This is a set from old stock. I can’t say that it hasn’t been used because it has been opened and there is some gunk on it, but there is no telling how many places it’s been over the years, so that could be why. If it has been used it was used very lightly!!!The Central Pneumatic Air Hammer #4842 is a pistol grip air tool that comes in a set with a bit set included. It has a keyless chuck key type and operates at a maximum speed of 4500 BPM. The unit is designed for use with a 1/4 inch air inlet size and is suitable for various automotive and industrial applications. The product is in excellent condition and will be shipped quickly to the buyer.
