Hardell Rotary Tool Accessory Sets: How to Use the 508-Piece and 287-Piece Kits
Half of what makes a rotary tool useful is the bit collection. Hardell stocks two large in-stock accessory sets: the 508-piece set (A41-TYRTPJ508-1) and the 287-piece set (A41-TYRTPJ225-1). Both cover grinding bits, cut-off wheels, polishing wheels, drill bits, and collets that fit every Hardell rotary tool—cordless 4V/12V and corded 180W/200W alike.
How to Get the Most from Your Accessory Set (HowTo)
1. Sort and store by type
Group bits into small boxes: diamond/carbide grinding bits (carving), sanding drums (shaping), cut-off wheels (slicing), and felt/bristle wheels (polishing). A sorted kit saves more time than a bigger kit that is a jumble.

2. Pick the right collet
Standard 3.2 mm (1/8 inch) shank bits drop straight into the Hardell collet. For thinner shanks, use the 3-jaw adapter so the bit runs true and does not wobble.

3. Choose by the job
- Wood carving: ball or cylinder diamond/carbide bits.
- Metal deburring: ceramic grinding bits.
- Cutting: resin cut-off wheels at a low speed.
- Polishing: cotton wheel with polishing compound.

508-Piece vs 287-Piece
| Set (SKU) | Pieces | Best for |
|---|---|---|
| A41-TYRTPJ508-1 | 508 pieces | All-scenario, heavy users |
| A41-TYRTPJ225-1 | 287 pieces | Regular home use, best value |
If you already own one of the 42/69/80/129-piece rotary kits, the 287-piece set tops it up nicely. If you want one box to cover every project for months, the 508-piece set is the full solution.
Frequently Asked Questions
Will these bits fit my 4V Hardell tool?
Yes. Every Hardell rotary tool uses the 3.2 mm standard shank, so the 508 and 287-piece sets work across the whole lineup.
Which set should a beginner buy?
The 287-piece set (A41-TYRTPJ225-1) covers typical home tasks at a lower cost. Move up to the 508-piece set only if you use many different materials.
Do I need the collet adapter?
Only for non-standard thin shanks. Most bits in the set use the standard shank and fit directly.
Final Verdict
Pair the in-stock 508 or 287-piece Hardell accessory set with any Hardell rotary tool to cover grinding, cutting, drilling, and polishing. Sort by type, match the collet, and pick bits by material—that is the whole system.
