With a 0.25-inch mill diameter, a 0.75-inch length of cut, and a TiCN coating, this tool delivers consistent performance when cutting high-temperature alloys, stainless steel, and steel. The micrograin carbide substrate supports edge retention at elevated cutting speeds, and the 40-degree helix angle promotes efficient chip evacuation. Right-hand cut and right-hand flute geometry are standard for conventional milling setups. Licensed machinists and tool-and-die professionals are the primary users of this end mill.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slot milling, peripheral milling, and profiling in ferrous and high-temperature alloy materials. The 0.25-inch shank fits standard 1\/4-inch collets and end-mill holders on vertical machining centers and manual knee mills. With a 2.5-inch overall length and a regular-length classification, it handles typical depth requirements without the deflection risk of extended-reach tooling. Primary target materials include high-temperature alloys, stainless steel, and general-purpose steel. It is not center-cutting, so it is not suited for direct plunge operations without pre-drilling or ramping entry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for edge retention in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eTiCN finish improves surface hardness and lubricity, extending tool life in stainless and high-temp alloys\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e4-flute configuration balances material removal rate with chip clearance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute geometry for standard CNC and manual mill setups\u003c\/li\u003e\n  \u003cli\u003eNot center-cutting  -  ramp or helical entry required for plunge starts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 1\/4-inch collets and end-mill holders on vertical machining centers and manual milling machines.

Secure the shank fully into a clean, properly sized collet or end-mill holder to the recommended engagement depth before tightening. Ensure the spindle and machine table are powered down and at a complete stop before changing tooling. Verify runout with a dial indicator after installation to confirm concentricity before cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 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\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eFinish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: High Temperature Alloy, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 111\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: PROMAX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 111-01612\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":51999086248242,"sku":"111-01612","price":67.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe2c325b4a98a6311a1ccfd959fc74e2.jpg?v=1789995299","url":"https:\/\/voomisupply.com\/products\/promax-111-01612-square-end-mill-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
