Sensitive drilling machine

It is designed for drilling small holes at high speeds in light jobs. The base of the machine is mounted either on a bench or on the floor by means of bolts and nuts. The machine is named because of the reason that the operator can sense the progress of the drill into the work , as it is fed by hand.

Base 

The base is made of cast iron and so can withstand vibrations. It may be mounted on a bench or on the floor. It supports all the other parts of the machine on it. 

Column 

The column stands vertically on the base at one end. It supports the work table and the drill head. The drill head has drill spindle and the driving motor on either side of the column. 

Table 

The table is mounted on the vertical column and can be adjusted up and down on it. The table has ‘T’-slots on it for holding the workpieces or to hold any other work holding device. The table can 

be adjusted vertically to accommodate workpieces of different heights and can be clamped at the required position. 

Drill head 

Drill head is mounted on the top side of the column. The drill spindle and the driving motor are connected by means of a V-belt and cone pulleys. The spindle can be moved up and down by a hand feed lever. The spindle rotates at a speed ranging from 50 to 2000 rpm.
