WC-type inserts are the most commonly used drill inserts in metalworking world. Indexable insert drills can be used in boring operations in order to save tool changing time. Plunge drilling is an effective method for roughing out cavities.
It makes a deeper hole or cavity through repeated axial cuts using a drill or milling cutter and is especially suitable for rough machining. It is power-efficient, productive and reduces demands on the machine tool spindle as the main cutting forces are directed axially along the spindle.
Internal plunge milling is started by drilling a hole for the plunging tool. The special –PG chipbreaker has unique design of corrugated edge ensures high edge strength and good chip breaking performance.
