Grades

KC7315

Composition: Multilayered PVD TiN-TiAlN coated fine-grain carbide.
Application: Applicable for steel and cast iron. This grade offers excellent wear resistance and reliability at intermediate to elevated cutting speeds.

Features and benefits

Flat bottom drills with through coolant.
Application-specific SC drills that combine two operations in one:1) Eliminate the 180° end mill in flat-bottom drilling or when preparing an inclined or curved surface for drilling.2) After full cylindrical engagement, the drill runs at normal solid carbide drilling parameters.
Unique FB drill-point design with two effective cutting edges over center enable high feed rates.
Creates a true flat-bottom hole from O.D. to center.
Four-margin land design improves hole straightness and roundness and provides good alignment, even when drilling cross holes.
Three grades-geometry-combinations available to cover most common materials.

Create Solution to calculate Feeds and Speeds
