With a 1.5-inch cutting diameter and a maximum depth of cut of 0.656 inches, this tool handles both roughing and semi-finishing passes in steel, cast iron, and similar workpiece materials. It accepts three indexable inserts held by screw clamping, allowing worn edges to be rotated or replaced without removing the body from the spindle. The 3\/4-inch Weldon flat shank seats securely in standard end mill holders. Overall length is 3.25 inches. Machinists and toolroom operators working on CNC vertical mills and manual knee mills are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for square-shoulder facing, slotting, and step milling in both production shop and toolroom environments. The three-insert configuration provides three cutting flutes, supporting moderate feed rates while keeping cutting forces manageable. The Weldon flat shank design ensures positive drive and minimal pullout risk under side-load conditions typical of shoulder milling. It is appropriate for horizontal and vertical milling machine setups where a rigid, side-locking holder is used.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.5-inch cutting diameter with a maximum depth of cut of 0.656 inches for square-shoulder profiling\u003c\/li\u003e\n  \u003cli\u003eThree indexable insert pockets with screw clamping — accepts TPC 32, TPG 32, and TPU 32 style inserts\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch Weldon flat shank for positive, pullout-resistant drive in standard end mill holders\u003c\/li\u003e\n  \u003cli\u003e3.25-inch overall length suits typical spindle clearance on vertical machining centers and knee mills\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through passages — external flood or mist coolant delivery required\u003c\/li\u003e\n  \u003cli\u003eSingle-piece body design allows quick insert indexing at the machine without full tool changeout\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with TPC 32, TPG 32, and TPU 32 series indexable inserts.

Use a torx or hex key of the correct size to secure insert screws to the manufacturer-specified feel — do not overtighten, as insert seats can crack. Confirm shank seating depth and set-screw engagement against the Weldon flat before tightening the holder. Verify runout with a dial indicator before beginning a cut, particularly when switching insert grades or geometries.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.656 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.219 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutter Inserts\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: TPC 32, TPG 32, TPU 32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\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: 0.85 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6-901-020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693324697906,"sku":"6-901-020","price":387.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1f01ab4a83bae21166ca6c2df701cde.jpg?v=1788310657","url":"https:\/\/voomisupply.com\/products\/value-collection-6-901-020-indexable-square-shoulder-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
