It features a 3\/8 inch cutting diameter, a 1-1\/8 inch length of cut, and a 3-1\/4 inch overall length. The 7-flute geometry with a variable helix angle of 37 degrees reduces harmonic vibration and improves surface finish at higher feed rates. A TiN finish provides added surface hardness and lubricity. This tool is installed and operated by machinists and CNC operators working in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThe SGS 77151 belongs to the Series 77 long-reach end mill family and is suited for slotting, profiling, and peripheral milling in a range of metallic and non-metallic workpiece materials. Its chipbreaker geometry helps manage chip evacuation during deeper cuts. The straight-cylindrical shank with h6 tolerance fits standard ER collets and end mill holders without modification. It is appropriate for applications requiring extended reach beyond what standard-length end mills can provide.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7-flute variable helix design at 37 degrees reduces chatter and improves surface finish\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction provides rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiN finish increases surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003eChipbreaker geometry aids chip evacuation in deep slotting and profiling operations\u003c\/li\u003e\n\u003cli\u003eLong series length with 1-1\/8 inch LOC supports extended reach applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral flute configuration compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with workpiece material codes H, K, M, N, P, and S, covering cast iron, non-ferrous metals, stainless steel, non-metals, steel, and high-temperature alloys.

Ensure the machine spindle is fully stopped and the tool changer or collet is de-energized before seating or removing the end mill. Verify collet or holder bore cleanliness and confirm proper stick-out length before tightening to the tool holder specification. Do not exceed the tool manufacturer's recommended depth-of-cut or feed-per-tooth values for the workpiece material being machined.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\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\u003eFinish\u003c\/strong\u003e: TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.062 \/ -0.062 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 77\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.38 x 0.55 x 0.55 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: SGS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 77151\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51750561972530,"sku":"77151","price":144.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f2ce39e0ca3a1483bc4b501a5b888ef7_c991a90a-16a9-46d1-bb31-3c18047b1b1c.jpg?v=1788916725","url":"https:\/\/voomisupply.com\/products\/sgs-77151-square-end-mill-3-8-in-7-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
