This drill is to be used to review crowns, rims, etc.. of the brands in which the axles are 2.38mm. they cost to enter or they simply don’t enter and so being able to adjust the orifice to this measure, it can also be used to create this measure, 2.38mm.
NOTE.:
It is important to know that when it comes to reaming the hole in a crown or a rim, it is best to do it manually, either by taking the drill bit directly by hand and reaming the hole until the shaft enters the part to be chosen or with a manual drill, never with a mini drill or electric drill as the excess revolutions and vibration can make the hole too large.
