I went to harbor freight to pick up a grinder with a composite body, im getting tired of my hand freezing off while im porting these 289 heads. i found a composite bodied 1/4" for $8 but I wont be back at the shop to try it till tomorrow. They also had the Central Pnumatic Professional for $15. The safety on the red one has a horrible design, but it was super easy to pop off.
