Feature

●Twist drill: drill diameter: 1.5 mm / 0.059 inches; groove length: 20 mm / 0.79 inches; total length: 40 mm / 1.57 inches; cutting hardness (max. ): HRC45 Spiral chip space design for fast and clean chip removal. Sharp cutting edge ensures even cutting and no interference.
●Widely used: ultra hard universal drill metal drill. Perfect for extremely hard materials but also soft ones. Metal like steel in general, stainless steel, mild steel, cast iron.
●Material The drill bit is made of medium grain C2/K20 tungsten carbide, and has good toughness, high hardness (HRA89) and wear resistance. With good milling and cutting performance, high work efficiency can be ensured. Carbide tool provides faster cutting speeds than other substrates.
●Features: Spiral chip space design for fast and clean chip removal. The sharp cutting edge ensures a smooth cut and no interference. A suitable lubricant promotes cutting or cooling, facilitates cutting and improves smoothness and dimensional stability.
●Tips: Used on machining centers, CNC lathes. The longer the tool clamped by the chuck, the better. If the clamping length is shorter, you need to reduce the feed and cutting speed to reduce vibration and extend the tool life.

Descriptions:

Made of medium grain C2/K20 tungsten carbide, the drill bit has good toughness, high hardness (HRA89) and wear resistance. With good milling and cutting performance, high work efficiency can be ensured. Carbide tool provides long service life and faster cutting speeds than other substrates.

Widely used for drilling non-ferrous metal, cast iron, stainless steel, aluminum, copper, alloy steel, plastic, wood, etc. Designed with the base substrate without additional coatings, suitable for wide applications.

Spiral chip space design for quick and clean chip removal. The sharp cutting edge ensures a smooth cut and no interference. A suitable lubricant promotes cutting or cooling, facilitates cutting and improves smoothness and dimensional stability.

Used on machining centers, CNC lathes. The longer the tool clamped by the chuck, the better. If the clamping length is shorter, you need to reduce the feed and cutting speed to reduce vibration and extend the tool life.

Tips: In combination with the material to be machined, choose a suitable feed and cutting speed to improve the tool life and achieve better machining accuracy and performance.
