Crownloc™ Plus is a new generation of Seco drills with exchangeable crowns. Featuring a new geometry, coating and locking interface, Crownloc Plus improves chip evacuation and wear resistance in a variety of materials.

Crownloc Plus features a strong drill body design, high-strength locking interface with deep and wide flutes and polished body. The drill’s crowns have a new optimized geometry for improved chip formation and enhanced entering capability. The combination of a TiAlN coating, low-friction TiN coating on the exchangeable head and 10% micrograin substrate serve to increase toughness and wear resistance, while reducing the potential for edge build up.

The first choice for general applications, the P geometry is a strong and versatile solution that provides reliable operation in applications across a range of different workpiece materials. Utilizing a free cutting drill point to minimize heat generation, the M geometry provides excellent performance in high temperature alloys, titanium, titanium alloys and stainless steel.
