GOP40-30C Oscillating Multi-Tool Kit

The Bosch GOP40-30C StarlockPlus Oscillating Multi-Tool Kit provides a tool that delivers the new professional standard in oscillating tool performance, providing the next-generation Starlock 3-D tool-accessory interface, 4.0 amps of power and advanced electronics. The Starlock interface has more contact surface area from tool to accessory for blade grip and torque transfer, delivering a better cutting, grinding, scraping or sanding experience. The 4.0-amp motor provides a top speed of up to 20,000 oscillations per minute, to finish off heavy-duty applications. A variable-speed dial allows the user to set the optimal speed for the task at hand, and Constant Response circuitry maintains the desired speed under load. The GOP40-30 is compatible with all of Bosch’s full line of Starlock and StarlockPlus accessories for flush-cutting, plunge-cutting, sanding, grinding, grout removal, scraping and more.

Greater Torque transfer for better performance

The Bosch GOP40-30 StarlockPlus incorporates a new cupped 3-D tool-accessory interface that provides more contact area versus the conventional flat OIS interface. The blade snaps on to the tool like a snow ski snaps on to a boot. This results in an integrated high-torque transfer, a better grip and greater accessory stabilization. This enhanced grip drives better power transmission from tool to the work surface. The new professional standard in oscillating tool systems, the StarlockPlus interface builds on Bosch’s heritage of innovation in professional tool-accessory interfaces, such as the SDS-plus and SDS-max concrete hammer-bit interface and t-shank for jig saw-blade interface.

Greater tool muscle for productivity

With a 4.0 amps of power, this tool is ideal for flush cutting, plunge cutting, sanding, grinding, grout removal and scraping. The GOP40-30 has a top speed of up to 20,000 oscillations per minute, producing fine cuts and fast task completion. It has a 3.0° oscillating arc for better accessory utilization and increased productivity. Reinforced gearing and metal gear housing provide optimal force transmission, durability and reduced vibration for increased comfort. The variable-speed dial allows operators to match the speed to the material and task, with a range of 8,000 to 20,000 opm. Its Constant Response circuitry allows the tool to maintain the desired speed even as the load increases.

Flexible positioning and better control

Designed to be the handiest tool available, the Bosch GOP40-30 weighs only 3.3 lbs. and measures only 11.4 inches long, making it compact enough to reach into tight spaces, such as corners. The tool also features a flexible accessory orientation with positions at every 30 degrees for customizable accessory positioning, and the ball-joint cord swivel also helps facilitate easy tool positioning. An LED provides illumination for dark areas. The GOP40-30 has an ergonomic design with a narrow 6.9-inch grip diameter and provides multiple soft-grip areas for better control and extended comfort. The rugged tool construction provides durability and less vibration.

Stay on task with no-touch accessory change

The Bosch GOP40-30 allows operators to quickly and toollessly change accessories, such as blades, to stay on task. Just snap in the blade, like snapping in a ski boot. Importantly, there are no losable parts, as there are on some competitor tool systems. A pull of the release lever allows the accessory to detach from the tool – no more fumbling with wrenches or touching hot blades. This system also makes it easy to reposition Starlock accessories in any of 12 positions.

  1. Dutchmann

    This is my second oscillating saw, the first was another manufacturers’ but no comparison in quality and power. This tool is top shelf, very strong, feels great in your hand with great vibration control. The saw just feels as if the blade and the saw are one so accuracy and control is really enhanced. I know Bosch makes another saw with more power than this model so unless you’re sawing very tough and thick materials all day every day, this one is extremely capable.

