A magnetic drill is a portable drill with a magnetic base (either electromagnetic or permanent magnet).It can use twist drill bits, annular cutters, milling cutters, and other rotary cutters. 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.Portable magnetic drills are faster and more portable than drills such as drill presses and are more accurate than hand drills.
Portable magnetic drilling machine for steel or other magnetic materials. It provides accuracy of 0.01 mm to 0.05 mm in steel or other magnetic materials. The drill bits used in this machine are usually made of high speed steel (HSS) or tungsten carbide (TCT).
Magnetic Drilling Machine
Electromagnetic drilling machines are best suited for most jobsite situations where electricity is sufficient and the work environment is relatively dry.
Pneumatic magnetic drilling machines, which have access to a compressor and where the job site may be wet or in a hazardous environment.
Hydraulic magnetic drilling machines are mainly used for industrial, construction and offshore drilling applications.
A magnetic drill press is essential when cutting or drilling holes in steel. You can line up the drill bits and hold them in place, which will reduce wear and tear on the body while drilling. If you have the budget, buy a magnetic drill with a swivel base. This makes it easier to line up the drill bits on the holes.
Annular Cutter
Drilling with a magnetic drill is a three-step process.
1. The guide pin aligns the tool exactly to the area to be drilled.
2. During the drilling process, the guide pin retracts and allows internal lubrication to reach the cutting teeth.
3. When drilling is complete, the blank/core is automatically ejected from the tool, leaving an accurate finished hole.
High quality precision designed tools may have tapered inner walls. These help counteract the effects of frictional heat buildup, which causes the cutter and scrap from the cutting action to expand so that the scrap can be drained at any time after completion.
