Dremel A679-02 Sharpening Kit: An Attachment Set for a Tool You Already Own

Owning a rotary tool does not automatically make it the right setup for a garden blade or chainsaw cutter. The attachment, abrasive and workpiece have to agree. Dremel's A679-02 sharpening kit is an option for someone who already owns a compatible rotary tool and wants a defined set of sharpening accessories rather than another powered machine.

This is an attachment kit. A rotary tool is not included. The three guides cover chainsaw, lawn-mower and garden-tool sharpening, but those task names are a starting point for compatibility checks. They do not establish that every blade or chain can be treated with the same stone and setup.

Start with the rotary tool you own

The current manufacturer page lists compatible Dremel models, including the 3000, 4000 and 4300. Read the model-specific information before ordering. Dremel's shop description states that the 4300 needs a collet and collet nut for this kit; a familiar brand badge alone does not settle the connection.

That check is central to the purchase case. The first reason to consider the kit is reusing a suitable rotary tool for several defined maintenance tasks, with purpose-made guides. Someone starting without a compatible tool must assess the complete setup and cost, rather than judging the accessories as if they were a self-contained sharpener.

The listing's component photo is useful here: it separates the guide bodies from the stones. Keep those small pieces organized with their instructions. Having a kit in the drawer is less helpful if the correct abrasive or spacer is missing when a particular job comes around.

Choose the stone for the actual chain

Dremel identifies four included stones by accessory number: 453, 454, 455 and 932. The chainsaw attachment also uses a gauge and the relevant spacer arrangement. The supplied manual explains that the chain specification determines the stone and setup.

The second buying reason is this defined combination of guide, abrasives and spacing components. It gives an owner something concrete to check against the chain's requirements, instead of selecting a generic grinding stone by appearance. That is a configuration benefit. The available documents do not establish a measured cutting-performance advantage.

Do not treat one chain pitch mentioned in a product description as universal. Consult the chain maker's specifications and the kit instructions for the actual chain. Cutter sharpening and depth-gauge work are different tasks; a guide for one does not establish that every part of the chain should be ground in the same way.

Mower and garden blades have their own limits

The manual specifies the 932 stone for the mower and garden-tool attachments. The blade must also fit the guide. Those requirements are more useful than a broad claim that any outdoor cutting tool can be restored by this set.

Before a mower blade becomes a sharpening project, its condition matters. The instructions distinguish sharpening from repairing a blade with cracks or missing material. A damaged blade may need replacement. Removal, reinstallation and balance belong with the mower's own instructions and the appropriate maintenance procedure.

This article is a buying assessment, not a substitute for those operating instructions. Follow the relevant tool's power-disconnection and handling requirements. The guides help define a setup; they cannot make an unsuitable or damaged workpiece suitable by themselves.

A useful kit when the recurring jobs fit

The A679-02 makes the clearest sense for an existing compatible Dremel owner whose recurring jobs fall within the three attachment types. Its appeal is the organized set of guides and matched accessories, with the scope of each task checked before use.

It is a weaker purchase when you lack the required rotary tool, rarely maintain these items, or prefer having blades serviced professionally. It also adds small parts and setup decisions to manage. There is no verified time-saving comparison here, and no claim that the guide guarantees an even edge regardless of technique.

Buy around your actual tool and workpieces. Confirm the connection, abrasive and blade or chain requirements first; then the kit can be judged as a specific addition to equipment you already own.
