Steel drill bits to be used with Japanese Screw Punch. The Japanese Screw Punch is the perfect tool for making holes in a multitude of materials, including cloth, paper, board and leather. Great for stab bindings, portfolios and fabric covers. Made in Japan (beware of cheap imitations!). The screw punch makes holes quickly and cleanly when pushed into the material to be cut. Lovely smooth action, and best done onto a cutting mat to protect the drill bits.
