Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention when cutting steel, stainless steel, cast iron, and high-temperature alloys. The mill features a 0.75-inch cutting diameter, a 1.3125-inch length of cut, and a 30-degree helix angle on a spiral flute geometry. The bright, uncoated finish suits shops that re-sharpen tooling or apply their own coatings. This is a short-length tool intended for rigid setups where minimizing deflection is a priority. Machinists and tool-and-die professionals are the primary users.\u003c\/p\u003e\n\u003cp\u003eThe 17011652 fits vertical and horizontal milling machines, CNC machining centers, and manual knee mills where a 0.5-inch shank is accepted. Its 3.3125-inch overall length keeps the tool compact for short-reach slotting, profiling, and peripheral milling. The right-hand cut and right-hand flute configuration matches the standard spindle rotation of most machining center setups. With centercutting capability, the tool can plunge directly into a workpiece without a pre-drilled entry hole. The two-flute configuration provides good chip clearance when working in softer steel grades and materials with gummy chip characteristics.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for elevated heat resistance in interrupted cuts and hard materials\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth chip evacuation on spiral flute geometry\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — compatible with re-sharpening and custom coating processes\u003c\/li\u003e\n  \u003cli\u003eTwo-flute layout maximizes chip pocket volume for improved clearance in steel and stainless\u003c\/li\u003e\n  \u003cli\u003eShort-length classification supports rigid setups and reduces chatter in tight work envelopes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the SECO SP205 series. Rated for primary use in steel, stainless steel, cast iron, and high-temperature alloys (material codes P, M, K, S). Accepts standard 0.5-inch collet chucks, end mill holders, and hydraulic toolholders configured for a 0.5-inch shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom personnel following standard toolholder torque and runout procedures for the specific holder in use. Verify spindle stop and machine lockout before changing tooling. Seat the shank fully into the holder and confirm TIR does not exceed 0.001 inches before cutting. Do not exceed the tool's rated depth of cut per pass for the workpiece material being machined.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches (3\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.3125 inches (1-5\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.3125 inches (3-5\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 grade)\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0030 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0620 \/ 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SP205\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\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\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17011652\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560986640690,"sku":"17011652","price":76.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/686dc3695ff3f36c37307c60b1cee92c_56f1a1f1-3604-4585-978c-f2f31d16a47b.jpg?v=1786460654","url":"https:\/\/voomisupply.com\/products\/seco-17011652-square-end-mill-3-4-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
