It measures 0.125 inches in diameter with a 0.125-inch length of cut and a 1.5-inch overall length. The cutting geometry features 4 flutes with a variable flute type, a 35-degree helix angle, and a 45-degree chamfer angle at 0.01 inches chamfer width. A TiAlN PVD coating provides thermal resistance and extends tool life in high-speed cutting environments. The straight-cylindrical shank measures 0.125 inches in diameter with an h6 tolerance, ensuring consistent runout in standard collet systems. This tool is suited for machinists and toolroom professionals working on steel, stainless steel, cast iron, superalloys, titanium, and hard materials.\u003c\/p\u003e\n\u003cp\u003eThe VG436-1252 is built for both roughing and finishing operations in a single-end stub-length configuration. Its centercutting capability allows direct plunge entry, making it practical for slotting passes as well as chamfer blending on part edges. The variable index geometry helps reduce harmonic chatter during interrupted cuts or when working harder alloy grades. Primary workpiece material categories include steel (P), stainless steel (M), cast iron (K), superalloys and titanium (S), and hard materials (H). Secondary workpiece suitability is rated for hard materials (H). The right-hand flute direction and right-hand cutting orientation match standard spindle configurations on most CNC machining centers and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous and hard-material cutting\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating for elevated thermal performance and extended tool life at higher surface speeds\u003c\/li\u003e\n  \u003cli\u003e45-degree chamfer angle with 0.01-inch chamfer width for consistent edge preparation\u003c\/li\u003e\n  \u003cli\u003eVariable index flute geometry reduces chatter and vibration during aggressive passes\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry for slotting and pocket entry\u003c\/li\u003e\n  \u003cli\u003e35-degree medium helix balances chip evacuation and cutting edge strength across material classes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use on steel, stainless steel, cast iron, superalloys, titanium, and hard materials.

Secure the shank in a precision collet or end mill holder rated for the shank diameter and verify runout before cutting. Confirm spindle speed and feed rate are appropriate for the workpiece material and tool diameter before engaging the cut. Do not exceed the rated length of cut of 0.125 inches to avoid deflection or premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.01 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0015 inches\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: Variable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VG436\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: VG436-1252\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728343925042,"sku":"VG436-1252","price":32.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/230d644f0e06f04908fe49494e071508.jpg?v=1788690561","url":"https:\/\/voomisupply.com\/products\/osg-vg436-1252-corner-chamfer-end-mill-1-8-inch-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
