A portable magnetic drilling machine is faster and more portable alternative to hole making machines such as the drill press, and is more accurate than a hand drill. A portable magnetic drilling machine is used on steel or other magnetic materials. It gives an accuracy of 0.01 mm to 0.05mm in steel or other magnetic material. The drill bits ...
Usually, for these machines, it is better to use cutters because they can drill much faster with less speed. Cutter sizes vary from 12mm to 200mm DIA and from 30mm to 200mm DOC(depth of cut). These machines are widely used in construction, fabrication, marine, and oil & gas industries.

Computer numerical controlled (CNC) machines are computer-driven tools that can machine a large variety of shapes, and whose use in the workflow depends on the part to be machined. [2] CNC machines are becoming the standard due to their speed, precision, flexibility, repeatability, and reduced downtime while changing jobs.
The largest machines can handle stock up to 3 in (76 mm) wide, 12.5 in (320 mm) long, and 3 ⁄ 32 in (2.4 mm) thick. For wires the limit is 1 ⁄ 8 in (3.175 mm). [ 3 ] Other limits are the travel on the slides, which maxes out at 3 ⁄ 4 in (19.05 mm), and the throw of the forming cams, which is between 7 ⁄ 8 and 2 in (22 and 51 mm).
