Not glue ready. The edges produced with plunge-cut saws are clean, but in the rake of the light, small saw marks can be seen.
All aboard. Plunge-cut saws work best when slid along a guide rail or track. What saw works with which track is interesting.
Properly set. A plunge-cut saw is set up with the blade slightly canted at the front. Here you can see the paper-thin gap needed to make a saw work its best.
Stays on track. On the Makita, a small lever slides a catch into an undercut groove and does something
that no other track saw can do – stay hooked to the track when all the weight is tilted.
A tale of two levers. Flip a lever to bypass the 45º stop and cut at the maximum-cut angle of 48º – or push in the twin tabs to drop the saw to cut at a negative angle. These are two features that are unique to Makita’s saw.
Spring to action. A spring-loaded roller locks the DeWalt saw to a DeWalt track. This is a great feature
if you’re using this saw as a panel-cutting tool.
Quick-change artist. Festool’s saw is by far the easiest on which to swap out blades. It’s a one-handed operation.
Plunge-cut Saws
May 12, 2009
by Glen D. Huey Right on track. The commonality of these saws is a guide rail or track on which each slides – as well as the clean, straight cuts produced. Where differences show is in the unique features found when given a closer look.
Since DeWalt and Makita entered the United States plunge-cut saw market with Festool, the three have received immense interest and discussion. How are the saws different? Are the results of a crosscut or rip cut any cleaner than those made at a table saw? What features are common or unique on plunge-cut saws? I scrutinized a DeWalt DWS520, a Festool TS55 and a Makita SP6000 to see which, if any, of the saws stand out.
If you’re looking for vast differences in the cuts produced by the various plunge-cut saws, I’m afraid you’re going to be disappointed. I used each saw to cut plywood and hardwood, both with and across the grain, and for slicing samples of melamine. There is a small amount of tear-out (mostly across the grain as you might expect), but nothing significant. In fact, I compared those cuts with cuts made in the same materials at a table saw and again, the differences are minimal. A Smooth Ride But here’s what is attention grabbing: All three plunge-cut saws ride and operate on a Festool guide rail. However, Festool’s saw rides on a Makita track, but not on a DeWalt track. And a DeWalt saw doesn’t work with a Makita track just as a Makita saw is not functional on a DeWalt track. Need a scorecard? How Plunge-cut Saws Work What makes these saws operate as they do is the blade set with a “toe-in” design. This allows the saw to cut at the front of the blade with the back of the blade held away from the freshly cut edge. Minimal burn and little tear-out on the money side of the cut is the result. This is also the major difference between the finished cuts from these saws and those of a circular saw when used in combination with a straightedge guide. There are other features common to these saws, such as track adjusters to dial in the exact fit for a smooth slide, a lockable arbor for quick blade changes as well as blade depth-of-cut adjustments. And each saw is set up for dust extraction via an external vacuum. (See page 53 for more comparisons.) A significant feature found on the DeWalt and Festool saws, but not on Makita’s saw, is a riving knife. At first, you may question a riving knife’s importance because the blade retracts into the saw if the tool is lifted from the track. But even with that action, there is still an opportunity for kickback and a riving knife defends against that action. Features – Makita SP6000 Another unique feature of the SP6000 is a slide lever that, when engaged, hooks into an undercut groove in a Makita guide rail to keep the saw from tumbling off the rail when set to cut an angle, but only on the Makita track. Features – DeWalt DWS520 A unique feature found on the DeWalt saw is an anti-kickback catch. Release a knob and a small spring-loaded wheel, located in the center groove of the saw’s base, is thrust against the track preventing backward movement. But this feature only works on the DeWalt track. (On a Festool guide rail, the DeWalt saw’s center groove is not utilized.) Features – Festool TS55 Also, the Festool saw is part of a woodworking system and there is an extensive number of accessories available for this tool. A Total Toss-up Click here for PDF file.
