Hey race fans, how important are tires to the whole equation? It’s hard to hook up without good tires. We’ve all experienced times where we wish our tires were transferring a little more of the engine’s power to the road. But what about your power tool? What about the interface between the tool and the accessory – that’s power transfer, too. It matters whether your blade fits tight in you multi-tool or whether your three jaw chuck is grabbing that twist drill bit. Pay attention to how well your bit fits in the chuck. SDS Plus, SDS Max, T Shank and OIS are all Bosch designations for interfaces – basically power transmission connectors. The next time you pick up a power tool, think about the interface. Is it the best?
