Resin Bond Diamond Wheels for Woodworking Tools
- Cool cutting on TCT saw, router, and cutterhead grinders
- Fine finish on carbide teeth, flutes, and knife faces
- Diamond abrasive for carbide-tipped woodworking tools — not for steel
- Made to your diameter, grit, and concentration
Product Information
Overview
Resin bond diamond wheels grind carbide-tipped woodworking tools — TCT saws, router bits, cutterheads, and planer knives. The bond self-sharpens, keeps heat low, and holds a sharp edge.
Typical saw grinders: Vollmer, Woodtronic, Akemat, Widma. Cutterheads and knives: Weinig, Stehle, and equivalent CNC grinders. Diamond resin is for carbide tips; HSS or steel knives need CBN.
Typical Workpieces
| Workpiece | Common operations |
|---|---|
| TCT circular saw blades | Face, top, and flank grinding; hollow tooth if required |
| Carbide router bits | Flute, clearance, profile |
| Finger-joint & helical cutterheads | Face, periphery, clearance |
| Carbide planer / jointer knives | Face and cutting edge |
| Spiral / insert cutterheads | Insert edges and seats |
| Profiling / shaper cutters | Profile and clearance |
Shapes
| Shape | Drawing | Role on woodworking tools |
|---|---|---|
| 4A2 |  |
Face grinding of TCT teeth — the most requested cup on saw grinders |
| 12V9 |  |
Face grinding in tight tooth gaps; also router-bit flutes |
| 11V9 |  |
Flute grinding on spiral bits and woodworking cutters |
| 6A2 |  |
Top grinding of saw teeth; face / cup on cutterheads and knives |
Also available: 1A1 (OD and cylindrical grinding of cutter bodies), 14V1 (gullet and root cleaning), 1V1 (narrow slots and clearances), 3A1.
Common grit for carbide saw teeth: D46–D91. Send your current wheel mark (e.g. 4A2-125-2-20 D64 C75) or a drawing. We match diameter, thickness, hole, grit, and concentration to your machine and coolant.
When not to use resin bond
- Grinding or sanding wood itself → these wheels grind the tools, not the timber
- HSS or steel planer / jointer knives → CBN, not diamond
- Maximum wheel life with heavy wet grinding of brittle materials → metal bond
- High-volume PCD woodworking tools with dressing on a production line → vitrified diamond
- Cutting glass, quartz, or LED substrates → metal or electroplated cut-off wheels (1A1R)
