Built from micrograin solid carbide and coated with AlTiN, it is engineered to run at elevated temperatures and maintain cutting-edge integrity in hardened materials and steel. The 6-flute geometry combined with a 45-degree helix angle promotes smooth chip evacuation and reduced vibration. With a 0.1875-inch cutting diameter, 0.5-inch length of cut, and 3-inch overall length, this end mill fits standard toolholders used in CNC milling centers across job shops and production environments. It is center-cutting and uses a right-hand cut with right-hand flute spiral.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for finish and semi-finish milling of hardened steels and ferrous alloys where tool life and dimensional accuracy are critical. The AlTiN coating provides oxidation resistance and thermal hardness, making it appropriate for dry or minimal-lubrication cutting strategies. The Series MZ645 designation places it within SECO's line of carbide end mills optimized for ISO P and ISO H workpiece material groups. A straight-cylindrical shank with 0.25-inch diameter provides secure clamping in collet chucks, end mill holders, and hydraulic toolholders commonly used in precision machining setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for rigidity and wear resistance in hardened materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides high thermal resistance suitable for dry and hard milling\u003c\/li\u003e\n  \u003cli\u003e6-flute configuration increases feed rates and improves surface finish\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle reduces cutting forces and vibration\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows plunge entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flute with straight-cylindrical shank for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for machining hardened materials and steel (ISO material groups H and P).

Before mounting, confirm toolholder runout does not exceed the maximum TIR specification to protect cutting-edge integrity. Secure the straight-cylindrical shank fully within the toolholder to the recommended gauge-line depth before tightening. Verify spindle direction and programmed feed and speed parameters are appropriate for the workpiece material before initiating the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hardened Materials, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MZ645\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0600 \/ -0.0600 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 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: 17004771\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557422301490,"sku":"17004771","price":201.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aad808e64d0a260b2fe9451df670f1e7_81acde7f-634b-4132-852c-a8fd6662f006.jpg?v=1786387704","url":"https:\/\/voomisupply.com\/products\/seco-17004771-square-end-mill-3-16-in-6-flute-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
