Key features

• Premium HSS With Titanium Coating - Made of high-speed steel with titanium coating, these drill bits feature sharp edges for faster, effortless drilling. The fully ground spiral groove design quickly decreases friction and heat, ensuring a cooler and more efficient drilling performance
• 135° Split Point & Round Shank - The 135° split point with a straight shank prevents walking and ensures precise starts. The sharp edge makes drilling faster and more effective. The universal round shank fits most electric drills and bench drills securely without slipping, making it a great addition to your drill bit collection
• 2-In-1 Serrated Side Cutting Design - Unlike standard drill bits, the sharp serrations on the side allow you to continue cutting horizontally after drilling. Perfect for pulling grooves and slotting. For best results, please saw in the OPPOSITE (Counter-clockwise) direction to the drill rotation

Suitable for drilling on wood, plastic board, aluminum, thin iron sheet, and copper tubes. Ideal for slotting or cutting 1mm-2mm thin wood, solid wood, MDF, and multilayer board. Comes with a portable plastic bag for easy storage
• Critical Usage Guidelines For Grooving - To achieve successful cutting and avoid burning the bit, please follow these tips: 1. Power & Speed: A high-power drill (24V+ or 350W+) is crucial. Cordless drills below 24V or Corded drills below 350W are NOT recommended. Larger diameters drill bits require slower speeds; use low speed and high torque for cutting; 2. Edge Cutting: If cutting from the edge, the bit may slip due to the lack of a fixed point. Start with a smaller drill bit and control the speed. It is NOT recommended to use bits larger than 8mm for cutting
