Match three things and you cannot go far wrong: the rim type to the material, the diameter to the machine, and the RPM rating to the spindle speed. The tables below cover all twelve TUSKO series with the diameter range and arbor each one is made in.
| Material / application | Series | Diameter | Arbor |
|---|---|---|---|
| Concrete, paving slabs, brickwork | TS segmented | 115-350 mm | 22.2 / 25.4 mm |
| Reinforced concrete, hard aggregate | TSO ordered (laser welded) | 115-350 mm | 22.2 / 25.4 mm |
| Granite, engineered stone, cured concrete | TT turbo | 115-230 mm | 22.2 mm |
| Porcelain, ceramic tile, chip-free cuts | TN continuous | 105-230 mm | 20 / 22.2 mm |
| Marble, travertine, natural stone | TC continuous for stone | 110-230 mm | 20 / 22.2 mm |
| Roads, asphalt, wall sawing | TR large diameter | 350-800 mm | 25.4 / 60 mm |
| Kerb stones, roofing tiles, green concrete | TSB brazing | 115-230 mm | 22.2 mm |
| Angle grinder, fast dry cutting | TSF mesh turbo | 115-125 mm | 22.2 mm |
| Floor coating removal, concrete grinding | TG grinding plate | 100-180 mm | 22.2 mm |
| Core drilling, reinforced concrete | CD core drill | 8-1000 mm | threaded / hex |
| Deep holes, replaceable cutter head | Threaded tube | 26-300 mm | threaded |
| Granite, marble, tile drilling | Stone hole saw | 6-165 mm | triangular shank |
Diameter and arbor figures are the standard production range of each series; other sizes are made to order.
Rim speed is what actually limits a blade, not diameter on its own. The table converts a 60 m/s working rim speed and an 80 m/s maximum into spindle RPM for each common diameter, so you can check a blade against any machine.
| Blade diameter | RPM at 60 m/s | RPM at 80 m/s | Typical machine |
|---|---|---|---|
| 100 mm | 11,459 | 15,279 | Angle grinder |
| 115 mm | 9,964 | 13,286 | Angle grinder |
| 125 mm | 9,167 | 12,223 | Angle grinder |
| 150 mm | 7,639 | 10,186 | Large angle grinder |
| 180 mm | 6,366 | 8,488 | Large angle grinder |
| 230 mm | 4,982 | 6,643 | Large angle grinder |
| 300 mm | 3,820 | 5,093 | Cut-off saw |
| 350 mm | 3,274 | 4,365 | Cut-off saw |
| 400 mm | 2,865 | 3,820 | Floor saw |
| 450 mm | 2,546 | 3,395 | Floor saw |
| 500 mm | 2,292 | 3,056 | Floor saw |
| 600 mm | 1,910 | 2,546 | Wall saw |
| 800 mm | 1,432 | 1,910 | Wall saw |
Calculated with RPM = rim speed × 60,000 ÷ (π × diameter). Always use the lower of the two numbers when the blade label states a maximum RPM.
Deep gullets clear slurry and debris, so the blade stays cool and cuts fast. Best in concrete, brick and asphalt where finish does not matter.
A serrated continuous edge: faster than a continuous rim, cleaner than a segmented one. The general-purpose choice for granite and hard concrete.
No gullets, so the edge stays intact and the cut is chip-free. The only correct choice for porcelain and polished stone, and it needs water.
Use a segmented rim for cured concrete, paving slabs and general building work where fast cutting matters more than a clean edge. For reinforced concrete, switch to a laser-welded ordered rim, which holds the diamond in the matrix when it meets rebar. Continuous rims are the wrong choice here: they cut slowly and overheat.
It is the highest spindle speed the blade is rated for, set by the rim speed the bond can survive. A 115 mm blade rated for 13,000 rpm is safe on a standard 11,000 rpm angle grinder; a 350 mm blade rated for 4,300 rpm must never go on a machine running faster. Always check the blade label against the machine's no-load speed.
22.2 mm is the standard bore for 100-230 mm angle grinder blades worldwide. Large blades use 25.4 mm or a 60 mm drive hole for floor saws and wall saws, while core drills use a threaded or hex drive depending on the rig. If your machine uses a different spindle, a reducing ring solves it.
Segmented rims have deep gullets that clear debris fast, so they cut quickly in abrasive material. Turbo rims have a serrated continuous edge that cuts fast but leaves a cleaner finish. Continuous rims have no gullets at all, which gives a chip-free edge in tile, porcelain and marble but limits speed and requires water.
Almost always glazing: the diamond segments polish over because the blade is cutting soft abrasive material at too low a pressure, or running without enough water. Cut a few passes through an abrasive block or hard concrete to expose fresh diamond, then reduce spindle speed and check water flow.
