Built from micrograin carbide and coated with TiCN (Titanium Carbonitride), it delivers extended tool life and improved wear resistance compared to uncoated carbide. The 45-degree helix angle promotes aggressive chip evacuation and reduces cutting forces, making it well-suited for harder materials and higher feed rates. With a 1\/2 inch cutting diameter and 1-1\/4 inch length of cut, it handles both roughing and finishing passes in a single-end configuration. Machinists and CNC operators in job shops, aerospace, and general metalworking applications will find this a capable, production-ready tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in vertical and horizontal CNC machining centers as well as manual knee mills where a 1\/2 inch shank can be held in a standard collet or end mill holder. The right-hand cut and right-hand spiral flute direction make it compatible with conventional spindle rotation on most machines. The regular length designation and 3 inch overall length keep the tool rigid, minimizing deflection during side milling, slotting, and profiling operations. It is centercutting, allowing plunge entry directly into the workpiece. No chipbreaker geometry is present, so this tool is optimized for smooth-finish cuts and consistent chip formation in ferrous and non-ferrous metals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-flute geometry increases chip load capacity and improves surface finish on finish-pass cuts\u003c\/li\u003e\n  \u003cli\u003eTiCN coating provides superior hardness and lubricity for extended tool life in steel and stainless applications\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle promotes efficient chip evacuation and reduces heat buildup at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eMicrograin carbide substrate delivers tighter edge integrity and resistance to chipping under interrupted cuts\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and spiral flute direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual mills accepting a 1\/2 inch shank via ER collet, end mill holder, or Weldon-style holder.

Verify spindle and holder cleanliness before seating the shank to prevent runout. Confirm the machine is in a safe, stopped state before inserting or removing the tool. Always follow your facility safety protocols and applicable OSHA machining guidelines when setting feeds, speeds, and depth of cut for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\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: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches (1.25 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: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 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 Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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\u003eWeight\u003c\/strong\u003e: 0.5 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2500053\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728940761394,"sku":"2500053","price":153.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9f9fb16e6c47fe497c6ff7f057227e19.jpg?v=1788697901","url":"https:\/\/voomisupply.com\/products\/accupro-2500053-square-end-mill-1-2-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
