Exquisite Ultra-Hard Storage BoxAll taps and drill bits are stored in an orderly manner in this exquisite ultra-hard Indexed storage box, which is very convenient for accessing and storing tap tools and convenient for carrying around. NoteThe drill bit is very sharp and is tightly fixed to the drill bit holder. Please wear gloves or use tools to remove it from the holder.
Warm TipsDrill holes with a twist drill bit first, then tap with a thread tap. Tapping and drilling angle should be 90 degrees vertical and stable. The higher the hardness, the slower the speed. The tapping depth should not exceed 1.5 times the diameter of the tap (For example, the diameter M6x1 is about 6mm, and the depth should not exceed 9mm. )
