It is manufactured from powdered metal and finished with a TiCN (Titanium Carbonitride) coating, which improves surface hardness and heat resistance compared to uncoated tooling. The 1 inch cutting diameter, 4 inch length of cut, and 3-flute spiral geometry make it well suited for slotting, profiling, and peripheral milling where chip evacuation and cut quality are priorities. The 42-degree helix angle promotes smooth cutting action and reduced chatter. This tool is centercutting, allowing it to plunge directly into the workpiece.\u003c\/p\u003e\u003cp\u003eThis end mill is used in vertical and horizontal machining centers, CNC mills, and manual knee mills across job shops, tool rooms, and production environments. Its 1 inch shank diameter fits standard R8, CAT, BT, and HSK toolholders with a 1 inch bore. The 6.5 inch overall length provides reach for deeper setups where a standard-length tool would not clear the fixture. Right-hand cut and right-hand flute orientation are standard for conventional and climb milling on most CNC and manual spindles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiCN coating provides increased surface hardness and heat resistance for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e42-degree helix angle reduces cutting forces and chatter in longer-reach applications\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003e3-flute spiral geometry balances chip clearing with rigidity for a 1 inch diameter tool\u003c\/li\u003e\n\u003cli\u003ePowdered metal substrate offers a fine-grain structure for a sharp, consistent cutting edge\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for compatibility with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct substitute for standard 1 inch diameter, 3-flute square end mills with a 1 inch shank.

Ensure the spindle is fully powered down and locked before inserting or removing the tool from the holder. Verify holder bore cleanliness and shank runout with a dial indicator before cutting to avoid premature edge wear. Follow shop-specific feeds, speeds, and depth-of-cut parameters for the workpiece material and machine rigidity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0015 \/ -0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 42 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: TiCN\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle End\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: ED99921234\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728445112626,"sku":"ED99921234","price":277.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e8472edb7e6f034de2174e998abc55c_2b540a3c-8c5e-4c0c-9aa6-b8e17b7ba605.jpg?v=1788691299","url":"https:\/\/voomisupply.com\/products\/accupro-ed99921234-square-end-mill-1-in-3-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
