Operator’s manual for drilling machine

 

- 9 - 

5.  OPERATING INSTRUCTIONS 

The  drilling  machine  has  a  spindle  with  Morse  Taper  MT3  to  use  twist  drill  (by  using  the 

reduction adapter if necessary)  and  annular c

utters. Arbor mark AMT is mounted in spindle conical 

taper to fix annular cutters. 

Milling cutter (2) is located inside arbor body (1) and is fastened with screws (3). While fastening the 

cutter in the socket, be aware that screws should be screwed tight so that they could not come 
unscrewed. It is important to position the cutter in relation to the socket in such a way that fixing flats 

on the cutter shank are positioned opposite to the fixing screws (3). Both fastening screws (3) should 

be used to fasten 

the cutter. Pilot (5) is located inside the cutter. It makes it easier to position milling 

cutter over centre of a planned hole. During drilling as the cutter goes deep into steel, the pilot moves 

back  into  the  arbor  body  and  tightens  discharge  spring  (4).

  That spring ejects slug which is a by-

product of milling a hole with a centre free cutter (Drawing No. 3).
