Catalog number: AMD3S-3.5 Features: ●The resin ring suppresses core vibration and rattling, achieving accurate drilling. ●High-speed drilling is possible due to the drastic reduction in core contact. ●Made of high-hardness HSS (high-speed steel) steel, so the sharpness does not decrease. ●The cushion resin ring suppresses core vibration, allowing for comfortable drilling work. ●Integrated from the cutting edge to the hexagonal shaft by press processing. The drill will not come out. ●Enters the anvil smoothly and does not bite into the ball groove. ●X-shaped thinning is used. No center punch is required, and holes can be drilled with light force. Applications: ●Cutting materials: iron, light metals, synthetic resin, wood. ●For drilling various holes in iron, light metals, synthetic resin, wood, etc., and for drilling holes for tapping.
