Built from high speed steel with an uncoated finish, this tool features a 0.125-inch mill diameter, a 0.375-inch length of cut, and a 30-degree right-hand spiral helix. The 2-flute geometry promotes chip evacuation and suits contour milling, profiling, and slotting passes where a ball-nose profile is required. With an overall length of 2.3125 inches and a 0.375-inch shank diameter, it fits standard end mill holders and collet chucks in vertical mills and machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for finishing passes on cast iron and steel components in job shop, tool-and-die, and general machining environments. The HG-2B series is a regular-length, single-end configuration intended for applications where tool reach is not the primary constraint and surface finish is the priority. It is appropriate for use in both manual knee mills and CNC vertical machining centers where a small-diameter ball nose profile is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.125-inch ball nose diameter for fine detail and contour finishing\u003c\/li\u003e\n  \u003cli\u003e2-flute spiral design promotes chip clearance on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand helix for smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides toughness across a range of steels\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — compatible with standard cutting fluids and lubricants\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with 0.375-inch shank for broad holder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on primary workpiece materials including cast iron and steel.

Ensure the shank is fully seated and the holder drawbar or collet nut is torqued per the holder manufacturer specifications. Verify runout with a dial indicator after clamping before beginning any cut. Select feeds, speeds, and depth of cut according to the workpiece material and machine rigidity — do not exceed the rated length of cut of 0.375 inches axially.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HG-2B\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\u003eChipbreaker\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\u003eVariable Index\u003c\/strong\u003e: No\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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C42109\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51698137989426,"sku":"C42109","price":64.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/af7e0cb9699137f8473829118aa4479c.jpg?v=1788358310","url":"https:\/\/voomisupply.com\/products\/cleveland-c42109-ball-end-mill-0-125-in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
