Q:The threaded hole M5 general drill big bottom
General drilling screw threads diameter can be directly check the manual or by the following formula:Brittle materials (cast iron, bronze): bore diameter D=d (thread outside diameter) -1.1P (pitch)Plastic material (steel, copper, etc.): drilling hole diameter D=d (L thread diameter) -P (pitch)
Q:Method for processing coolant hole of internal cooling bit
About the processing of the inner cold hole, it depends on the material and the corresponding products. In general, cemented carbide is added to the core when the mold is fixed, and then the core material is different according to the hot melt type.
Q:What drill is best?
