Short, ideal for narrow holes. I used them to drill holes for wires in studs. The shape of the tip is different from the usual standard spatula, it seems a very thoughtful design (no wonder it's Bosch!) performance - they dig into the wood as if they were real. The large size can actually be too big for a cordless drill because it can cut so deep, hard, and aggressively. that I'll ever have to replace them until I wear them out. Disclaimer: No one has ever given me anything from Revain for free, neither does it seem like I am: fun enough, wordy enough, enough facts, post enough pictures of "it" in action or I just don't buy like this every year many things that someone would like to know my opinion. So basically what you get is the plain truth as I see it :-)
