This cutter accepts 6 APET 1604 style inserts secured by screw clamping, delivering a 0\/90 degree lead angle that produces true 90-degree shoulder walls. The tool features a 3-inch maximum cutting diameter, a maximum depth of cut of 0.64 inches, and an overall height of 1.57 inches. It mounts via a 1-inch arbor hole and is engineered for right-hand cutting direction. Part of the FM--AL series, this face mill is suited for high-productivity shoulder milling on mills and machining centers operated by skilled machinists and CNC programmers.\u003c\/p\u003e\u003cp\u003eThe OTM86427 is suited for square-shoulder face milling on ferrous and non-ferrous workpieces in both production shop and job shop environments. The 0\/90 lead angle geometry makes it effective for stepping and shouldering cuts where perpendicular walls are required. The FM--AL series designation indicates compatibility with a specific insert geometry family, allowing shops to standardize insert inventory across multiple cutter bodies. This tool is intended for use on horizontal and vertical milling machines and CNC machining centers where consistent surface finish and shoulder accuracy are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-inch maximum cutting diameter for productive face and shoulder milling passes\u003c\/li\u003e\n\u003cli\u003eAccepts 6 APET 1604 style inserts with screw-clamp insert holding for secure, repeatable positioning\u003c\/li\u003e\n\u003cli\u003e0\/90 degree lead angle produces true square shoulders in a single pass\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard spindle rotation compatibility\u003c\/li\u003e\n\u003cli\u003e0.375-inch keyway width for positive drive torque transmission through arbor mounting\u003c\/li\u003e\n\u003cli\u003eNo coolant-through design simplifies setup and toolholding requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with APET 1604 series inserts.

Ensure the machine spindle is fully powered down and locked out before mounting or removing the cutter body. Torque all insert screws using the appropriate Torx or hex key per the insert manufacturer seating procedure, and verify each insert is fully seated before starting the machine. Confirm arbor fit and keyway alignment before tightening the retention hardware to prevent runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Cutting Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 1.57 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeyway Width\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Inserts\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: APET 1604\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 0\/90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: FM--AL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.34 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: KYOCERA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: OTM86427\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA","offers":[{"title":"Default Title","offer_id":51731026444594,"sku":"OTM86427","price":677.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/005f4ff5c36537ef5542ff599b42c55b_935fbb26-c7ca-41e5-bff6-b2404ecb0dfa.jpg?v=1788726045","url":"https:\/\/voomisupply.com\/products\/kyocera-otm86427-square-shoulder-face-mill-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
