Radial Drilling machine

Drilling machine which is used to drill the holes on the components or work piece with the help of drill bits.

The drill bits are also called as Multi-point cutting tools which can have their rapid impact on the Material Removal Rate (MRR) i.e. a single point cutting tool(like the one used in a lathe machine) can removes the material slowly whereas, a multi-point cutting tool removes the material at a faster rate and thereby increases MRR.

Basic parts of a Drilling Machine include:
1.Base(Bed):
2.Column
3.Swivel Table
4.Power Transmission system:
5.Hand wheel:
6.Chuck: It is used to hold the drill bit.

The drilling machine available in the central workshop is EIFCO- RDH- A325
