This program showcases Japan's proud manufacturing technologies, and we had the opportunity to introduce our drills under the theme "Ultimate Micro Deep Hole Challenge: Electrical Discharge Machining vs. Drilling." Our drill technology competed to drill a 60mm deep hole through a 0.5mm mechanical pencil lead, demonstrating the pinnacle of both electrical discharge machining and drilling technology.
