Feature(may vary by option.)
●[Specifications]- Twist Drill Bits Diameter: 10.5mm / 0.41-inch; Drill Bit Length: 110mm / 4.33-inch; Shank Diameter: 10.5mm / 0.41-inch; Total Length: 184mm / 7.24-inch; 1 x Parabolic Flute Drill Bit
●[Strength and Hardness]- Made of M35 HSS(High Speed Steel) cobalt 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 bit, provides longer drilling life and better drilling performance, and is more durable and corrosion resistant than uncoated drill bits.
●[Parabolic Flute]-The parabolic flute adopts a wide groove structure to increase the chip flow rate and ensure fast and easy chip removal and rapid penetration.
●[Note]- Please keep cool and gentle using, the working life of the twist drill bits can be largely prolonged by proper usage
