26-piece Countersink Drill Bit Set

Woodworking chamfering bit set: 4 standard chamfer bits and 4 four-flute chamfer bits, compatible with stationary drilling machines, handheld drills, or other professional drilling equipment. To prevent slipping or eccentricity during drilling, we recommend using a stationary drill press or securely clamping the drill bit. [7-piece tapered wood drill bits] Made of high-carbon steel with a titanium coating, the drilling depth can be adjusted for different lengths. The chamfer features 5 flutes designed to work with the 6-piece tapered drill bit set, allowing faster wood drilling. 1/4-inch 90-degree hex shank – made from standard high-speed steel (HSS). HSS tapered drill bits undergo high-frequency quenching heat treatment, providing excellent strength and hardness. The titanium-coated chamfer set is rust-resistant and long-lasting. [3-piece stepped tapered drill bit set] Made of titanium-coated high-speed steel, the hex shank of the stepped drill features grooves for a firmer grip in electric drills, making it suitable for drilling thin stainless steel, carbon steel, aluminum plates, iron plates, etc. Includes 1 automatic center punch with a dimple to create an initial starting point and prevent workpiece movement. We offer various wood drill bits that can be used for any required hole size.
