With a reamer diameter of 0.0118 inches (0.30 mm) and an overall length of 1.9685 inches (50.00 mm), this tool is built for micro-bore work where dimensional accuracy is critical. The four-flute, left-hand spiral geometry with right-hand cutting direction promotes smooth chip evacuation and reduces chatter in small-diameter bores. A bright polished finish minimizes friction and helps maintain bore surface quality. Machinists and tool-room professionals rely on tools like this for reaming precision holes in hardened or difficult-to-machine materials.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is suited for use in CNC machining centers, drill presses, and manual lathes where precise bore sizing is required. The straight shank allows direct mounting in standard collet chucks or drill chucks. With a flute length of 2.00 mm (approximately 0.079 inches), this tool targets very shallow bore finishing operations. It is appropriate for production environments and tool-room setups working with micro-diameter holes in metals, composites, or plastics.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in micro-bore applications\u003c\/li\u003e\n\u003cli\u003eFour left-hand spiral flutes with right-hand cutting direction for smooth chip flow\u003c\/li\u003e\n\u003cli\u003eReamer diameter tolerance of 0.0000 to +0.0003 mm for tight bore control\u003c\/li\u003e\n\u003cli\u003eBright polished coating reduces friction and aids surface finish quality\u003c\/li\u003e\n\u003cli\u003eStraight shank for direct mounting in collet or drill chucks\u003c\/li\u003e\n\u003cli\u003eCompact 1.9685-inch overall length suited for confined machining setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style chucking reamer for use in standard straight-shank collet systems and drill chuck setups requiring a 0.0118-inch diameter bore finish tool.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists familiar with precision reaming operations. Ensure the machine spindle and chuck are free of runout before mounting to preserve diameter tolerance. Always bring the workpiece to correct pre-reamed size before using this tool, as chucking reamers remove only a small amount of material. Follow applicable shop safety practices and machine manufacturer guidelines when operating at high spindle speeds with micro-diameter tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.0118 inches (0.30 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.9685 inches (50.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.00 mm\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: Spiral, Left Hand\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: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright (Polished)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter Tolerance\u003c\/strong\u003e: 0.0000 to +0.0003 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MR34-0118.079\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728311877938,"sku":"MR34-0118.079","price":123.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/520f5bf697a060d000f30d00528e7c97_2b5379fc-b251-41ab-95e8-7c1c247b5d76.jpg?v=1788690402","url":"https:\/\/voomisupply.com\/products\/hertel-mr34-0118-079-chucking-reamer-0-0118-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
