It features a 1\/4 inch cutting diameter with a 1 inch length of cut, a 38-degree helix angle, and a Variable Index geometry that reduces chatter and improves surface finish. The AlTiCrN coating provides heat resistance and extended tool life in ferrous and hardened materials. This is a single-end, center-cutting tool built for right-hand cutting with right-hand spiral flutes. It is used by machinists and tool-and-die professionals on CNC machining centers and manual knee mills.\u003c\/p\u003e\u003cp\u003eThe 310125 is suited for slotting, profiling, and peripheral milling in steel, stainless steel, and high-temperature alloys where coating performance and edge stability matter. The micrograin carbide substrate supports sharper edges and tighter tolerances compared to standard carbide grades. With a 1\/4 inch shank diameter matching the cutting diameter and a 3 inch overall length, this tool fits standard 1\/4 inch collets and end mill holders commonly found in both production and job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4 inch cutting diameter with 1 inch length of cut for shallow-to-moderate depth passes\u003c\/li\u003e\n\u003cli\u003e4 flute, right-hand spiral configuration for efficient chip evacuation and finish quality\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle reduces cutting forces and vibration\u003c\/li\u003e\n\u003cli\u003eVariable Index flute spacing minimizes harmonic chatter during aggressive cuts\u003c\/li\u003e\n\u003cli\u003eAlTiCrN coating delivers thermal and oxidation resistance in dry or near-dry machining\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for superior edge retention and dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable — suitable for plunge entry and ramping operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/4 inch collets and end mill holders on CNC machining centers and manual milling machines.

Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in the collet or holder to the recommended gauge length and torque the retention mechanism per the tool holder manufacturer specification. Inspect the cutting edges for chips or coating damage before use and verify runout with a dial indicator before beginning a new operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.250 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.250 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.000 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3 inches\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: 38 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End, Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiCrN\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\u003eSeries\u003c\/strong\u003e: HS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 310125\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734734045490,"sku":"310125","price":67.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eba10b8bc807373834f5982c01829f92.jpg?v=1788766311","url":"https:\/\/voomisupply.com\/products\/accupro-310125-square-end-mill-1-4-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
