?Recommended for DIYers◎

?Solves the hassle and difficulty of collecting spiral bits.

?No need to switch bits with a step drill (bamboo shoot drill).

?No more tedious bit changes.

?How to Use

?First, mark the material you want to drill, such as wood, stainless steel, plastic (like vinyl chloride pipes), or sheet metal (like iron pipes).

?Since a step drill cuts as it drills, you can prevent mistakes by slowly drilling while checking the hole size. However, to avoid making the hole too large, mark the surface with masking tape or similar.

?Once marked, attach the step drill to your drill driver.

?When attaching, make sure it is centered properly.

?You can check if it's centered by running the drill briefly without load.

?Once correctly attached, drill the hole in the material.

?If you are using a step drill that is larger than the desired hole size, drill while visually checking to avoid accidentally drilling to the largest size on the bit.
