Super Mario World
Grinders appeared in Super Mario World as enemies found in castles. Mario or Luigi can spin jump on them. Some Grinders are line-guided, and others are not. The line-guided Grinders follow a certain path, while the non-line-guided can go left or right.
After a long disappearance, Grinders return in Super Mario Galaxy 2 as obstacles in the Puzzle Plank Galaxy and the Rolling Masterpiece Galaxy, where they cut through wood planks, causing them to fall. When Mario comes near a Grinder, it starts moving and can defeat any enemy that touches it.
Grinders reappear in Super Mario 3D Land, but they are only found on World 7-5 as the main obstacles for the level.
Grinders appear again in Paper Mario: Sticker Star as obstacles only found in Chomp Ruins. Is Mario touches one of the Grinders, he will get hurt.
A Grinder appears in Super Smash Bros. for Nintendo 3DS and Wii U as Bowser Jr.'s dash attack.
Grinders reappear once again in Super Mario Maker and it's Nintendo 3DS release as obstacles. They had to make sprites for Grinders for the Super Mario Bros. and Super Mario Bros. 3 styles because they didn't appear in those games. New sprites for Grinders were made for the Super Mario World style and the New Super Mario Bros. 2 Grinder sprites from that game were reused in the New Super Mario Bros. U style. Non-line-guided Grinders now stay in the air.
Grinders appeared in Mario & Luigi: Paper Jam as obstacles in the Trio Drill sections of Mount Brrr. If one member of the trio touches a Grinder, they will be forced out of the dirt.
