T-A Drilling System Overview Replaceable Inserts

T-A®

High Rake Notch Point® (-RN) • CombinaƟon of high rake and Notch Point geometries. • Reduces bellmouthing and leadoff. • Improves chip formaƟon in materials with very high elasƟcity/ducƟlity, extremely poor chip forming characterisƟcs, and low material hardness. Cast Iron Notch Point® (-CN) • CombinaƟon of cast iron and Notch Point geometries. • Increases stability in deep hole applicaƟons. • Specifically designed for use in grey and white cast irons. Brass (-BR) • Improves tool life due to the specialized geometry and edge preparaƟon. • Reduces self-feed tendency. 90° Spot and Chamfer (-SW) • Center cuƫng web design improves stability and strength. • Eliminates the need for a secondary chamfering operaƟon. • With added chipbreakers. Flat BoƩom (-FN) • Ideal for flaƩening or squaring the boƩom of preexisƟng holes with high rigidity. • Includes small 10° point on the nose of the insert. • Available with chipbreakers (see -FB).

High Impact Notch Point® (-IN) • CombinaƟon of high impact and Notch Point geometries. • Increases stability in deep hole applicaƟons. • Enhances chip formaƟon in materials with high elasƟcity/ducƟlity and poor chip forming characterisƟcs. Cast Iron (-CI) • Specifically designed for use in grey and white cast irons. • ExcepƟonal edge strength. • SK2 corner preparaƟon for improved tool life. • Standard geometry on K10 (C3) carbide inserts. Aluminum (-AN) • First choice for machining aluminum. • Enhanced geometry improves chip formaƟon and hole quality. • TiN coaƟng improves heat resistance and extends tool life. 90° Spot and Chamfer (-SP) • Center cuƫng web design improves stability and strength. • Eliminates the need for a secondary chamfering operaƟon. • Available with chipbreakers (see -SW). Flat BoƩom (-FB) • Ideal for flaƩening or squaring the boƩom of preexisƟng holes with high rigidity. • Includes small 10° point on the nose of the insert. • Available without chipbreakers (see -FN). Double Wide Chip SpliƩers (-DW) • Efficient cuƫng with reduced power consumpƟon. • Confident chip control in challenging applicaƟons. • Improved heat management for consistent performance.
