It features a 0.052-inch cutting diameter with a 4-flute, right-hand spiral configuration and a 30-degree helix angle that promotes efficient chip evacuation and smooth cutting action. The bright, uncoated finish makes it suitable for use with cutting fluids in applications where coating could interfere with tolerances. At 1.5 inches overall length with a 1\/8-inch shank, this is a small-diameter tool intended for fine detail work, slotting, and profiling in tight geometries. Micrograin carbide construction delivers the hardness and edge retention needed for demanding materials.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and manual mills used in tool and die, mold making, prototype fabrication, and precision component production. The centercutting geometry allows direct plunge entry as well as conventional peripheral milling. The right-hand cutting direction is standard for most vertical and horizontal spindle setups. It is a single-end tool, meaning it is replaced rather than reground once the cutting edge is worn.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.052-inch cutting diameter with mill diameter tolerance of +0.0000 \/ -0.0010 inches for close-tolerance work\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand spiral flutes at 30-degree helix for balanced chip load and surface finish\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for hardness and edge retention\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge milling without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish compatible with a wide range of cutting fluids and materials\u003c\/li\u003e\n\u003cli\u003e1\/8-inch shank diameter with tolerance of -0.0001 \/ -0.0003 inches for precise collet fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard ER or precision collet systems accepting a 1\/8-inch shank.

Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet to the recommended minimum insertion depth to prevent pullout under load. Verify runout with a dial indicator after tightening, as small-diameter carbide end mills are sensitive to concentricity errors that can cause premature breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.052 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.156 inches (5\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle\/Double End\u003c\/strong\u003e: Single End\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\u003ePackage Weight\u003c\/strong\u003e: 0.25 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: 12276829\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730505761074,"sku":"12276829","price":26.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c049f4815dc5287329bafa5e20521864_033a5891-8eec-446c-9a2c-4779a764cfed.jpg?v=1788718660","url":"https:\/\/voomisupply.com\/products\/accupro-12276829-square-end-mill-0-052-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
