Electroplated Diamond Cut-off Wheels
- Single-layer diamond rim — sharp on the first cut
- Thin 1A1R for glass, fused quartz, LED, and ceramic blanks
- Tight kerf; replace the wheel when the rim is dull
- Made to your diameter, thickness, and hole
Product Information
Overview
Electroplated wheels for thin cut-off of glass, fused quartz, LED blanks, and technical ceramics. Single-layer diamond on a steel core. Wet cut-off is standard.
- Sharp on the first cut — low cutting force, less chip-out on glass and quartz
- Thin rim; thickness is the kerf
- No dressing — replace the wheel when the rim is dull
- Short and medium runs
Applications:
- Glass tube, rod, and sheet cut-off (not straight-line edge grinding)
- Fused quartz tube, plate, and rod
- LED wafers, sapphire, and similar hard blanks
- Technical ceramic bar and plate
Architectural glass edge, arris, and OG stay on metal bond × glass. Silicon wafer production cut-off with life as the first spec stays on metal bond × silicon wafers.
Kerf
Order thickness for the cut you need, not as thin as possible. Glass tube often wants a different T from quartz plate or an LED blank. Wet unless the machine is already dry. Runout on a 0.6 mm rim matters more than a polished side wall.
Metal 1A1R on the same saw is the long-life rim. Keep it if the blade already lasts the shift. Use plated 1A1R when you need a sharper first cut, a thinner T than the metal rim you have, or a diameter and hole the metal tool is not tooled for.
Shapes
| Shape | Drawing | Role |
|---|---|---|
| 1A1R |  |
Thin wet cut-off. Core + plated diamond rim. Kerf follows rim thickness |
| 1V1 |  |
Narrow groove or a bevelled cut when the stamp is already 1V1 |
Send a mark such as 1A1R-125-0.6-22 plus material (glass / quartz / LED / ceramic), wet/dry, and kerf if you already run a number. We match diameter, thickness, hole, and grit.
When electroplated cut-off is the wrong wheel
- Architectural glass edge, arris, OG → metal × glass
- Long-life quartz or wafer cut-off → metal 1A1R
- Carbide flutes or saw teeth → resin
- Hardened steel OD → vitrified CBN
- Internal and jig grinding → electroplated jig / internal
