Built from micrograin solid carbide and finished with an AlTiN coating, this tool delivers thermal resistance and hardness retention at elevated cutting temperatures. It runs a 4-flute, right-hand spiral configuration with a 40-degree helix angle, balancing chip evacuation with surface finish quality. With a 1 inch cutting diameter and 1.75 inch length of cut, it suits deep-pocket, contour, and 3D profiling work. Machinists and CNC programmers select this tool for high-speed and hard-material applications where tool life and dimensional accuracy are priorities.\u003c\/p\u003e\u003cp\u003eThe 12177137 is suited for CNC machining centers running ferrous alloys, stainless steels, titanium, and other abrasion-intensive workpiece materials where AlTiN coating performance is advantageous. The 1 inch shank diameter fits standard ER and end mill holders in that bore size. Its 4 inch overall length provides reach for moderate-depth features without excessive tool deflection. This tool is appropriate for job shops, aerospace component machining, and die and mold work where consistent tool geometry is required across a production run.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides oxidation resistance and extends tool life at high cutting temperatures\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle balances chip flow and cutting edge stability\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand spiral geometry optimized for finish milling and contouring\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with matched 1 inch shank and cutting diameter for direct holder compatibility\u003c\/li\u003e\n\u003cli\u003eNo extended reach, variable helix, or variable index — consistent, predictable cutting geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for CNC machining applications requiring a 1 inch diameter ball end mill with a 1 inch shank in AlTiN-coated solid carbide.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup personnel. Secure the shank in a properly sized end mill holder or collet chuck and torque to the holder manufacturer's specification. Verify runout with a dial indicator before cutting. Always confirm spindle direction matches the right-hand cutting orientation of this tool before starting the machine.\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\u003eLength of Cut\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 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: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eWeight\u003c\/strong\u003e: 1.342 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: 12177137\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51750544965938,"sku":"12177137","price":652.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e223dbcb9734255700dd1787213a94d5.jpg?v=1788916454","url":"https:\/\/voomisupply.com\/products\/accupro-12177137-ball-end-mill-1-in-4-flute-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
