Dremel 709-02 mixed accessory kit
Dremel 709-02 groups 110 accessories across several jobs.

How to choose
Compare the specific sanding carriers and screw mandrels you will use. The full case has more value when you need several types of accessory than when you need one known refill.
Compatibility and limits
110-piece kit · documented 401 and 402 holders with several band sizes
Questions before buying
What if the accessory I already own needs an EZ Lock mandrel?
Check the 709-02 contents against that exact holder requirement. The 710-08 lists an EZ402 with conventional holders, making it the kit to compare when both interfaces matter.
