I still remember the smell of pine dust hanging in the garage that Saturday morning when my cheap flush-cut saw finally gave up. The kerf pinched, the blade bent, and I muttered that word neighbors arent supposed to hear. Five minutes later a buddy pulled up, tossed me his Fein MultiMaster Top, and told me to quit whining. One slicesmooth, square, no dramaand I was sold.
So here we are. You want straight talk about this oscillating wonder. No corporate fluff, no glowing superlatives, just real-world facts sprinkled with the kind of tips you could pick up over coffee at the hardware store. Grab a mug, settle in, and lets dig.
Why an Oscillating Tool Changes the Game
Every trade throws curveballs.
- A nail buried in oak trim.
- Caulk stuck behind a toilet.
- Grout that laughs at your chisel.
- A drywall corner that refuses to line up.
You can swing a jigsaw, an angle grinder, or a flush-cut saw. Each workskind of. The fein multimaster top does it cleaner, faster, with less cursing. The side-to-side motion stays tight, the tool nose slips into places a circular blade never will, and vibration drops to a gentle hum.
Picture itplunge a blade between cabinet and wall, pull out a perfect rectangle, pop in a receptacle box, and move on before your coffee cools. Thats the draw.
What Exactly Does a MultiMaster Do?
Short list:
- Cuts wood, metal, plastic, drywall, cement board.
- Sands inside corners your random orbit cant reach.
- Scrapes old paint or hardened mastic.
- Grinds off grout without turning the bathroom into a dust storm.
All with the same motor body. Pop the lever, trade attachments, keep rolling.

MM 700 Max Top: The Brute That Still Keeps Its Cool
Power matters when you lean on the blade. This orange beast throws 450 watts on the input side and still holds speed when you plunge into maple. The metal gear head shrugs at heat, the cord stretches more than sixteen feet, and the Starlock Max mount sends torque straight into the accessoryno slip, no chatter.
What you feel
- Lower buzz in the handle, so fingertips stay awake.
- Faster cuts because the stroke never bogs.
- Quieter pitch than most big motors, though ear muffs are still smart.
Who needs it
Remodelers knee-deep in flooring, tile pros raking grout eight hours straight, or anyone who hates stalling halfway through a jamb.
AMM 700 Max Top: Same Punch, No Cord
Pop in an 18 volt pack and roam. Attic work, porch repair, crawlspace surprisesplaces where outlets play hide-and-seek. The AMM 700 keeps the Starlock Max interface, the QuickIN lever, the anti-vibe guts, yet never drags a cable across fresh paint.
Batteries ride on the AMPShare platform, so if you already swing a Bosch drill, youre golden. Charge time stays short, runtime feels long, and the kit usually drops two packs in the box.
Small gripe? The case layout could use a rethink, though foam inserts cure that fast.
MM 500 Plus Top: The Sweet Spot
Slide down to 350 watts and you still chew through red oak without blowing the breaker. Hobby cabinet makers love it, trim-out crews keep two on the truck, and homeowners appreciate the lighter price tag.

- Ease in at low speed, let the teeth bite, then crank it up.

- Vacuum alongside any sanding pad. Your lungs will thank you.

Frequently Asked Questions
Will my old open-hole blades fit?
Not directly. Starlock uses a closed interface. Adapters exist, though they eat power and introduce slop. Better to stick with Starlock steel.
How loud is this thing?
Think shop-vac on high. Wear plugs and carry on.
Can I cut nails?
Yesuse a bi-metal E-Cut blade. Go slow, let the teeth work, and cool the tip in a rag if it smokes.
Does cordless equal weaker?
Not here. The AMM 700 keeps pace with the corded twin until the pack asks for a charge.
Sanding drywall corners?
Triangle pad plus 120-grit mesh, low speed, light strokes. Feather the edge and move.
A Quick Word on Accessories
Starlock, Starlock Plus, Starlock Maxthree splines, one shape. Think of them like phone chargers. A Max tool drinks every accessory in the family, while Plus and base models top out at their own tier. If you crave the largest plunge blades, buy Max out of the gate. Otherwise, Plus covers ninety-five percent of tasks.
Real-Life Anecdote
Last autumn I rebuilt a century-old porch. Hidden under the decking sat nails thick as pencils and joists hard as stone. The MM 700 lopped off rusted fasteners flush to the beam, no sparks, no shudder. Neighbors leaned over the rail, asking if Id found some magic cutter. I shrugged, kept slicing, and finished before the first frost. Could I have done it with another brand? Probably. Would I have hit the same rhythm? Doubt it.
Final Thoughts
Tools either slow you down or speed you up. The fein multimaster top family sits firmly in the second camp. Choose the body that fits your workload, keep fresh blades nearby, treat the motor kindly, and you will slice, sand, and scrape with grin-worthy precision.
So go aheadtrim that jamb, rescue that tile line, carve that tricky outlet box. Once you feel the smooth hum and dead-on cut, you will wonder how you ever built without it.
