What to know before buying

Listing details to confirm

Listing details are inconsistent: the title says 6 inch and 5500RPM, while the body gives a speed range but does not independently clarify the size, and the technical fields also list 15 A, 20 volts and 499.99 watts alongside battery power. The claimed 9mm eccentric design and Makita 18V compatibility are not independently confirmed. Check the selected listing for the exact configuration and compatibility before buying.
