SumiDrill WDX Type ■ General Features SumiDrill WDX type has excellent cutting balance that provides stable hole drilling on a wide range of work materials from general steel to stainless steel and aluminum alloy. Available in three original chipbreaker styles, the WDX type features improved chip management and reduced cutting force for use in low rigidity set ups. Design Cutting force of central insert 〜〜 that of peripheral insert ■ Characteristics and Applications D Balanced Design Cutting force during machining is balanced between central and peripheral inserts, and the relative position of each insert are optimised to provide stable drilling. D Excellent Chip Control The chip control groove in the center of the breaker provides good chip control by controlling the direction of chip evacuation. D Versatile Tool for a Variety of Machining Applications Three separate purpose-designed breakers enable optimal drilling with a variety of different work materials in a variety of different conditions. Applicable to a variety of operations including hole expansion, spot facing, Chip management external turning, and internal boring. groove on each D Economical, Four-Cornered Insert cutting edge Inserts can be used in both central and peripheral positions, with two corners for each position - a total of four corners - for excellent cost- effectiveness.
