Frequently Asked Questions
+ Can this tool really replace my pneumatic die grinder?
Yes. The 3485-20 is designed to match the power of a 0.3 HP air tool. It provides more consistent torque and eliminates the need for air hoses, making it faster to deploy on the job.
+ Which battery is best for this die grinder?
For the best balance of power and runtime, we recommend the M12™ REDLITHIUM™ HIGH OUTPUT™ CP 2.5 or the XC 5.0. These batteries provide the high current needed for heavy grinding.
+ What accessories can I use with the 1/4" collet?
The 1/4" collet is compatible with all standard 1/4" shank accessories, including carbide burrs, abrasive stones, and sanding discs.
+ Does it come with the wrenches for changing bits?
Yes. The bare tool includes the necessary wrenches to securely tighten and loosen the 1/4" collet.
