Model EDP Heavy-Duty Valve Seat Grinder

The Hall-Toledo Model EDP Eccentric Valve Seat Grinders are designed to get heavy-duty diesel, gas, and gasoline engines back in service fast.

They are used worldwide to maintain locomotive, marine, natural gas, and stationary engines and have been recommended by major engine manufacturers. With a valve seat range of 1" - 7" (25 mm – 178 mm), the Model EDP "point-contact" grinders enable all operators to quickly grind valve seats of all materials to better than original OEM specifications with minimum removal of stock.
