Built to the MM12 Minimaster series standard, this indexable tip features a 45-degree chamfer angle, a 90-degree included angle, and a 0.472-inch cutting diameter. The tool material is solid carbide with a PVD-applied TiAlN coating, which provides thermal resistance and extended tool life across a range of workpiece materials. With two flutes and a right-hand cut orientation, this tip is installed by machining professionals on compatible Minimaster-series holders for precision chamfering, spot drilling, and countersinking work.\u003c\/p\u003e\n\u003cp\u003eThis tip is suited for use on a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The M04 chipbreaker geometry is optimized for controlled chip evacuation in these material categories. Typical applications include chamfering drilled holes, preparing surfaces for fasteners, and producing countersunk features on machined parts. The tip is sized for the MM12 Minimaster toolholder system and is intended for use on CNC machining centers where repeatability and quick tip changes are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45-degree chamfer angle with 90-degree included angle for consistent chamfer geometry\u003c\/li\u003e\n  \u003cli\u003e0.472-inch cutting diameter with 0.222-inch maximum depth of cut\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction, grade C5, with PVD TiAlN coating for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003eTwo-flute, right-hand cut design with M04 chipbreaker for controlled chip flow\u003c\/li\u003e\n  \u003cli\u003e0.576-inch functional length; fits MM12 Minimaster-series holders\u003c\/li\u003e\n  \u003cli\u003eCompatible with steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards; manufactured under catalog number 74034542\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with MM12 Minimaster-series milling toolholders.

Before changing the tip, ensure the machine spindle is fully stopped and the toolholder is removed or locked out per shop safety procedures. Use the appropriate Minimaster torx key to seat and torque the tip according to the toolholder manufacturer specifications. Do not exceed the maximum depth of cut of 0.222 inches to avoid tip overload or premature failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.472 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.222 inches (5.7 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.576 inches (14.64 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Carbide, Grade C5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN (PVD process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: M04\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MM12 Minimaster\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 74034542\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563870126386,"sku":"74034542","price":180.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f5d885ffb2bb41eaf50a21c304f9e2c.jpg?v=1786505528","url":"https:\/\/voomisupply.com\/products\/seco-74034542-chamfer-milling-tip-0-472-in-carbide-mm12","provider":"Voomi Supply","version":"1.0","type":"link"}
