Available in three original chipbreaker styles, the inserts feature improved chip control and reduced cutting force for use in low- rigidity contexts. J DesignCutting force of central insert ≈ that peripheral blade ■ Features and Applications ● Balanced Design Cutting force during drilling is balanced between central insert and Central Insert peripheral insert. The relative position of each insert is optimised to provide stable drilling. Peripheral Insert ● Excellent Chip Control The chip evacuation direction can be controlled with the chip control groove at the centre of the breaker, enabling good chip control. ● Versatile Tool for a Variety of Machining Applications Select among three types of breakers for different applications, allowing optimal drilling for a variety of work materials and conditions. Suitable Chip control groove for a wide range of applications including hole expansion, spot facing, in each cutting edge external turning and internal boring. ● Economical Four-Cornered Insert This product has an extremely economical design where a single insert type can be used for the central insert or peripheral insert, with two corners for each position - a total of four corners.
