Built in the Helitang series, this cutter holds 12 inserts and operates at a 0\/90 degree lead angle, delivering clean, square shoulders in a single pass. It accepts T490 LN 1306 insert style inserts secured by clamp and screw, and features through-coolant capability to manage heat and chip evacuation during high-demand cuts. With a maximum cutting diameter of 2.5 inches and a maximum depth of cut of 1.41 inches, it suits medium-duty face milling on machining centers and mill-turn platforms. Licensed machinists and CNC operators are the primary users.\u003c\/p\u003e\u003cp\u003eThis face mill is suited for use on vertical and horizontal machining centers where square-shoulder profiling and face milling are required. The 4-flute configuration and Helitang geometry support consistent chip flow and reduced vibration across a range of ferrous and non-ferrous workpiece materials. The through-coolant feature makes it practical for deep shoulder cuts where flood coolant cannot reach the cutting zone effectively. It conforms to ISO standards, making it compatible with ISO-compliant tooling setups common in production machine shops.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e12-insert capacity at 0\/90 degree lead angle for true square-shoulder milling\u003c\/li\u003e\n\u003cli\u003eThrough-coolant support for effective heat management and chip removal in deep cuts\u003c\/li\u003e\n\u003cli\u003eAccepts T490 LN 1306, T490 LNAR 1306, and T490 LNMT\/LNHT 1306 insert styles\u003c\/li\u003e\n\u003cli\u003eClamp and screw insert holding for secure, repeatable insert positioning\u003c\/li\u003e\n\u003cli\u003e4-flute Helitang series design for reduced cutting forces and smooth surface finish\u003c\/li\u003e\n\u003cli\u003eISO-standard construction for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible insert styles include T490 LNAR 1306 and T490 LNMT\/LNHT 1306.

Ensure the spindle is fully stopped and machine power is locked out before mounting or removing the cutter. Verify insert seating and torque all clamping screws to the tool manufacturer specification using the appropriate Torx or hex key before running the cutter. Confirm coolant line connection and flow rate before initiating through-coolant operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Cutting Diameter\u003c\/strong\u003e: 2.5 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\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.41 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 2.362 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 2.16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Length\u003c\/strong\u003e: 1.41 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutter Inserts\u003c\/strong\u003e: 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 0\/90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Style\u003c\/strong\u003e: T490 SM-13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert Size Code\u003c\/strong\u003e: T490 LN 1306\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Insert Radius\u003c\/strong\u003e: 0.031 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Insert Radius\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Helitang\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.637 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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3105094\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51732959691058,"sku":"3105094","price":1488.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9a2c2bb218080cf836826ea17a31b7d0.jpg?v=1788749577","url":"https:\/\/voomisupply.com\/products\/iscar-3105094-square-shoulder-face-mill-2-5in-helitang","provider":"Voomi Supply","version":"1.0","type":"link"}
