A mag base drill is a portable drilling machine with a permanent magnetic base. It is best suited for large and heavy work pieces which are difficult to move for making holes. They are portable and lightweight so they can be easily taken to the workpiece to be drilled. The strong magnetic base of the drill sticks to the metal surface to stabilize the drilling process.

These drill are often used in steel fabrication, building, construction, and many other applications where drilling stability might be required.

How to use a mag base drill?

1. Choose the right bit for the material to be drilled.
2. Select the correct ejector pin for the cutter length.
3. Insert the ejector pin inside the annular cutter. Never use an annular cutter without an ejector pin.
4. Insert the annular cutter in the machine arbor and tighten the screws correctly.
5. 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 over the mark.
6. After positioning the machine on the mark where the hole is to be made, switch on the magnet switch.
7. Fill the coolant tank with lubricant or cutting oil. Never use the machine without lubricant.
8. Switch ON the motor switch and start to drill with slow feed. Never crash the cutter on to the material.
9. Start to drill with firm steady feed rate. Too slow or too fast feed rate will damage the cutter.
10. Putting too much pressure on the feed handle will not make drilling faster; rather it will break the cutters.
11. Drill with less pressure and steady feed for best results and longer service life of annular cutters
12. To prevent long chips forming you should use reverse feed when cutting deep holes.
13. To prevent accidents clean the work area.

Important

• Below 40 mm diameter drilling always use HSS annular cutter. HSS annular cutters compared to TCT annular cutters are price economical, re-sharpen able, re-usable, needs less power.
• Always use special lubrication for drilling.
• While drilling with annular cutters, feed pressure should not be too low or too high, let the cutter cut the material by rotating and not by vertical pressure. Applying more pressure will not make faster holes, rather it will damage the armature of the machine and damage the annular cutter.
