2.8mm Countersink Drill Bit, 8mm Round Shank, HSS Woodworking Cone Drill Chamfer Counter Bit, Screws Hole Tool for Wood Drilling

• Good Countersinking Effect: The design of the countersink drill bit allows it to effectively remove wood chips during drilling, preventing chip accumulation and resulting in cleaner and neater holes, thereby improving the countersinking effect.
• Fast Drilling Speed: The design of the countersink drill bit enables faster drilling, increasing work efficiency. The diameter of the countersink drill bit shank is 8mm and 10mm, and the diameter of the drill bit is 2.8mm, 3mm, 3.2mm, 3.5mm, 4mm.
• Strong Applicability: The countersink drill bit is suitable for various types of wood, including softwood, hardwood, engineered wood, plywood, fiberboard, particleboard, plastic, etc., making it highly versatile.
• Accurate Drilling Position: The design of the countersink drill bit enables it to maintain accurate drilling position, resulting in more precise hole drilling. The length of the drill bit can be adjusted by loosening and tightening the screw for different screw lengths.
• Long Service Life: The countersink drill bit is made of high-quality alloy steel, which is hard and wear-resistant, providing excellent cutting ability and long service life. It can be used multiple times under normal conditions.
