Choosing the Right Grout Removal Bit Size
The best size depends on the width of your grout joint and how much material you need to remove. If you are unsure, start smaller. You can always widen the joint with a larger bit, but starting too large can increase the risk of touching the tile edge.
| Bit Size | Best Use | Removal Speed |
|---|---|---|
| 1/16" | Narrow grout lines, detail work, controlled cleanup | Fine / slower |
| 3/32" | Common grout joints and general-purpose grout removal | Medium |
| 1/8" | Wider grout joints and heavier removal | More aggressive |
Why Use Solid Carbide for Grout?
Grout and mortar residue are abrasive materials. Solid carbide offers better wear resistance than softer steel tools and helps the bit stay effective longer during grout removal.
- Good wear resistance in abrasive grout and cement-based materials
- Controlled cutting in narrow tile joints
- Useful for repair work where only selected grout areas need to be removed
- 1/8" shank fits many Dremel® and rotary tools

Tips for Removing Tile Grout with a Rotary Tool
- Use light pressure and let the bit do the cutting.
- Start with a shallow pass, then deepen gradually.
- Keep the tool moving to reduce heat and avoid chipping tile edges.
- Vacuum dust as you work so you can see the grout line clearly.
- Use a guide attachment when possible for better control.
Safety and Dust Precautions
Grout removal can create dust and flying particles. Always wear appropriate personal protective equipment, including safety glasses or goggles and a dust mask or respirator suitable for fine dust. Gloves and hearing protection are also recommended when using rotary tools.
Work in a well-ventilated area, vacuum dust frequently, and follow the safety instructions for your rotary tool and any guide attachment. Grout, mortar, cement board, ceramic tile, porcelain, and similar materials may contain or release fine silica-containing dust when cut, ground, or abraded.
Frequently Asked Questions
What size grout removal bit should I use?
Choose a bit size based on the width of your grout joint. For narrow grout lines or careful detail work, use 1/16". For many common grout joints, 3/32" is a good middle size. For wider joints or faster removal, use 1/8". If you are unsure, start smaller and widen the joint gradually.
Can these bits cut tile?
No. These bits are intended for removing grout between tiles. They are not designed for drilling holes through tile or cutting large areas of ceramic, porcelain, or stone tile.
Will these fit a Dremel tool?
Yes. These grout removal bits have a standard 1/8" shank, which fits Dremel® and similar rotary tools that accept 1/8" shank accessories.
Are these sold as a set?
No. Each quantity equals one (1) grout removal bit. Choose the size you want from the product options. You can mix 1/16", 3/32", and 1/8" sizes in the same order, and quantity discounts apply to the total number of bits.
Can I use these with a rotary tool guide?
Yes. These bits can be used with compatible rotary-tool guides such as the Dremel 565 and Dremel 566 cutting guides. They are not compatible with the Dremel 568-01 grout removal depth-setting attachment.
Important: These Are for Grout Removal, Not Tile Drilling
These bits are designed for removing grout between tiles. They are not intended for drilling holes through tile or for cutting large areas of ceramic, porcelain, or stone tile.
For best results, choose a bit size that is slightly smaller than the grout joint and work gradually.
