It features a spiral flute geometry with a left-hand spiral direction and right-hand cutting direction, producing a clean, accurate bore on the down-stroke. The reamer measures 0.0938 inches (3\/32 inch) in diameter with a total overall length of 1.9685 inches and an 11 mm flute length. With 4 flutes and a bright, uncoated finish, this tool delivers consistent sizing performance in tight-tolerance bores. It is suited for use in CNC machining centers, manual mills, and drill presses where repeatable hole diameter control is required.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is intended for finish reaming operations in ferrous and non-ferrous metals where precise hole tolerances are critical. The straight cylindrical shank allows direct mounting in standard collet chucks, drill chucks, or machine tool holders. At 3\/32 inch diameter, it is well suited for small-bore work in precision components, tooling fixtures, and close-tolerance assemblies. A licensed machinist or CNC operator would typically deploy this tool as a final-pass reamer following a drilled or bored pilot hole.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cutting conditions\u003c\/li\u003e\n  \u003cli\u003eLeft-hand spiral flute geometry with right-hand cutting direction for clean chip evacuation on the down-stroke\u003c\/li\u003e\n  \u003cli\u003e4-flute design provides excellent surface finish and accurate hole sizing\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for general-purpose machining without coating-related dimensional offset\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of 0.0000 to +0.0003 mm for tight, consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard collet and drill chuck holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style chucking reamer for use in CNC machining centers, knee mills, and drill presses equipped with standard straight-shank collet or drill chuck toolholders accepting a 3\/32 inch diameter shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer from the toolholder. Always run a pilot hole to the appropriate pre-ream diameter before deploying a chucking reamer to avoid tool deflection or breakage. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 3\/32 inch (0.0938 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.9685 inches (50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Direction\u003c\/strong\u003e: 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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter 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  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MR34-0937.438\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51736235639090,"sku":"MR34-0937.438","price":276.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b73be95767e6ed702793bb8a45069ce7.jpg?v=1788776670","url":"https:\/\/voomisupply.com\/products\/hertel-mr34-0937-438-chucking-reamer-3-32-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
