2. Magnetic drilling machine - Wikipedia

   en.wikipedia.org/wiki/Magnetic_drilling_machine

   A morse taper 3 arbor equipped magnetic drill machine using taper shank drill bits. The arbor or chuck on a magnetic drill is attached to the motor. It is a type of clamp used to attach the core drills. There are mainly two types of chuck available for the magnetic drill, industrial arbor (manual tightening) and quick change drill chucks.

3. Annular cutter - Wikipedia

   The tube clamping device is a metallic device that is clamped on the tube with an adjustable chain. After clamping the device the magnetic drilling machine is placed on the device, which gets clamped to the device by switching on its magnet. With the help of magnetic drilling machines' proper RPM, the annular cutter makes a perfect hole in the ...

4. Punch (tool) - Wikipedia

   en.wikipedia.org/wiki/Punch_(tool)

   A center punch forms a large enough dimple to "guide" the tip of the drill. The tip of a center punch has an angle between 60 and 90 degrees. [1] When drilling larger holes, where the drill bit is wider than the indentation produced by a center punch, the drilling of a pilot hole is usually needed.

5. Drill - Wikipedia

   A magnetic drill is a portable machine for drilling holes in large and heavy workpieces which are difficult to move or bring to a stationary conventional drilling machine. It has a magnetic base and drills holes with the help of cutting tools like annular cutters (broach cutters) or with twist drill bits. There are various types depending on ...

6. Drill bit - Wikipedia

   While the above is a common use of center drill bits, it is a technically incorrect practice and should not be considered for production use. The correct tool to start a traditionally drilled hole (a hole drilled by a high-speed steel (HSS) twist drill bit) is a spotting drill bit (or a spot drill bit, as they are referenced in the U.S.). The ...

   This process is faster, but is only used in moderately long holes, otherwise it will overheat the drill bit. It is also used when drilling stringy material to break the chips. [8] [9] [self-published source?] [10] When it is not possible to bring the material to the СNС machine, a Magnetic Base Drilling Machine may be used.
