Fein MultiMaster MM 700 Max: problems, parts and running costs

Checked: 2026-10-17

Summary

The MM 700 Max is a corded 450 W oscillating multi-tool with a StarlockMax mount, a 2 x 2.0-degree swing and 10,000-19,500 OPM, and no failure pattern is reported for this specific corded model. The practical complaints are the large grip diameter, the 3.53 lbs heft and a price far above consumer corded tools. It costs nothing to keep running except accessories: it is corded, so there is no battery or charger, and the only recurring spend is proprietary StarlockMax blades, sanding sheets and rasps. At $249.95 (Home Depot, October 2026) it is a good buy for daily professional use, not for occasional homeowners.

Common problems and fixes

Price far above consumer corded multi-tools — $249.95 at Home Depot and $306 at Burns Tools (October 2026) against $45-80 for consumer corded tools; not a defect, but it is what prices out occasional homeowners. [4][3][9]
Accessories cost more than universal-fit ones — StarlockMax blades, rasps and sanding sheets are proprietary to Fein, and Pickarank lists “accessories add up” as a con for the line; the fix is budgeting for them from day one. [9][7]
Heavier than the competition — at 3.53 lbs it out-weighs consumer corded tools; a Garage Journal owner with five brands of oscillating tool calls it “heavier than the others”, beside a 3.3 lb Bosch GOP-40 in the same thread. [7]
Oscillator wear on much older MultiMasters — Garage Journal threads document broken fork/cam bearings after years of use on pre-MM 700 models; no failure rate exists for the corded MM 700 Max, but the oscillating mechanism is the part to watch, and Fein sells spare parts through its online catalogue. [8][11]

Parts and consumables

Top-kit accessory set (72296864090) — about 19 accessories: curved E-Cut blades, Precision BIM and Long Life blades, a carbide rasp, a rigid scraper, a Multi-knife, a segmented blade, a perforated sanding pad with 10 sanding sheets (grits 60, 80, 120, 180) and a dust extraction device; bought once with the kit, then replaced piece by piece as blades and sheets wear out. [1]

Yearly running cost

Not enough data for a yearly dollar figure. The tool is corded, so there is no battery or charger to buy; the only recurring cost is StarlockMax accessories — blades, sanding sheets and rasps — replaced as they wear, and they typically cost more than universal-fit equivalents. [1][9][7]

When it is a good buy

Home Depot lists the Basic kit (72296863090) at $249.95 (October 2026); Burns Tools lists it at $306; Lowe’s carries the Basic kit. [4][3][5]
$250-300 is justifiable for professionals who use the tool daily and need the StarlockMax interface, the tacho-held speed under load and the widest swing in Fein’s lineup; the Basic kit ships with one blade, so the real-world cost runs above the sticker. [9][4]
Above ~$300, buy the Top kit (72296864090) instead — at Burns Tools’ $306 Basic price, the Top kit with about 19 accessories is the better value. [3][9]
Occasional homeowners: Bob Vila’s October 2025 roundup picked a Bosch StarlockPlus kit as Best Overall, and Pickarank puts capable corded tools at $80-150 and consumer-grade ones at $45-80 — either is the better choice when the tool comes out of the cupboard twice a year. [10][9]
