Dremel A679-02 Review: Pros, Cons and Who It’s For
A research-based look at the Dremel A679-02: a sharpening attachment kit for rotary tools with three attachments and four grinding stones, what the listing states and who it suits.
On this page
This Dremel A679-02 review comes down to one point: it is a sharpening attachment kit that turns a Dremel rotary tool you already own into a sharpener for chainsaw chains, mower blades and garden tools. The kit holds three attachments, four grinding stones, a gauge, spacers and a wrench, and it fits nine Dremel models plus the 4300 with a collet and collet nut. We have not used this kit ourselves; the review is based on the manufacturer’s listing on Amazon, collected 19 October 2026, and what its specs mean for firewood work.

Dremel A679-02 Sharpening Attachment Kit
A sharpening attachment kit that screws onto Dremel rotary tools, with three sharpening attachments and four grinding stones for garden tools and chainsaw chains.
Pros
- Three attachments: garden tool, lawn mower and chain saw sharpening
- 453, 454 and 455 aluminum oxide stones for 1/4, 3/8 and .325 in chains
- Fits nine Dremel models plus the 4300 with a collet and collet nut
- Gauge, two spacers and wrench included in the kit
Cons
- No warranty term stated; the spec table answers No
- Rotary tool not included; the kit alone sharpens nothing
- Only four chain sizes stated: 1/4, 3/8, 3/8 low profile and .325 in
- Spec table says Number of Items 1 though the bullets describe a multi-piece kit
Dremel A679-02 review: the short verdict
A dull chain makes every cut slower and hotter, and hand filing is slow work. The A679-02 answers that by giving a rotary tool three guided attachments: one for garden tools, one for lawn mower blades and one for chain saws, plus aluminum oxide stones sized for 1/4 inch, 3/8 inch, 3/8 inch low profile and .325 inch chains. The attachments screw onto the rotary tool, and the listing credits them with the optimum sharpening angles.
For firewood, the chain saw attachment is the one that matters. A sharp chain throws chips instead of dust and cuts faster and cooler, and keeps the saw out of the dirt-dragging death spiral; this kit is for the cutter who already owns a compatible Dremel and wants guided sharpening without buying a dedicated bench grinder. The weak spots are on the paperwork side: the spec table answers “No” to the warranty question, and the rotary tool itself is not in the box.

Specifications are manufacturer rated, as published on the Amazon listing. The bullets describe a kit with three attachments, four stones, a wrench, a gauge and two spacers, while the spec table says “Number of Items: 1”; trust the bullets, it is a multi-piece kit. The spec table also answers the warranty question with a flat “No,” so no warranty term is stated. The spec table lists 2.95 kg; the listing does not say what that covers, so do not read it as the weight of a single attachment.
The kit
What the A679-02 does well
Three attachments in one kit
The kit covers the three edges a property owner sharpens most: garden tools, mower blades and chainsaw chains. Each attachment screws onto the Dremel rotary tool, and the listing describes installation as simple. Buying the three guides together beats hunting them down one at a time, and the included wrench, gauge and two spacers mean the kit is complete on arrival, apart from the rotary tool itself.
Stones matched to common chain sizes
The 453, 454 and 455 aluminum oxide stones are stated for 1/4 inch, 3/8 inch, 3/8 inch low profile and .325 inch chains, the four pitches the listing names for these stones. The fourth stone, the 932, is listed among the grinding stones without a stated chain size. The three chain stones are aluminum oxide, per the listing, which frames the set as the popular choice for the dullest chains and blades.
Wide Dremel compatibility
The kit fits Dremel models 100, 200, 3000, 4000, 7760, 8220, 8240, 8250 and 8260, and it fits the Dremel 4300 when used with a collet and collet nut. That is ten tools across the Dremel line; check the list against the model you own. The kit includes a gauge for setting the sharpening angle; the attachments themselves provide the angles the listing calls optimum.
Guided angles for garden tools too
The garden tool and lawn mower attachments extend the kit past the woodpile: each attachment holds its guide angle so the edge stays consistent, which is the hard part of sharpening freehand. For a property owner who already maintains all three, one kit and one rotary tool covers the sharpening bench.
Limitations
- No warranty stated. The spec table answers the warranty question with “No.” If the term matters to you, ask the seller before buying.
- Rotary tool not included. The kit is attachments and stones only; you need a compatible Dremel already, from the nine listed models or the 4300 with a collet.
- Four chain sizes only. The stones are stated for 1/4 inch, 3/8 inch, 3/8 inch low profile and .325 inch chains. Other pitches are not covered by the listing.
- Thin spec table. Stone grit, attachment materials and the gauge’s angle settings are not stated. The “Number of Items: 1” row contradicts the multi-piece kit the bullets describe.
- Handheld sharpening still takes practice. The guides set the angle, but a steady hand and light passes are still on you; rushing with a rotary stone can overheat a tooth.
How we scored it
The Woodlot Score weighs performance, build, value, safety and warranty, using only what the listing publishes. The kit scores on the breadth of the kit and the stated chain sizes, and loses warranty points because the spec table answers “No.”
| Product | Woodlot Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Dremel A679-02 | 9.6 | 28 | 20 | 20 | n/a | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.
Who should buy the Dremel A679-02, and who should skip it
Buy it if
- You already own a compatible Dremel rotary tool, one of the nine listed models or the 4300 with a collet.
- You cut firewood with 1/4 inch, 3/8 inch or .325 inch chain and want guided touch-ups between filings.
- You also sharpen mower blades and garden tools and want one kit for all three.
- You prefer a small kit that stores in a drawer over a dedicated bench sharpener.
Skip it if
- You do not own a Dremel; the kit alone sharpens nothing.
- Your chain is a pitch the stones do not cover; check the 1/4, 3/8 and .325 inch list first.
- You want a written warranty term before you buy and the seller cannot confirm one.
- You sharpen chains daily at volume; a dedicated grinder suits a production pace better.
Alternatives to consider
Standalone sharpeners. Our best chainsaw sharpener roundup covers file kits and grinders that work without a rotary tool, for cutters who do not own a Dremel.
File guides. For the purist, a manual file with a guide, like the ones in our electric sharpener vs file comparison, needs no power and no collet, at the cost of speed.
Safety and gear
Wear eye protection and gloves for cutting, splitting and handling, follow every tool's manual, install stoves to code, and have the chimney inspected and cleaned every year. See EPA Burn Wise and NFPA heating safety. Read our Safety Disclaimer.
Grinding throws sparks and grit: wear eye protection and gloves when you sharpen, clamp the workpiece so it cannot move, and let the stone do the work with light passes. Keep fingers clear of the spinning stone, unplug or switch off the rotary tool when changing attachments, and work away from fuel and sawdust. This site does not give felling instructions; for felling, hire a qualified arborist.
Around the Woodpile
- The attachments screw onto the rotary tool, so the kit packs down to the attachments, stones, gauge, spacers and wrench in a drawer.
- Keep the gauge with the kit; the attachments provide the sharpening angles the listing calls optimum.
- The 453, 454 and 455 stones are the chainsaw stones; the 932 is listed as a grinding stone without a stated chain size.
- Store stones dry and apart so they do not chip each other between sharpening sessions.
