기능

• The resin ring suppresses wicking and rattling to achieve accurate drilling.
• High-speed drilling is possible due to drastic core run-out.
• Good bite and no punch (marking to center the hole to prevent the drill tip from escaping). (Adopted for effective φ3.0 mm or more.)
• High hardness HSS (High Speed Steel) for sustained sharp sharpness.
• A grooved drill is integrated with a press stop on the shaft. (In order to enhance the bonding strength, 2 surface cuts have been made for φ1.8 mm and above.)
• Work Material: Iron, Light Metal, Synthetic Resin, Wood.
