Choosing the Right Grout Removal Bit Size
Choose a bit that is slightly narrower than the grout joint. If you are uncertain, begin with the smaller size. You can widen the joint gradually, but starting with a bit that is too large increases the chance of touching the tile edges.
| Bit Size | Best Use | Removal Style |
|---|---|---|
| 1/16" | Narrow grout lines, detail work, and careful cleanup | Precise |
| 3/32" | Common grout joints and general-purpose grout removal | Balanced |
| 1/8" | Wider grout joints and heavier grout removal | Faster |

Why Use Solid Carbide for Grout Removal?
Grout and mortar residue are abrasive materials. Solid carbide offers better wear resistance than softer steel tools and helps the bit remain effective longer during grout-removal work.
- Good wear resistance in abrasive grout and cement-based materials
- Controlled cutting in narrow tile joints
- Useful for repair work where only selected areas of grout need to be removed
- Standard 1/8" shank fits many Dremel® and similar rotary tools
- Made in USA

How to Remove Tile Grout with a Rotary Tool
- Choose a bit slightly narrower than the grout joint.
- Begin at a moderate rotary-tool speed.
- Use light pressure and allow the carbide bit to do the cutting.
- Make a shallow first pass, then deepen the cut gradually.
- Keep the tool moving to reduce heat buildup.
- Take extra care near tile edges.
- Vacuum dust frequently so the grout line remains visible.
- Use a compatible cutting guide when possible for improved 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. Hearing protection and suitable gloves are also recommended when operating a rotary tool.
Work in a well-ventilated area, control dust with a suitable vacuum, and follow all safety instructions provided with your rotary tool and guide. Grout, mortar, cement board, ceramic tile, porcelain, and related materials may contain or release fine silica-containing dust when cut, ground, or abraded.