  2. My Opinion

    This is very well made tool, just like anything made by Bosch. Plenty of power for this type of tool. There is another one 5.5 Amp that I was considering, but after using 4.0 Amp not sure why would you need even more power.This tool costs considerably more that other OIS type tools. I’ve used the OIS multitool before and it was OK nothing terribly wrong with that one. No question this has less vibration and cuts somewhat faster but at the same time it is 2-3 times more expensive. I was never a big fan of cheap tools and generally found that cheap tools do not work as well and do not last.The only complaint is the cost of the blades. There is no way that a piece of stamped steel can cost $10+ to manufacture thus it has to sell for $20+. I worked for several years in the QA at a major manufacturer in the stamping operation. Stamping is extremely efficient and cost of stamped parts is in cents not in dollars. Spot welding two pieces does not cost much either.Hope that in-time we may have a more reasonable prices on these blades.

    Best tool I’ve added to my tool set. Handy to make custom cuts in various material. As for Bosch, always had great luck with the brand. It’s solid, doesn’t overly vibrate during use, sufficient speed control, and love the StarLock blades. Easy on and off.

  5. OutwestOutwest

    Ok, first know what you are getting: this is the latest in blade lock tech which both Bosch and Fein are doing: it is a no-touch on and off starlock system for these blades. It will not take the old OIS blades, and does not advertise that it will.What is confusing is that the OSL blades which work with this CAN be used on older Bosck multitools. So, there is blade compatibility backward, but again, the GOP40 will not take the OIS blades. The blade removal is absurdly easy: no more hex wrnech or tool to put blades on and off. They literally snap on, and with a turn of the lever, pop right off. Because of the numerous contact points of the blade connection, I am finding that the power transfer feels stronger and there is no slop at all in the blade movement. And you still have all of the angles of attachment too.The unit itself is a beast. 4 amp motor is top in its class, so there is no lack of power even at the lowest setting. The housing is bombproof, but fortunately the tool is fairly light at 3.5 lbs and feels good in the hand with significantly less vibration than cheaper units. Noise level is less than expected for a multitool. As for uses, just go on youtube. This tool is a lifesaver for doing your own renovation work. Just for removing old caulk, this unit was worth its weight in gold.If you are debating about this unit versus ones that still take OIS, I would note that OIS blades are alot cheaper and there are generics out there. However, I would expect that even the cheaper units will catch up with the new blade attachment system in a few year, so why buy into the old tech unless you are simply destroying tons of blades. In all, I am super happy with the GOP 40.

  6. Cigar Smoke

    This unit is quite a bit quieter than the unit I had before. Plenty of power and a variable speed at the back side of the tool. I love the led light since when your in a tight spot it is hard to see sometimes. Bosh has always performed well for me. Also the cord is nice and long, I think it said 3 feet but it is more like 10.

  7. Thomas W Schultz

    Use this in my business. Great tool, easy to use.

  8. Steve

    This tool has been a life saver for me with all of the projects around the house. I’ll give a quick example. I did natural slate tile in my recreation room, and while installing base moulding I noticed huge gaps between trim and floor because of uneven tiles around the perimeter. This little gem allowed me to shave high spots off the tile, which allowed trim to lay perfectly flat!! During same install, I didn’t like grout after it dried too bright. In about 30 minutes this tool had it all removed! I like the non abrupt, soft start feature. Tool feels very balanced in my hand, and has a very long cord which eliminates need for extension cord most of the time. One of my most important go to tools that I have!! No dislikes at all with this tool!

  9. funkyhuman

    It works perfectly, has lots of power!. Attachment mechanism works perfectly. I have no complaints.I am just sitting here, wondering why did I not buy this earlier. It is such a multi purpose tool. I use it for scraping, cutting, sanding, cutting off caulk etc. The uses are endless. Bosch quality cannot be beat.

  10. H. Putnam

    I have no idea how we lived without this super handy cool tool. I foresee a few other tools being “retired” out because this one replaces so many other tools. As a non-handy person, I did need to watch a few videos and my husband initially used the wrong blade/tool to cut some nails so we had to get a replacement blade, but easy to find and easy to get new blades which are color coded. In his defense the blade said it was ok for metal and it did cut a bunch of nails but then the teeth started to bend. But totally user error. Love how easy it is to use and lightweight.
