KSEM PLUS modular drills feature a steel body coupled to a high-strength steel head. The head features four coolant holes and uses a combination of inserts to balance cutting forces and reduce chip load per edge. Mating the body and head is a proprietary flexible drilling system, a coupling system that uses radially activated locking screws to ensure high repeatability and minimal runout. It allows one head to fit several body length and diameter ratios. The drill body features a central coolant hole that maintains rigidity while facilitating coolant flow through the tool.
