This insert has 3 cutting edges per side. The 80° cutting angle provides high cutting-edge strength for roughing, but the depth of cut is limited by the short cutting edge.

HFF – Fine Finishing For finish turning, producing smooth, accurate surfaces. Very good chip control, especially at low depths of cut

HMU – Medium Universal A medium universal geometry with a soft cutting action due to its positive geometry. Has a versatile application range, and is suited for turning unstable components and for boring applications.

The smaller point angle of this insert is more versatile for finishing and detail work, but it has less cutting-edge strength than other geometries.

HMR – Light to Medium Roughing For light to medium roughing of steels, difficult-to-machine high-alloy titanium, and aluminum materials. High strength to deal with heavy chip deformation.

HMP – Medium Positive (Single-Sided) For medium to rough turning, with reduced cutting forces and improved chip control for high feedrates. Suitable for high metal removal rates.

HMS – Medium High-Temp For medium machining in high-temp materials. Utilizes a micro-finished edge preparation to increase edge toughness.

Choose the chip breaker (geometry) based on the selected machining operation: finishing, medium, or roughing. Roughing with high depths of cut and feedrates requires an insert with a stronger cutting edge.

CCET – Finishing Positive (Single-Sided) For finishing turning operations, with optimal chip control over a wide range of cutting conditions and workpiece materials.

Choose the insert style (shape and size) based on the features of the part and the desired depth of cut. A larger nose radius is stronger, but requires more machine power, and increases the tendency for vibration. A smaller nose radius increases the access to fine part features, but has a weaker cutting edge.

For external machining and facing. The large point angle is very rigid, and good for rough machining. This is the most commonly used insert.

For internal machining. The 60° cutting angle provides medium cutting-edge strength that allows for both ID roughing and finishing applications.

Choose the insert grade (coatings) based on the type of material being cut, the specific machining operation (finishing, medium, roughing), and the cutting conditions (smooth, lightly interrupted, heavily interrupted). The insert grade and the chip breaker complement each other to provide specific performance characteristics. A tougher grade can compensate for a cutting edge with less strength, while a more wear resistant grade can provide longer tool life on a stronger cutting edge.

HUF – Ultra-Fine Finishing For finishing, with a positive cutting edge for reduced cutting forces and superior surface quality.

HUM – Universal Medium For medium-duty turning operations. Soft-cutting chip breaker. Used in applications producing varying chip sections, such as profile or copy turning. Good dimensional accuracy. For soft steel materials and stainless steels.

This price includes shipping cost, export and import duties, insurance, and any other expenses incurred during shipping to a location in France agreed with you as a buyer. No other mandatory costs can be added to the delivery of a Haas CNC Product.

HRH – Roughing Heavy For medium-duty to roughing. Outstanding chip control. High edge strength for interrupted cuts, forging skin, or scale. Preferred for all cast iron, such as gray, malleable, and nodular.

There are many variables that go into choosing the correct insert for your turning operations: insert shape, geometry, grade, and more. The goal is to select an insert that meets your requirements for quality and performance, while providing good chip control, and a reasonable combination of wear resistance and toughness.

HFP – Finishing Positive (Single-Sided) For finishing to medium turning operations, with optimal chip control over a wide range of cutting conditions and workpiece materials.

The smaller point angle of this insert is more versatile for finishing and detail work, but it has less cutting-edge strength than other geometries.

Finishing operations with light depths of cut and lower feedrates produce lower cutting forces, so cutting-edge strength is not as important. Medium turning operations, with a wide range of depths of cut and feedrate, require a more versatile geometry.

HUR – Universal Roughing Roughing geometry, with smooth chip forming and improved coolant flow for increased tool life. Positive geometry reduces cutting forces, and improves depth-of-cut notching resistance. Ideally suited for stainless steel applications, and for smooth machining of steel.
