Q: How does the Chain Saw Sharpener attach to the tool?

A: Simply unthread the end of the housing, called a housing cap on the rotary tool, and the Chain Saw Sharpening Attachment will thread on in place of the housing cap.

Q: Can this fit older tools?

A: This attachment works with the MultiPro®, Professional Tools, and the 400 XPR, and the Cordless Lithium Ion Tool. It does thread onto the end of the tool, and the threading on the older tools is different. Unfortunately, we do not have a safe way to adapt this to older tools.

Q: Which stone do I use for my chain?

A: Dremel® offers three different size sharpening stones that can be used with this attachment. We have a 5/32" stone (#453), a 3/16" (#454) stone and a 7/32" stone (#455). These stones are sized in the same way that an actual sharpening file would be sized. When in doubt, refer to the specific owner's manual for your chain/chain saw. They will be able to provide the proper recommendation for the size stone/file you will need to successfully sharpen your chain.

Q: What are the spacers for?

A: Obviously, the stones are different sizes. That puts each stone in a slightly different spot in relation to the guide on the tool. To eliminate that gap, spacers are needed to make up the difference.

Q: What are the gauges for?
