There are various types of magnetic drilling machine available in the market, chose the best suitable magnetic drilling machine or magnetic drill press for your purpose. The types of magnetic drilling machines are details in our previous article: Types Of Magnetic Drilling Machine

Types of Magnetic Drill Press


B. Selection Of Annular Cutters:

Mainly annular cutters are of two types High-Speed Steel (HSS) Annular Cutters and Tungsten Carbide Tip (TCT) Annular Cutters. We recommend the use of HSS Annular Cutters for your regular drilling jobs because HSS annular cutters are cheaper in price, can be re-sharpen, need less RPM which reduces the load on your magnetic drilling machine and increases the machines’ service life. The TCT Annular Cutters must only be used while drilling more than 40 mm (1 9/16 inches) diameter because above this diameters the TTCT Annular Cutters get cheaper in price and are more faster to drill. The TCT Annular Cutters should also be used while drilling very hard material like for drilling stainless steel, drilling HARDOX, drilling INOX, etc. For normal metal which is not very hard, HSS Annular Cutters are the best.

C. Below Are The Instructions On How To Use A Magnetic Drill Press And An Annular Cutter Professionally:

  1. Select the correct annular cutter for the material to be drilled.
  1. Select the correct ejector pin for the cutter length.
  1. Insert the ejector pin inside the annular cutter. Never use an annular cutter without an ejector pin.selecting annular cutter

  1. Insert the annular cutter in the machine arbor and tighten the screws correctly.
  1. Move the machine towards the mark where the hole is to be drilled and with the help of the pilot pin locate the mark by touching the tip of the pilot pin tip over the mark.
  1. After positioning the machine on the mark where the hole is to be made, switch on the magnet switch of the magnetic drilling machine. Check if the magnet indicator glows GREEN. If, the magnet indicators glows RED that means the magnet does not have enough material below for a perfect adhesion. In an ideal condition, the thickness of the material to be drilled must be minimum 8 mm (5/16 inches)clamping annular cutter

  1. Fill the coolant tank with lubricant. Never use the machine without lubricant. for HSS annular cutters use cutting oil and for TCT annular cutters use water soluble coolant.
  2. Set the correct RPM on the machine for the size of the cutter being used. The formula for calculating RPM (n) is n = (v X 1000) / ( d X 3.14). Where v is the cutting speed of the annular cutter and d is the diameter of the annular cutter. You can also use our website to automatically calculate the RPM.

10. You must use the internal lubrication when drilling with annular cutters and also use external lubrication when drilling above 50 mm (1 15/16 inches) thickness.

11. Switch ON the motor switch of the magnetic drill press and start to drill with slow feed. Do not crash the cutter on to the material.

12. Start to drill with a firm steady feed rate. Too slow or too fast feed rate will damage the annular cutter.

13. Check if the lubricant is coming out. Use a lot of lubricant for good results.

14. Putting too much pressure on the feed handle will not make drilling faster; instead, it will break the annular cutters.

15. Drill with less pressure and steady feed for best results and longer service life of annular cutters.Guide To Use Magnetic Drill press


16. To prevent long chips forming you should use reverse feed when cutting deep holes.

17. To prevent accidents clean the work area with BDS PowerWORKER or appropriate cleaning tool after drilling.

18. Perfect drilling with the above instructions will result in perfectly finished holes, in less time and with more service life of both cutter and machine.Use Magnetic Drill press
