The Bosch GOP40-30 StarlockPlus® OMT Review

The Bosch StarlockPlus® Oscillating Multi Tool Stands Up To Tests
This is my review of the Bosch StarlockPlus GOP40-30 oscillating multi tool. Up to this point, I have been using a Fein Oscillating Multi Tool at work and it’s been a mixed bag. I love the versatility of all the different cutting and sanding attachments, but have been frustrated by the way I have to deal with the screw every time I want to switch between them, and how loud it is and how much it vibrates. The model I was using came out back before any of the quick attachment technology rolled out so I was very excited to get to try out this new Bosch Oscillating Multi Tool because it specifically addresses those headaches.
The attachments of the StarlockPlus® Oscillating Multi Tool
This Oscillating Multi Tool has the new StarlockPlus design for attachments, where the blades can pop on and off in almost no time. To get one on, all you do is press it in place and the mechanism in the head of the tool snaps open, pinching the piece in a rock solid, locked position. To get the attachments off, there is a lever on the side of the head of the tool that swings out and the blade drops right off. Changing between attachments has gone from a minute long fumbling with lining up the pin and getting the screw in place, to under a second. Pull, drop, press. New attachment’s ready to go!
There are 12 different positions for a blade to lock into that make it possible to cut just about any material in any awkward situation. And the way the attachments connect provide a much more solid link – instead of just face to face and a few bumps to transfer the oscillating energy, the Starlock’s perimeter solidly grips around the raised connecting surface of any blade or pad you use. The attachments bed into the connection point, seating solidly into a tight fit. This set up has much more torque transfer, and it also seems to cut down enormously on the amount of vibration coming back to my hand. It’s a truly impressive improvement, and makes the tool so much more pleasant to use.
Here’s a video from the folks at Bosch Tools on how easy it is to change blades on the new Starlock system from Bosch:
The power of the StarlockPlus® Oscillating Multi Tool
The GOP40-30 also has a four amp, variable speed motor, compared to previous models’ 3 amp variable. It definitely has the power to do what is needed. I have cut through regular and treated 2x4s, nails, sanded through stain, and cut mortises straight through a 2×4, and there was never any loss of power during operation – just smooth, efficient cutting.
Another feature on this model is a super bright LED work light. It’s so bright, sometimes I wished I could turn it off! Sanding some ¾” maple plywood edges, the light would occasionally white out the little ridges and blade marks I was trying to getting rid of, but the way the grip is designed, it was easy enough to use my non-dominant hand to cover the light. That hand positioning worked well both to block the light and to provide extra stability for fine movements and precision work. It would be nice if the light could be turned off and/ or dimmed, but I’d rather have too much light than not enough light on a tool. The angle it was directed worked perfectly for illuminating just in front of the sanding attachment, so great for any work that the tool would be doing.
I’m not entirely sure, since I didn’t have one available to test out, but I believe there is also a depth stop attachment that can be added to this model. That would add an extra amount of precision and repeatability to cuts you could need to make. So, if that’s the case, that would be another great feature to this already versatile tool.
The main body of the Oscillating Multi Tool is a little thicker than I would have liked for holding it, it’s no deal breaker, but I think my hands are fairly standard size (I wear large size gloves typically) and the tool is just slightly larger than would be perfect for my hands. I think if I were having to use it all day, every day I would appreciate a slightly narrower circumference, but the balance and heft of the tool are great.
The only other thing I wish for was for the tool to be cordless. Bosch has cordless OMT’s, but not in the Starlock line just yet.It has a great, 13.5’ long cord, so it can easily reach anywhere in my shop, but cordless is just the way to go on pretty much anything these days, and not having to deal with a cord is always a plus.
Last thoughts of the StarlockPlus® Oscillating Multi Tool
Overall, I love this tool. Being able to switch between attachments in such a short time is a huge, huge improvement in the functionality of the Oscillating Multi Tool, and less vibration and great balancing make it easy and comfortable to use. I love the power it has and the variety of attachments make this a great tool to have in my back pocket. Thanks again to Bosch for letting me use and review their new StarlockPlus Oscillating Multi Tool. If you have any questions, don’t hesitate to ask!
