Why are Three-Flute Drills Better? | Fabricating and Metalworking

As well as reliable chip evacuation, the force and torque characteristics of three-flute drills must also be taken into account because there are higher feed forces due to the design. The test series have shown that with the same cutting data, different feed forces occur depending on whether it is a two or three-flute drill design.Get price

Ejectors and Eductors Selection Guide | Engineering360

FeaturesTypesSpecificationsApplicationsEductors use the kinetic energy from a stream of compressed gas or liquid. The movement of this stream through a tapered tube and Venturi nozzle increases the pressure of the flow. The subsequent discharge of the stream then creates an area of low pressure that draws in the contents of the suction chamber. Mixing occurs in the diffuser and the motive fluid is released through an exhaust port. Often, eductors are made of polytetrafluoroethylene (PTFE), a fluorinated thermoplastic with outstanding chemical resistance and excellent lubricity. Eductor nozzles are usually made of stainless steel.Get price
