The Pillar Drilling Machine Model S-Itco DM 20 is a heavy-duty machine having drilling capacity in Steel 20mm, CI 22mm. The spindle is made of alloy steel accurately machined and ground, supported in precision ground alloy steel quill carrying 2 taper roller bearings. It has 4 splines as per machine tool spline standard and drives through broached sleeve. Properly balanced spindle pulley is mounted on ball bearing with bracket support for absorbing V- belt load. The spindle MT bore accuracy is 20 to 30 microns. The head is made from close-grained CI, accurately machined to ensure perfect parallelism between the column and spindle.
