Description:
- High speed steel M35 is preferred, with high hardness, stable performance, sharp and durable
- Double thread chip removal groove ensures smooth chip removal and improves the working efficiency of the tungsten carbide drill bits.
- Fully ground double cutting edges, stable size and good finish, reduce the friction coefficient of drilling hole, and the hole wall is smooth with high accuracy
- Large spiral groove design, large chip holding space, smooth chip removal, effective prevention of chip residue, good chip removal performance, fast drilling speed
- The tail chamfering is easy to install, and the clamping is firm without slipping, with a wide range of applications

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:
