Built with four straight flutes and a right-hand cutting direction, it delivers a smooth, accurate bore finish in a single pass. The straight-cylindrical shank seats securely in a drill chuck or collet for reliable concentricity. With an overall length of 3.5 inches and a flute length of 0.875 inches, this reamer suits tight-clearance applications where controlled material removal and hole-size accuracy are critical. Machinists, tool-and-die workers, and maintenance technicians use this tool in both manual and CNC setups.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is suited for finish-reaming small-diameter holes in metal components across general machining, maintenance, and repair operations. The 0.1215-inch diameter falls within the 0.1000 to 0.1499 inch reamer diameter range and is appropriate for production or jobsite work where close-tolerance hole sizing is required. It is sold individually with a minimum order quantity of one unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePrecision diameter of 0.1215 inches for tight-tolerance finish reaming\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction provides wear resistance across common workpiece materials\u003c\/li\u003e\n\u003cli\u003eFour straight flutes with right-hand cutting direction for smooth material removal\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for general-purpose machining applications\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for secure seating in standard drill chucks or collets\u003c\/li\u003e\n\u003cli\u003eCompact overall length of 3.5 inches with a flute length of 0.875 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose chucking reamer compatible with standard drill chucks and collet holders accepting a straight-cylindrical shank in the 0.1000 to 0.1499 inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers are installed by machinists using a drill press, lathe, or CNC machining center. Ensure the workpiece is securely fixtured and the machine spindle is powered down before mounting or removing the tool. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not use a chucking reamer to remove excessive stock — pre-drill or bore the hole to within a few thousandths of final size before reaming.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.1215 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Range\u003c\/strong\u003e: 0.1000 to 0.1499 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: HSS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDowel Pin Reamer\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOver\/Under Size Reamer\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 72012156\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727317074226,"sku":"72012156","price":56.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a40272d09b39da88529778c4e9675c6b_5ad1ce76-b976-4972-987c-f7f1c5cda4e1.jpg?v=1788676243","url":"https:\/\/voomisupply.com\/products\/hertel-72012156-chucking-reamer-0-1215-in-hss-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
