The Tamiya 69903 3.5mm bit is a straightforward upgrade for users of the Modeler's Punch (Item 74122), enabling neat small holes for masking and assembly jigs. It performs well on masking tape and plastic boards up to 0.5mm thickness, expanding the punch's usefulness.
Crafted from chrome molybdenum, the bit is durable and made to long service life when used as intended. It fits the Modeler's Punch (Item 74122) and supplies a hole size not included in the basic selection. Always remove any protective oil before first use and ensure a secure fit in the punch head.
