It accepts a maximum width of cut of 3mm (0.118 inches) and a maximum depth of cut of 22mm, making it well suited for medium-duty cutoff work. The head measures 57.75mm in overall length with a center-to-cutting-edge distance of 10.43mm. It is configured for right-hand cutting orientation and belongs to the Beyond Evolution series. Compatible insert styles are A2, A3, and A4. Machinists and toolroom technicians install this head as part of a modular tooling system, swapping heads without disturbing the toolholder body.\u003c\/p\u003e\n\u003cp\u003eThis cutting unit head is intended for use in modular parting and grooving tooling systems on production turning equipment. The Size 50 designation matches it to the corresponding Beyond Evolution modular shank or toolblock. Typical applications include bar stock cutoff, groove turning, and face grooving on ferrous and non-ferrous materials. It is used in both job shop and high-volume production environments where quick head changes reduce downtime. The right-hand orientation suits standard forward-turning setups on conventional CNC lathe configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSize 50 modular interface for use with Beyond Evolution series toolholders\u003c\/li\u003e\n  \u003cli\u003e3mm maximum width of cut supports precision grooving and parting operations\u003c\/li\u003e\n  \u003cli\u003e22mm maximum cutting depth allows cutoff on medium-diameter workpieces\u003c\/li\u003e\n  \u003cli\u003e57.75mm head length with 10.43mm center-to-cutting-edge distance for consistent tool reach\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation for standard CNC lathe forward-turning setups\u003c\/li\u003e\n  \u003cli\u003eAccepts A2, A3, and A4 insert styles for flexibility across materials and finishes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the KENNAMETAL Beyond Evolution modular tooling system, Size 50.
