Dremel 729-01 11-Piece Carving & Engraving Rotary Tool Accessories Kit - Includes Engraving Bits & Grinding Stones- Ideal for Wood, Metal, and Glass

Overview

Good accessory kits don’t try to do everything; they give you the right handful of tools that actually get used. That’s the story with this Dremel carving and engraving kit. It’s a compact, focused set built around three families of bits—high‑speed steel engraving cutters, diamond wheel points, and silicon carbide grinding stones—packed in a small reusable case. I’ve been using it on a mix of wood, metal, and glass projects over the past few weeks, and it’s quickly become the kit I grab when I need to mark, shape, or finesse small details with a rotary tool.

What’s in the kit

The 729-01 kit includes 11 accessories sized for fine work:

• Four high‑speed steel engraving cutters in small diameters for line work and small relief carving.
• Two diamond wheel points (both 5/64") for etching and detail work on glass, stone, tile, and hardened steels.
• Five green silicon carbide grinding stones in useful profiles and diameters for sharpening, deburring, and light shaping of non‑ferrous metals, glass, ceramics, and plastics.

All pieces use 1/8" shanks, so they drop straight into a standard Dremel collet or keyless chuck.

The case is a compact gray clamshell with a clear lid. It actually holds the bits securely (not a given with small accessory cases), and it’s thin enough to live in a tool bag without hogging space.

Setup and compatibility

I ran these in a Dremel variable‑speed rotary tool with a 1/8" collet and also in a third‑party flex‑shaft. No adapters needed. As always with small bits, runout matters: if your collet is worn or you’re using a cheap chuck, you’ll feel chatter. A quick wipe of the shank and a snug collet torque kept everything running true.

Speed-wise, I stayed in the 8,000–25,000 RPM range for most tasks:
- Wood and plastics: 15,000–25,000 RPM
- Soft metals (aluminum, brass): 10,000–20,000 RPM
- Glass and tile with diamond points: 5,000–15,000 RPM, with light water mist to keep dust down and the bit cool

Performance on different materials

Wood

For fine carving and lettering in basswood and maple, the small engraving cutters are the stars. The 1/32" cutter behaves like a mechanical pencil for line work, and the slightly larger profiles make short work of widening and shaping strokes. They cut cleanly at higher RPMs and leave crisp edges in tight radii, especially if you keep a light hand and let the speed do the work. On hardwoods, I found that two or three shallow passes beat one deep plunge—control is better, and tear‑out is minimal. A quick pass with a sanding sponge afterward is usually all you need.

Metal

The green silicon carbide stones are very handy for deburring and bringing stubborn fastener ends flush. I used the 3/16" and 1/8" stones to flatten a sheared steel screw below the surface of a countersink, and they held their shape well enough to keep the surrounding workpiece untouched. Silicon carbide isn’t the most durable choice on ferrous steel compared to aluminum oxide, but in these small diameters it’s perfectly serviceable and cuts cool.

For brass and aluminum fittings, the stones shine: they remove burrs without grabbing and they’re less prone to loading than the steel cutters. If you do load them up, a quick touch to a dressing brick or a rub with a gummy abrasive cleaner brings them back.

I wouldn’t use the steel engraving cutters for heavy metal removal—use the stones or the diamond points instead. The cutters will gum on soft metals if you push too hard; a little wax or light oil helps, but these really belong in wood and plastic.

Glass, tile, and stone

The diamond wheel points cut neat, controllable lines in glassware for simple monograms and marking. They’re small, so they’re better for etching and signing than for hogging out material. Work at lower speeds, barely any pressure, and keep the area damp. On a ceramic tile, the diamond points let me break the glaze where I planned to drill, which helps keep a tile bit from walking. They also do clean‑up and small relief work on agate and stone without the “chatter” you get from non‑diamond bits.

