Drilling through stacked papers without tearing or shifting requires mechanical advantage, not force. Aitoh's Screw Punch delivers exactly that through its brass screw mechanism, which converts rotation into controlled downward pressure. Turn the wooden handle and watch the bit advance steadily through multiple sheets, creating clean holes without the ragged edges that standard hole punches leave behind.

The solid brass threading ensures smooth, consistent operation that won't strip or bind over time. Hardened carbon steel bits (sold separately in three sizes) maintain their cutting edges through hundreds of holes, whether you're binding handmade books, creating leather-hinged portfolios, or preparing papers for traditional Japanese binding techniques. The wooden handle provides comfortable grip during extended binding sessions.

This tool excels where precision matters: registration holes for multi-color printmaking, exact placement for sewn bindings, centered holes in heavy cover stock. Replace worn bits rather than the entire tool, making this a long-term investment for bookbinders and paper artists who need clean, accurately positioned holes every time.
