Feature(may vary by option.)

●Twist Drill Bits: Drilling Diameter: 3.3mm / 0.13"; Flute Length: 20mm / 0.79"; Overall Length: 40mm / 1.57". Spiral chip space design for fast and clean chip removal. Sharp cutting edge provides smooth cutting and no glitches.
●Wide Applications: Used for precision cutting of alloy steel, tool steel, stainless steel, hardened steel and other high-hardness and difficult-to-machine materials. The AlTiSin composite coating has high hardness, high wear resistance and high thermal stability.
●Material: Constructed from ultra-fine DIN K45 (ISO P10) tungsten carbide, the drill bit is good toughness, high hardness and wear resistance. With good milling and cutting performance, can ensure high work efficiency. Carbide tool offers faster cutting speeds than other substrates.
●Features: Spiral chip space design for fast and clean chip removal. Sharp cutting edge provides smooth cutting and no glitches. Suitable lubricant is conducive to cutting or cooling, making cutting easier, improving smoothness and dimensional accuracy.
●Tips: Used on machining centers, CNC lathes. The longer the length of the tool clamped by the chuck, the better. If the clamping length is shorter, you need to lower the feed rate and cutting speed to reduce vibration and extend the tool life.

Information

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

Combined with the material to be processed, select an appropriate feed rate and cutting speed to improve the tool life and obtain better processing accuracy and performance.

DIN K45 (ISO P10) Tungsten Carbide

Constructed from ultra-fine tungsten carbide, the drill bit is good toughness, high hardness, wear resistance, and with good milling and cutting performance.

Composite Coatings

The AlTiSin composite coating has high hardness, high wear resistance and high thermal stability. Can ensure high work efficiency.

Spiral and Sharp Flutes

Spiral chip space design for fast and clean chip removal. Sharp cutting edge provides smooth cutting and no glitches. Cutting hardness (max.): HRC65
