Built from powdered metal with a TiCN (titanium carbonitride) finish, it delivers good wear resistance and thermal hardness at an accessible price point compared to solid carbide tooling. The cutter measures 1 inch in diameter with a 3-inch length of cut, a 1-inch shank diameter, and a 5-1\/2-inch overall length. Three spiral flutes at a 42-degree helix angle promote chip evacuation and reduce chatter during aggressive cuts. Centercutting geometry allows plunge entry directly into the workpiece.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for general-purpose peripheral milling, slotting, and plunge operations on ferrous and non-ferrous workpiece materials in both job-shop and production environments. The right-hand cut and right-hand flute orientation match standard spindle rotation on the vast majority of vertical machining centers and manual knee mills. The 42-degree helix angle makes it a practical choice for finishing passes and medium-chip-load roughing where tool deflection must be managed on longer reaches.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePowdered metal construction with TiCN finish for improved wear resistance over high-speed steel\u003c\/li\u003e\n  \u003cli\u003e42-degree helix spiral flute for aggressive chip evacuation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eThree flutes balance chip clearance and surface finish across a wide range of feed rates\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute — compatible with standard CNC and manual spindle setups\u003c\/li\u003e\n  \u003cli\u003e1-inch shank diameter with tight shank tolerance (-0.0001 \/ -0.0005 inches) for secure tool-holder engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use cutting tool for CNC vertical machining centers and manual mills accepting a 1-inch straight shank.

Power down and lock out the machine spindle before seating or removing the tool from the holder. Use a calibrated torque wrench on set-screws or draw bolts per the tool-holder manufacturer specifications — do not over-torque. Verify runout with a dial indicator after securing the tool; excessive runout shortens tool life and degrades surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\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 \/ Coating\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0015 \/ -0.0000 inches\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\u003eExtended Reach\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ED99921232\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727220375858,"sku":"ED99921232","price":288.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e8472edb7e6f034de2174e998abc55c.jpg?v=1788674896","url":"https:\/\/voomisupply.com\/products\/accupro-ed99921232-square-end-mill-1-in-3-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
