Kennametal's new KSEM PLUS B1 heads.

The KSEM PLUS modular system has the KSEM modular drill (featuring high feeds and length-to-diameter [L/D] ratios) and an indexable drill (with high speeds and low consumable costs).

Kennametal's B1 Heads can handle drilling through stacked materials, inclined exits, drilling through cross holes, and interrupted cut conditions. They feature DFC guiding pads which give accurate guidance of the KSEM PLUS B1 Heads when drilling through cross holes with widths up to 50% 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 have two cutting edges that work 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.
