A magnetic drill is a portable drill with a magnetic base (either electromagnetic or permanent magnet). It can use twist drills, ring tools, milling cutters and other rotary tools. It can also tap, ream and countersink holes using the right drill bit. It combines a stable magnetic base with a low speed that helps resist or reduce the torque forces generated by large diameter drills. The magnetic drill with reversible motor and variable speed control can also perform tapping, countersinking and reaming operations. Magnetic drillers with cross pedestals can also perform light milling.
There are various types of magnetic drilling machines on the market, choose the best magnetic drilling machine or magnetic drilling machine for you.
There are two main types of annular tools High Speed Steel (HSS) annular tools and Tungsten Carbide Tip (TCT) annular tools. We recommend using HSS annular tools for your regular drilling operations because HSS annular tools are inexpensive, can be resharpened, and require less RPM, thus reducing the load on the magnetic drill and extending the life of the machine.
TCT ring cutters should only be used when drilling over 40 mm (1 9/16 in.) diameter, as beyond this diameter, TTCT ring cutters are cheaper and drill faster.
TCT ring cutters are also used for drilling very hard materials, such as drilling stainless steel, drilling HARDOX, drilling INOX, etc. For common metals that are not very hard, HSS ring milling cutters are the best.
Magnetic Drilling Machine
Drilling holes with a magnetic drilling machine is a three-step process:
1. The pilot pin accurately centers the cutter over the area to be drilled.
2. During drilling, the pilot pin retracts and allows the internal lubrication to reach the cutting teeth.
3. When the hole is complete, the slug/core is automatically ejected from the cutter, leaving an accurate, finished hole.
High-quality precision-engineered cutters may have tapered inner walls. These help offset the effect of frictional heat build-up that causes expansion of both the cutter and waste slug being produced by the cutting action, allowing ready ejection of the slug upon completion.
▪ Check the condition of the safety chain and the function of the switch on the magnetic drilling machine (magnetic drilling machine) before starting work.
▪ Repair of the connection cable should only be performed by a qualified electrician.
▪ Repair of the magnetic drilling machine (magnetic drilling machine) should only be carried out by an authorized specialized workshop or by the factory customer service department.
Unqualified repairs can pose a considerable risk to the user.
. Repairs to the magnetic drilling machine (magnetic drill press) during the warranty period may only be carried out by the factory's authorized customer service, otherwise the warranty is void.
▪ Defective parts may only be replaced with original equipment parts. Only these parts will ensure that safety requirements are met.
