Built from M42 cobalt high-speed steel and coated with TiCN for elevated heat and wear resistance, it delivers reliable performance in demanding milling operations. The 1.25 inch diameter, 6-flute configuration with a 30-degree helix angle promotes efficient chip evacuation while maintaining a rigid cutting profile. With a 2-inch length of cut and 4.5-inch overall length, this is a short-series tool suited for setups where overhang and deflection must be minimized. Installation and operation require a standard end mill holder or collet chuck compatible with a 1.25 inch shank.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is intended for use in CNC milling machines and manual knee mills where stock removal rates matter. The TiCN coating and M42 substrate make it well suited for cutting steel, stainless steel, and high-temp alloys. The right-hand cut and right-hand spiral flute direction follow standard industry convention. It is a short-series tool, making it a practical choice when machining pockets, slots, or profiles where clearance is limited. No coolant-through capability means it relies on flood, mist, or air-blast coolant delivered externally.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt high-speed steel substrate for toughness in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves surface hardness and reduces heat buildup at the cutting edge\u003c\/li\u003e\n\u003cli\u003e6-flute design increases feed rate potential while roughing\u003c\/li\u003e\n\u003cli\u003e30-degree maximum helix angle supports chip flow in deeper cuts\u003c\/li\u003e\n\u003cli\u003eShort-series length reduces deflection and improves rigidity during heavy passes\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral — compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any milling machine spindle or toolholder accepting a 1.25 inch straight shank end mill.

Power down and lock out the machine spindle before installing or removing the tool. Seat the shank fully into the holder and torque the drawbar or set screws to the toolholder manufacturer's specification. Inspect the cutting edges for chips or wear before each use, as a damaged edge on a roughing tool can cause tool pull-out or workpiece damage under load.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.006 to -0.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.062 to -0.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: REM445\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17016215\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560255488306,"sku":"17016215","price":234.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc02fbdd14cb29a2ef9705c81c46f6d9_adb1037b-eb31-4aeb-bc33-5421a3bb2399.jpg?v=1786449717","url":"https:\/\/voomisupply.com\/products\/seco-17016215-roughing-end-mill-1-1-4-in-6-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
