Description:

Twist Drill Bits:- Drilling Diameter: 4.9mm / 0.193";- Flute Length: 25mm / 0.98";- Overall Length: 45mm / 1.77";"Cutting Technology" "Spiral chip space design for fast and clean chip removal, ensuring efficient and accurate drilling results.""Wider Applications""Suitable for drilling a variety of materials including non-ferrous metals, cast iron, stainless steel, aluminum, copper, alloy steel, plastic, and wood. The drill bit's base substrate is designed without additional coatings, making it suitable for a wide range of applications.""Material Composition""Made from high-quality medium grain C2/K20 tungsten carbide, the drill bit boasts excellent toughness, hardness (HRC45), and wear resistance. This results in superior milling and cutting performance, ensuring high work efficiency and faster cutting speeds compared to other substrates."Key Features""Spiral chip space design for fast and clean chip removal""Sharp cutting edge for smooth cutting with no glitches or imperfections""Lubrication Recommendations""The drill bit is designed to be used with a suitable lubricant, which helps facilitate cutting or cooling, reducing the need for additional maintenance and improving overall smoothness and dimensional accuracy.""Machining Tips""Recommended for use on machining centers and CNC lathes.""For optimal performance, it's essential to ensure the tool clamped by the chuck is as long as possible. If the clamping length is shorter, you may need to adjust your feed rate and cutting speed to minimize vibration and extend tool life.
