A Core deposit is a form of deposit you pay until returning your old part. If you don't have the core at the time of purchase, you must pay the core charge. That charge is refunded to you when you return the core.
A new bar has been set for metal cut-off wheels with the MetalMax series from Lenox. Their advanced diamond technology provides extreme durability allowing 1,000 or more cuts with no need for wheel changes while maintaining speed and finish. The cutting depth remains the same throughout the life of the wheel thanks to its diamond edge coated steel body construction. Lenox's MetalMax cut-off wheels are recommended for multiple types of metal including steel, sheet metal, stainless steel, rebar, cast iron, aluminum and non-ferrous metals.