Plastics

Acrylic and ABS respond nicely to the steel engraving cutters if you keep your feed rate up and your speed moderate. Too slow and you’ll melt edges; too fast and you’ll chatter. The small diameters in the kit make it easy to chase tight corners without leaving scoops.

Control and feel

Control comes down to bit geometry and feedback. The small size of these tips encourages a light touch, and that’s a good thing. The engraving cutters give a “skating” feel when you’re at the right speed—consistent chips, no chatter. The diamond points “hiss” and track predictably in glass. The silicon carbide stones feel smoother than aluminum oxide; they’re less grabby on edges, which is a plus for touch‑up work.

Using a flex‑shaft makes a huge difference in comfort. With the motor off your hand, the kit turns your rotary tool into a pen for detail work. I highly recommend it if you’re doing long sessions of engraving.

Durability and wear

After several sessions, here’s how wear shook out:
- The steel engraving cutters stayed sharp in wood and plastics. They’ll dull quickly if you try to plow through steel; keep them in softer materials and they last.
- The diamond points held up well with light pressure and water on glass and tile. They’re small, so don’t expect them to remove bulk—use them for etching and precision.
- The silicon carbide stones wear predictably and can glaze if you run them hot on steel. Dress them periodically to refresh the abrasive.

Nothing chipped prematurely, and shanks stayed straight. The kit feels like standard Dremel quality throughout.

Case and organization

The case is genuinely useful. The inserts grip the bits, the lid is clear, and it’s slim enough for a drawer or bag. My only gripe: the factory seal on the case left some adhesive on the lid when I first opened it. Not a performance issue, just a little cleanup with mineral spirits. Otherwise, the case has kept the bits sorted and easy to grab.

What could be better

• Breadth vs. depth: You get two diamond profiles. I’d love one more (a small ball or needle) to round out glass and ceramic work.
• No aluminum oxide stones: The included silicon carbide lineup is great on non‑ferrous metals and glass, but if you plan to grind a lot of steel, an aluminum oxide stone will outlast and run cooler.
• No cleaning stick or dressing stone: A tiny abrasive eraser or dressing brick would make this a more complete sharpening/grinding micro‑kit.

None of these are deal‑breakers given the kit’s focus and price, but they’re worth noting depending on your workflow.

Who it’s for

• Hobby woodcarvers and model builders who need fine engraving cutters for crisp lines.
• DIYers who occasionally etch glass, mark tile, or touch up a chipped edge.
• Metalworkers who want small stones for deburring and flush‑trimming fasteners in tight spots.
• Anyone with a Dremel who wants a compact, go‑to selection of detail bits that actually get used.

If you’re looking for heavy stock removal or a full finishing suite (sanding drums, polishing wheels), this isn’t that. It’s a precision kit for carving, etching, and small‑scale grinding.

Tips for best results

• Use the engraving cutters in wood and plastics at higher RPMs with feather‑light passes. Let speed, not pressure, do the work.
• On glass and tile, run the diamond points slow, add a drop of water, and keep your strokes short to control heat.
• For metal deburring, start with the silicon carbide stones, not the steel cutters. Dress the stones occasionally to keep them cutting.
• Keep a brass brush or rubber abrasive stick handy to clean loaded bits.
• Consider a flex‑shaft for comfort and control on detail work.
• Always wear eye protection; small bits can shatter if misused, and glass/tile dust deserves respect.

Recommendation

I recommend the 729-01 kit for anyone who needs a compact, capable set of carving and engraving accessories for a rotary tool. It earns a spot in the drawer because it covers the essentials—fine cutters for wood and plastics, diamond tips for hard materials, and a practical mix of stones for sharpening and deburring—without fluff. The bits cut cleanly, the diamond points etch predictably, and the stones are the right sizes for real‑world fixes in tight spaces.

It’s not an all‑in‑one finishing solution, and if your work skews heavily toward grinding ferrous steel, you’ll want to add an aluminum oxide stone or two. But as a focused, everyday detail kit with reliable quality and a genuinely useful case, it’s an easy yes.
