The bits/blades for the Dremel Multi-Max fit the Harbor Freight clone
Furthermore, the Dremel package says the bit also fits:
* Fein Multi-Master 636
Bosch Multi-X PS50
- The wood-cutting blade from Dremel retails for $13.32
- A 3-pack of similar blades from Fein retails for $105.08 ($35.03 each)
- The Bosch machine uses Fein blades
- The Harbor Freight Multifunction tool wood-cutting blade is $5.99 with two
free scraper blades.
So, then, one permutation is a $6 HF blade instead of the $35 equivalent in
your Fein tool.
