With a reamer diameter of 0.0126 inches (0.32 mm) and a diameter tolerance of 0.0000 to +0.0003 mm, this tool delivers consistent, accurate sizing in small-bore work. The bright polished finish reduces friction and aids chip evacuation. At 1.9685 inches overall length with a 0.1575-inch flute length, it is suited for use in CNC machining centers, drill presses, and precision lathes. Machinists and tool-and-die professionals working in high-precision environments rely on this type of reamer for final bore sizing after drilling.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is intended for small-diameter precision reaming operations where tight dimensional control is required. The straight shank allows direct mounting in standard collet chucks or drill chucks on machining equipment. With 4 flutes and a left-hand spiral combined with right-hand cutting direction, chip flow is controlled to minimize surface damage in blind and through holes. It is well suited for metals and other materials where bore finish and diameter accuracy are critical to assembly fit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for hardness, wear resistance, and dimensional stability\u003c\/li\u003e\n\u003cli\u003e0.0126 inches (0.32 mm) diameter with tolerance of 0.0000 to +0.0003 mm for precision fitment\u003c\/li\u003e\n\u003cli\u003e4-flute left-hand spiral geometry with right-hand cutting direction for controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright polished finish reduces friction and improves surface finish in reamed bores\u003c\/li\u003e\n\u003cli\u003eStraight shank compatible with standard collet and drill chuck holders\u003c\/li\u003e\n\u003cli\u003e1.9685 inches overall length suits compact workholding setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style precision chucking reamer for use in standard straight-shank collet systems and drill chucks on CNC machining centers, drill presses, and precision lathes requiring small-diameter bore finishing.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists familiar with precision reaming procedures. Ensure the machine spindle and workholding are fully stopped and de-energized before mounting or removing the tool. Use appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish. Do not use this reamer as a drilling tool; always pre-drill or bore the hole to near-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: 0.0126 inches (0.32 mm)\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\u003eOverall Length\u003c\/strong\u003e: 1.9685 inches (50.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.1575 inches (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\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\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 (Polished)\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: MR34-0126.079\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747148398898,"sku":"MR34-0126.079","price":123.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/441c9bb57548a35041d43466421234d4.jpg?v=1788876750","url":"https:\/\/voomisupply.com\/products\/hertel-mr34-0126-079-chucking-reamer-0-0126-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
