Kennametal is expanding its KSEM PLUS range by introducing new KSEM PLUS B1 Heads with DFC guiding pads to deliver reduced cost per hole in difficult drilling conditions.

The KSEM PLUSTM modular system combines the benefits of the KSEMTM modular drill (high feeds and length-to-diameter [L/D] ratios) with the benefits of an indexable drill (high speeds and low consumable costs).

The B1 Heads can drill through stacked materials, inclined exits, cross holes, and interrupted cut conditions. The new pads give the KSEM PLUS B1 Heads accurate guidance of the head when drilling through cross holes with widths up to 50 per cent of the drill’s diameter. They also eliminate spiral marks and grooves and enable high-quality hole exits for reliable drilling from two sides when indexing drilling directions.

KSEM PLUS B1 Heads offer two effective cutting edges that work well at high feed rates to reduce the load per edge, compensate for radial forces, and prevent disk build up with only two chips per edge. They are available in standard sized from 28–70mm and customized solutions from 28–127mm.
