PVD-TIN coated fine grade carbide
High egde strength and transfers rupture strength
For difficult cutting tasks with interrupted cuts
First Choice in solid carbide drills for many steel materials and tough cast iron materials
Also for indexable inserts
Features and benefits
- SE four-margin drills with through coolant for steel.
- Application-specific SC drill for mid-L/D applications that require high accuracy and consistent hole straightness combined with excellent metal removal rates and long tool life, such as in conrods.
- SE drill point design with sculptured edge enables high feed rates.
- KC7315™ grade is a multilayer, TiAlN-based coating with high hot hardness allows 30% higher cutting speeds and constant tool life.
- Four-margin lands improve hole straightness and hole alignment when drilling through cross holes.
