Built from micrograin carbide stock and finished with an nACRo coating, it delivers hardness and heat resistance suited for ferrous and non-ferrous materials. The mill measures 0.2031 inches in diameter with a 5\/8 inch length of cut and a 1\/4 inch shank. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. With 2 spiral flutes and a centercutting design, it handles both plunge and side milling operations. Licensed machinists and CNC operators working in job shops, tool rooms, and production environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard milling machines, CNC machining centers, and manual knee mills equipped with a 1\/4 inch collet or end mill holder. It is suited for finish and semi-finish passes on steel, stainless, aluminum, and similar materials where close-tolerance profiling or slotting is required. The right-hand cut and right-hand spiral flute configuration is the industry-standard orientation for conventional and climb milling setups. Overall length of 2-1\/2 inches keeps deflection low in tight-reach applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003enACRo finish coating for improved tool life in demanding cut conditions\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard CNC and manual mill setups\u003c\/li\u003e\n\u003cli\u003eTight diameter tolerance of +0.000 \/ -0.002 inches for precise fit and finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any milling machine or machining center accepting a 1\/4 inch shank end mill holder or collet.

Power down and lock out the spindle before loading or removing the tool from the holder. Seat the shank to the minimum insertion depth recommended for the collet or end mill holder in use. Inspect the collet bore and tool shank for chips or debris before tightening, as contamination affects runout and tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 13\/64 inch (0.2031 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eFinish Coating\u003c\/strong\u003e: nACRo\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: +0.000 \/ -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: 0.25 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: 12178748\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732398604594,"sku":"12178748","price":51.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5e0db57dc016c6453b0eb12067c5293_abd9d971-b109-4c59-997d-66a89e1fcb6b.jpg?v=1788742401","url":"https:\/\/voomisupply.com\/products\/accupro-12178748-square-end-mill-13-64-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
