the blade.
There is superb lighting around the blade thanks to two LED lights. Many wonder why there is a switch to turn the lights on and off. The reason is that most Europeans use the tool upside down because they can see the blade and follow layout lines better, and there is no tear out of the wood grain on the face. Although I am demonstrating with the Top Grip the Barrel Grip is much better for this scheme and is partially responsible for its popularity in Europe.
Both tools came with superb dust pick up connections. An articulated plate snaps in from the rear of the tool. A tool-triggered vacuum can either be attached directly or with the supplied adaptor depending on hose diameter. The user manual claims that the dust shroud must be in place for best results. I did not find that the shroud made much of a difference. With or without, a good amount of shavings end up on the floor, but all fine dust is sucked up. How much shavings end up on floor is largely dependent on the blade being used.
Excluding “none”, there are three orbital (pendulum) action settings, which are selectable through a switch on the left side of either tool. I mostly used position II or III. You turn orbit action off for cutting metal, but even on more delicate cutting I found orbital action to a helpful with the proper blade. There are double rollers on the blade guide which stoutly support the blade as it cuts.
While the tools both have a die-cast aluminum footplate, both also come with a very nice plastic no-mar shoe that is perfect when working with delicate surfaces. For more rugged use there is also a steel “overshoe” that slides over the plastic base and snaps into place. A consumable splinter guard also snaps in place and reduces tear out, especially in plywood. It only works at 90 degrees and does not work at all when the steel overshoe is installed. Base angle adjustments are tool-less. Simply raise the red lever on the right side and swivel the base to the desired angle.
It’s What’s on the Inside that Matters
Both tools are double insulated, draw 7.3 amps and have a soft start motor. Bosch uses something it calls Constant Response Circuitry that keeps speed constant with changing power needs, so if you start to run into a more difficult part of the cut, the motor responds with additional power to get you through. There is a dial that regulates speed from 800 to 2800 strokes per minute in 6 increments. With the top handle model, speed is further regulated with a variable speed trigger. I really appreciated the better-than 13-foot long SJ-style power cord because I can use this tool anywhere in my shop without an extension cord. The instruction manual was also very clear and easy to read, and I rate it an 8 out of 10.
Bosch offers a gaggle of their Swiss Blades for a wide variety of applications. The top blade is 10” long offering bayonet saw utility to a jig saw.
With the 10” blade either saw cut through a dry 5” square of white oak in 29 seconds.
Plunge cutting with either style grip was fast and assured.
I found both tools a joy to use and wish I could keep both. Which style you choose is up to you.
In my use tests both saws gave outstanding performance. With the 10” blade I was able to cut through dry 5” square white oak post material very quickly. The cut was true and square, making this tool (in either form) suitable for cutting the shoulders of tenons in post and beam construction. Although I did not try it with the 10” blade, plunge cutting was very assured with all other blades I utilized (including wood, hardwood, PVC and laminate blades). Scrollwork with either style machine was a joy with good illumination, fast and square cutting and good control. Having used them back-to-back I am not sure which I like better. I like the speed control, easy stop/start and cooler handling of the JS572E top handle. But I also like the slightly better visibility of the cut and better control when cutting from below afforded by the JS572EB barrel grip model. Chances are you already know which one you prefer—just know that both perform equally well with an almost identical feature-set. As a result, I can give both these tools my unqualified recommendation.
