How to Plunge Cut With the Bosch GKT55GCE

Posted by Toolstop Katy on 7th Feb 2013

In this short and simple guide we’ll look at how to easily perform a plunge cut using Bosch’s GKT55GCE 160mm Plunge Saw. The reason we’re suggesting this particular power tool is that it’s been specifically designed for plunge cuts.

So, rather than fumbling with a jigsaw or recip saw, Bosch have produced a saw that is precision made for plunge cutting, which is ideal for kitchen fitters, people working with laminate flooring, etc. In other words, if you need to regularly perform plunge cuts, this saw is worth taking a close look at. It’s going to slice through what you throw at it.

First off, and this is a given, remove the GKT 55 GCE from its supplied L-Boxx…

The GKT55 GCE is fitted with a precision saw blade specifically engineered for it by Freud Group.

Bosch claim it’s a "vibration and noise dampened" blade, and from seeing it in action, we can attest to it’s incredibly capacity for cutting straight, true and with no mess…aided by the machine’s dust extraction.

In our "how to plunge cut guide" we’re going to suggest you enlist the services of a good quality guide rail. This will obviously mean you’ll be cutting straight and true. We would recommend using the Bosch FSN800 Guide Rail.

There are a number of advantages to using a system like this, and we’ll outline them below, but the main one is that FSN series of Bosch guide rails and the GKT55 GCE plunge saw have been designed for each other.

Bosch cite the following advantages to using a guide rail like the FSN800:

  • Precise guidance – rails are exactly straight, even when the rail is extended, due to self-aligning connection element
  • Stable extension – due to the VEL connector for stable and quick connection of guide rails
  • Safe operation – anti-splinter guard for clean cut edges and adhesive tapes for non-slip handling

Ultimately, it’s up to you whether you use one or not, but as you’ll see in our video below, it’s well worth adding to your cut, particularly if your goal is to plunge cut quickly and accurately, frequently!

Mark up your work piece and our advice is to make sure you mark the start and stop points of the cut you want to make clearly and boldly.

The reason for this is that the Bosch GKT55GCE has marking on the saw casing and at the end of the blade that serve a visual indicator of exactly where the blade will start cutting and where the blade ends.

Keep a close eye on these marks when you line up your saw. The mark at the rear of the casing should be in line with where you want the cut to start. The GKT55GCE’s motor has soft start, so press in the safety trigger, and start to plunge.

Watch as the Freud blade drops down and slices through your work piece, the rear of the blade cutting exactly in line with your start part. Then easily glide the saw along the guide rail, watching closely for the red line at the front of the saw’s blade to match up with the line at the end of your cut.

Ease up on the handle, depress the trigger, and your plunge cut is complete.
