Hex Shank Twist Drill Bits Titanium Coated High Speed Steel Quick Change Hex Drilling Bit Jobber Drill Bits For Wood Plastic Metal - 10 / 1.5Mm

1. The hexagonal shank twist drill is made of high-speed steel, which has excellent hardness, wear resistance and heat resistance, and is not easy to deform or damage.2. The gold-titanium coating on the surface of the high-speed steel drill bit improves corrosion resistance and hardness, enhances the wear resistance and scratch resistance of the drill bit surface, and has good anti-oxidation properties and is not easy to rust.3. The widened spiral groove design can quickly remove particles, reduce friction and heat, and achieve faster and cooler drilling performance.4. The 135° pointed head design is more labor-saving and has good radial stability to prevent movement and make drilling precise without center punching.5. The twist drill bit set can meet the drilling needs of woodworking, home repair, metal processing, construction, etc. It can be used for drilling operations in a variety of materials such as wood, metal, plastic, etc.6. Jobber drill bits are often used with hand-powered drills. During work, ensure that the hexagonal shank and the electric drill are firmly installed to avoid looseness.
