Ask just about any carpenter about the utility of the oscillating multi-tool and heโll tell you that heโs not sure how we all got along without it in the โoldโ days. For flush cuts, plunge cuts, sanding, grinding, polishing, removing, and much more, the oscillating multi-tool is nearly indispensable on todayโs jobsite. Like most power tools nowadays, todayโs multi-tools have made the leap to battery power, but there are some reasons to keep a corded version around. I intend to get a lot of work done with the Bosch StarlockMax Oscillating Multi-Tool as we build a home in a development in Polk City, Florida.
Bosch Starlock Advantages
The perennial problem and danger of using even the best oscillating multi-tool has been the need to change the blade soon after a cut. You remember very quickly that friction generates heat. Lotโs of heat. And letโs not forget when your fingers are around the teeth. Multi-tool manufacturers each have their own takes on blade change mechanisms, but whether screws hold them in or levers clamp them down, at some point in the process you have to touch the blade. But Bosch and Fein seem to have finally solved the problem with the 3-D bottlecap interface of the Starlock system.
Working the Starlock System
A lever closes the Starlockโs two small jaws, which are then pushed through the hole in the blade, and pop! The jaws automatically spring open to hold the blade securely. When itโs time for a blade change, pulling the lever closes the jaws and the blade falls off of the tool. No fingers were harmed in the making of this blade change because they never touched a blade. Whatโs more, so many points of contact between the blade and tool should result in more torque transfer. Weโll see how it goes.
Other Noteworthy Features
Theย Bosch StarlockMax Oscillating Multi-Tool also packs quite a punch with a 5.5-amp motor. A variable speed dial modulates the oscillations per minute between 8,000 and 20,000. The blade moves in a 3.6ยฐ arc, which might not sound like a lot, but at several thousand oscillations per minute, it can do a good bit of work.
It also boasts Boschโs Constant Response circuitry which is designed to keep the power constant even under load so thereโs no bogging down. And if you have to be tethered with a cord, the ball-joint cord swivel is a nice touch. It all weighs in around 3.5 pounds. Hey, weโve got a house to build here, letโs go!
Bosch Starlock Multitool Performance
This tool can do just about anything. I mentioned before that thereโs still a reason to have a corded multi-tool in a sea of battery-powered ones, so let me give you an example. Say you need to put in a wall unit because plans changed mid-stream and the tradesmen before you didnโt know they should frame for it โ or maybe they just forgot.
Just about any multi-tool can make quick work of the drywall, but sometimes thereโs a stud right where that wall unit needs to go. Battery-powered multi-tools can struggle with the stud, but the Bosch StarlockMax Oscillating Multi-Tool didnโt break a sweat in 2x4s. It just about doubled as a reciprocating saw. Itโs thatย powerful. It eats straight through studs. In fact, I had to dial back the power just to keep control of it for shorter, finer cuts.

More to the point, I had to cut an electrical box into the side of an island in the kitchen. For rougher work, precision isnโt as big of a factor, but for something like this, youโve got to be right on it. I had to turn the power all the way down to have control of it. The tool did a fine job, but it revealed one thing โ at this speed, it isnโt really any quicker than a battery powered multi-tool.
So one thing to consider when youโre deciding on what type of power source you want is the type of work you typically do. If itโs finer, precision work then youโll probably do just fine with a battery. But for an all around multi-tool from small work to demolition, this model has all the power youโll need. Like I said, itโs nearly as good as having a reciprocating saw. Pretty impressive.
But it is funny how perceptions have changed โ we used to doubt the usefulness of the battery power and rely on the corded tools. Now we tend to avoid the corded tools unless absolutely necessary!
The Starlock Connection and Blades
The Starlock system is really efficient and easy to use โ itโs the best blade system Iโve seen on a multi-tool. You use the lever to pop the old blade off and snap the other on. Itโs a quick, done deal. One of the nice things about this model is that it accepts Starlock, StarlockPlus, and StarlockMax accessories. Hmm, the naming system sounds vaguely familiarโฆ anyone seen my rotary hammer?
The soft material blades from the kit arenโt terribly impressive in my experience. The main issue is they donโt cut a straight line well as other blades I use. If youโre just doing a rough opening in soft material and the hole will be covered with something larger, then itโll be just fine. They will excel at taking silicone out of corners or some similar job. Just be cautious on finished material.
The scrapers work very well, however. Just take a look at each kit before you buy and be sure youโll actually use all the included blades. For some Pros, youโll be better off buying the individual blades and accessories you need.
The Bottom Line
The Bosch StarlockMax Oscillating Multi-Toolย is just a great tool. The question is whether the work you do requires so much power in a multi-tool enough to justify the cord. Itโs possible that battery power is sufficient. But if you want an all around, soup-to-nuts tool that handles the fine as well as demo work, then you wonโt be disappointed for one minute with the Bosch.
Itโs right at home doing finer, precision work at slow speeds and demo work at high speeds. Itโs like a wild stallion near 20,000 RPMs, so be sure you have control. It can almost double as a reciprocating saw in some scenarios. Some of the impressive performance is undoubtedly due to the power transfer of the Starlock system, which is the best multi-tool blade system Iโve seen.
On its own, the multi-tool is $259 and has accessory kit options that run it up to $399. Thatโs a pretty big price for this class of tool, even for Bosch. What you get for the premium is the Starlock connection system. The build quality ensures that the tool should last, so itโs a convenience feature many Pros will want to consider pulling the trigger on.
For lighter duty stuff, you might stick with battery power, but if not, theย Bosch StarlockMax Oscillating Multi-Tool is a stellar option if you can afford it.
