Feature

●Specifications: twist drill diameter: 2.5 mm/0.1 inch; drill length: 80 mm/3.15 inch; shaft diameter: 2.5 mm/0.1 inch; total length: 120 mm/4.72 inch; 1 x straight shank twist drill bit
●Strength and hardness: made of cobalt steel M35 HSS (high speed steel). With high hardness and red hardness, wear-resistant and fast drilling performance.
●Surface treatment: the gold oxide surface treatment increases the hardness of the drill, ensures longer drilling life and better drilling performance and is more durable and corrosion resistant than uncoated drills.
●Professional and DIY use: suitable for drilling hard materials and carbides such as cast iron, hard plastics, but also soft materials. If it cannot penetrate, try to adjust the speed.
●Note: Please use cool and gently, the life of the twist drill can be significantly extended by proper use.
