How to choose the best cut off wheel for die grinder
Match the wheel to the grinder
Check diameter and arbor: the 3 in wheels here use a 3/8 in arbor with a 1/4 in mandrel, the 2 in SI FANG fits small die grinders, and the 4 in BHA reaches where a full-size grinder cannot. The best cordless die grinder for exhaust work pairs well with the 3 in packs.
Read the RPM rating
The wheel’s max RPM must clear the grinder’s speed: 30,000 RPM on the 2 in SI FANG, 25,000 RPM on the SI FANG 3 in, 20,380 RPM on the SALI and 20,000 RPM on the PRETEC. A wheel rated below the tool’s speed is a safety risk, not a bargain.
Count the pack and the kit
Wheels wear fast, so pack size is value: 55 with the PRETEC, 50 with the SALI, 25 with the BHA and SI FANG 3 in, 11 with the 2 in SI FANG. The PRETEC and both SI FANG packs include a mandrel, and the SI FANG 3 in adds a pouch. For smaller rotary work, see the best small cut off wheel.
Wear eye protection with every air tool, use impact-rated sockets on impact wrenches, disconnect the air line before changing accessories, and finish lug nuts with a torque wrench to the vehicle's spec. See OSHA eye and face protection. Read our Safety Disclaimer.
Garage Fit Check
- Arbor: 3/8 in arbor with a 1/4 in mandrel for die grinders (PRETEC, SI FANG).

- Eye protection: the SI FANG 3 in listing requires eye protection or a face shield.
- Storage: the SI FANG 3 in kit includes a carrying pouch for the wheels and mandrel.
- Cutting material: all five cut steel and stainless steel; check the listing for exotic metals.
