Explain Bit Replacement in 4-in-1 Tool

unlock the collar ah insert and flip the the the insert so the unique part about this is not that we can you know um you know do a counter syn or drill a hole but you can flip it over and then have a drill bit right there so you're not searching for another bit right so very convenient right does the bit come out yeah that's a good point so this is designed with a hex key in the shank right and you uh use that to remove or loosen the set screws oh to change the bit you change the bit that's pretty cool feature right there you also do the same thing for the counter SN or to replace the drill bit the counter sink so if you break the drill bit or the Dr bit wears out you can replace correct the drill bit well that's kind of nice that's pretty handy little tool I like
