Below is the RPM Chart For Annular Cutters and RPM Formula For Annular Cutters. Setting exact RPM as per the annular cutter diameter helps increase annular cutter life and magnetic drilling machine life.
A magnetic drilling machine performing tapping (thread cutting) on a flange. One of the best features of a magnetic drilling machine is to perform Tapping, also called as Thread cutting. The magnetic drilling machines with reversible motors are ideally suited for thread cutting. The basic requirement for a magnetic drilling machine to perform thread cutting.
The fast and easy method to drill holes in metal, is with the help of Annular cutters, also called as annular cutters, core drills, etc. Following pictogram images will show you how one can use annular cutters like a professional. Carefully practicing the following method of drilling will help you get more holes per cutters,.
Time saving As a annular cutter cuts only on the periphery of the hole to be made, it has to remove much less material as compared to conventional drill bits which cut and remove the complete material of the hole. Annular Cutters are considered to be 3 to 4 times faster than conventional drill bits..
Using lubricant or coolant with any type of annular cutter is a must. A correct lubrication and coolant delivery more life for annular cutters. The very important thing to know is that TCT annular cutters require Coolant, not lubricant and HSS annular cutters required Cutting oil, not coolant. For TCT (Tungsten carbide tipped) annular cutters.
This is a question in everyone’s mind, which type of annular cutter should we prefer HSS or TCT. Below information gives you a brief clarification. Cost HSS annular cutters are cheaper than the TCT annular cutters for smaller diameters up to 40 mm, while TCT annular cutters are cheaper than HSS for diameters above 41 mm..
The below video and poster will give you expert information on how to professionally use annular cutters for better performance, longer life, and saving tool cost.
The ejector pin or also called as the pilot pin has 3 major functions to use with annular cutters: Centering: The ejector pin is exactly positioned to the center punch mark. Switch the magnet on and the machine and annular cutter are in the drilling position. Oiling: By means of the automatic internal lubrication, cutting oil is.
