Feature: 1.Zinc Zinc Zinc Zinc Alloy Drill Bit: This series of eccentric drill bits is made from Zinc Zinc Zinc Zinc Alloy, thoroughly hardened and ground for sharpness. The polished surface allows smoother threading, offering excellent wear resistance and durability during use. 2.Unique Four-Edge Eccentric Design: With a tilted four-edge eccentric drill bit design, positioning is more stable and penetration resistance is reduced. A hexagonal handle ensures a firm grip, providing additional security while preventing slipping . 3.High-Strength Eccentric Drill Bit: Specifically designed for hand drills, these high-strength eccentric drill bits offer precise positioning and low resistance, effectively preventing slipping and skewing. Ideal for quick drilling in concrete, brick walls, and ceramics. 4.Polished Surface for Smooth Drilling: The polished surface of these concrete brick drill bit sets reduces friction, allowing the drill bits to perform efficiently and smoothly even on tough materials like ceramic tiles and thick rocks. 5.Suitable for Various Materials: These four-edge serrated drill bits are perfect for drilling into tough surfaces. Water cooling is recommended for drilling glazed pottery, thick rock, and glass to achieve optimal results.
