5. START UP AND OPERATION
5.1 Cutters and optional equipment features.
This drilling machine’s spindle has a Weldon Shank type socket 3/4” or
19,05 mm and is specifically designed for use with annular cutters.
Annular cutter (1) is placed inside arbor body (2) and is fastened with screws
(3). While fastening the cutter in the socket, be aware that screws should be screwed
tight so that they will 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 center of a planned hole. During drilling, as the cutter goes into the 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 an annular cutter.
