UNBOXING of the BRAND NEW Bosch GEX125-150AVE Random Orbit Sander
Posted by Mark Hunter - June 01, 2011
But what are its features? Is it going to look after your health on the job site? And what else do you get in the box? Read on...
I personally love sanders, as I've expressed before. I like my sanders to be robust, not just in the hand, but to the eye. I like a beefy profile to the sanders I use, and I also want to know that they're doing the hard work while I merely guide them across the area I'm sanding. And I want to be able to use my sander all day and then be able to hold a pint of cider in the evening without spilling it all over me due to "shaky-hand-syndrome".
Makes sense, right?
First off, right out of the box, you can tell Bosch mean business with the GEX125-150 AVE. It sits squat on the work surface, with a flared sanding pad connected to a 400W motor via, well, 4 screws by the looks of it.
What's actually going on is that Bosch have decoupled the motor housing from the sanding pad.
That space between pad and motor is like a cushion of air that's going to buffer and absorb the friction and vibration that your sanding application is creating.
So, while you grip the aggressively angled top handle, the sander won't pass any of its bad vibes onto you.
Simply put, Bosch are claiming less than 2.5m/s squared vibration. Therefore you're going to be able to work and work and work while staying within the legal limits.
The other main benefit of this sander, asides from the vibration controlled 400W motor (with variable speed dial), is the dust control.
This is yet another part of your work life that's controlled and monitored by the suits in Brussells. But they mean well. They have your future health at heart, after all.
Bosch have made sure you're going to be able to comply with regulations by fitting the GEX125-150 AVE sander with a "best in class" (at least according to Bosch) dust collection rate of 81% per 25 minutes of use. This is achievable by either fitting the supplied translucent, easy-empty, microfilter dust box. Or you can attach the sander to an external dust extraction system.
But how is the GEX 125-150AVE going to perform, now that we've got all of this health and safety stuff out of the way?
We've already mentioned the variable speed-controlled 400W motor. This is going to drive the sanding pad, and this is also variable. In the L-BOXX you'll find a 125mm pad, a 150mm 6 hole pad, and a 150mm Festool-type 8 hole pad. So, right away you've got a fantastic level of flexibility in terms of the sanding applications you can undertake.
The pad will oscillate at between 11,000 and 24,000 opm, while rotating at between 5,000 and 12,000 rpm which gives you great control over the type of sanding you can do, whether it's going to be sanding curved surfaces with the 125mm pad, big massive pieces of dirty wood with the 150mm pad, or adding a sheepskin cover to buff the car on a Sunday morning.
But as soon as you release the trigger the friction brake kicks in and stops the pad oscillating, allowing you to put the sander down on your worksurface immediately. Bonus.
Bosch are obviously really pleased with the GEX 125-150 AVE and we have to confess that we're impressed with it too. Big power, delicate on the lungs and hands, and flexible with the supplied sanding pads that come in the L-BOXX, too.
