Built to KM16 system size, this right-hand cutting head accepts A4S inserts from the Micro A4 series and delivers a maximum depth of cut of 0.6299 inches (16.00 mm). The minimum groove width starts at 0.0787 inches (2.00 mm), making it well-suited for tight, close-tolerance grooving work. Licensed machinists and tooling technicians install this head as part of a modular quick-change setup, reducing changeover time while maintaining repeatable cutting geometry.\u003c\/p\u003e\u003cp\u003eThis cutting head is intended for use in modular grooving tooling assemblies operating on CNC lathes and turning centers that accept the KM16 interface. It is part of the Kennametal Micro A4 series, which targets small-diameter and fine-pitch grooving applications common in precision machining of aerospace, medical, and general metalworking components. The 0.3937-inch (10.00 mm) center-to-cutting-edge measurement and 1.1811-inch (30.00 mm) head length projection are critical reference dimensions when programming tool paths or selecting a compatible boring bar or toolholder body.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKM16 modular interface for quick, repeatable head changes on compatible toolholders\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard OD and ID grooving operations\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.6299 inches (16.00 mm)\u003c\/li\u003e\n\u003cli\u003eMinimum groove width of 0.0787 inches (2.00 mm) for fine-pitch grooving\u003c\/li\u003e\n\u003cli\u003eAccepts A4S insert style from the Micro A4 series\u003c\/li\u003e\n\u003cli\u003eHead length projection of 1.1811 inches (30.00 mm) for precise tool-path programming reference\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KM16 modular tooling bodies that accept Micro A4 series grooving heads and A4S style inserts.

Disengage machine power and confirm the spindle is fully stopped before mounting or removing the grooving head. Follow the toolholder manufacturer's clamping and torque procedures for the KM16 interface to ensure secure seating and repeatable tool position. Verify insert style and orientation before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Size\u003c\/strong\u003e: KM16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Micro A4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModular Head Style\u003c\/strong\u003e: Cutting Head\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert Style\u003c\/strong\u003e: A4S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.6299 inches (16.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Groove Width\u003c\/strong\u003e: 0.0787 inches (2.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.3937 inches (10.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length Projection\u003c\/strong\u003e: 1.1811 inches (30.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.001 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3377202\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744873611570,"sku":"3377202","price":366.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aad43c08e6cf099cbf5b5d2561dbd808_2ae1020b-5e09-492a-8c40-5e73a9bb997b.jpg?v=1788861812","url":"https:\/\/voomisupply.com\/products\/kennametal-3377202-modular-grooving-head-km16-a4s-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
