Description:
The fine particle tungsten steel base material is adopted, which has high hardness, strength and wear resistance to ensure the stability of each tungsten carbide drill bits ; The edge is covered with nano coating, which can directly rough process to fine process the 55 degree heat treatment material, reduce the number of tool changes, improve the machine tool productivity, and explain the production aging; CNC fine grinding of double rear corners effectively improves chip removal performance, making cutting sharper and drilling faster; Universal round handle chamfer design, wide application range, convenient and durable.

Parameter:
3D/5D External Cooling Cutting Parameters
3D/5D internal cooling cutting parameter
- When using this tungsten carbide drill bits for the first time, try to cut at 90% of the cutting speed or 85% of the feed speed according to the above data, and then increase the cutting speed and feed rate one by one after the cutting condition is stable
- This standard cutting condition is applicable to water-soluble cutting fluid
- When installing the tool, please use a clean chuck with defects removed, and control the radial runout of the drill bit within 0.02mm
- The cutting conditions in this table are applicable to situations with hole depth below 5D
Notice:
- When drilling steel parts, please ensure sufficient cooling capacity and use metal cutting fluid.
- Good drill pipe rigidity and guide rail clearance can improve drilling accuracy and bit life.
- Please ensure the flatness and cleanness between the magnetic base and the workpiece.
- When drilling thin plates, reinforce the workpieces. When drilling large workpieces, ensure that the workpieces are stable.
- At the beginning and end of drilling, the feed rate shall be reduced by 1/3.
- For materials with large amount of fine powder during drilling, such as cast iron, cast copper, etc., compressed air can be used instead of coolant to help remove chips.
- Please remove the iron scraps wrapped on the drill body in time to ensure smooth chip removal.
Applications:
Our tungsten carbide drill bits could to be processed Alloy steel, Tool steel, carbon steel, stainless steel, Cast iron and Titanium alloy. Working material as following:
