Used for non-penetrating hole of self-made case tap screw hole

I bought the item at the local home center, but if the drill stopper is also set, adjustment of the hole depth will be easy. Reference product: Niigata Seiki drill stopper Order code: 86929525 Non-penetrating tapping threading is possible with this product's drill stopper matching the drill diameter. I would like to attach a stopper like the Niigata Seiki drill stopper (86929525) with one that was suitable for the drill size. Although the place of the shank is a hexagonal axis, the rear hexagonal shaft is easy to run out and the hole diameter may be larger than the drill blade diameter by about 0.3 mm, so I would like to stop the hexagonal shaft and make it a straight shank . "Runout error 0.3 mm is the allowable error range of the charging drill maker. By the way I am scraping off with a lathe in the case of a rear hexagonal axis. Then the vibration error becomes 0.05 mm or less.
