The helical flute geometry promotes smooth chip evacuation and reduces cutting forces during reaming operations. This head measures 20.00 mm in diameter with a head length of 0.409 inches and carries an h7 hole tolerance rating, making it suitable for applications requiring tight dimensional control. A bright coating is applied to the cutting surfaces. The left-hand cutting direction suits specific spindle configurations and fixturing setups encountered in aerospace and high-temp alloy machining environments. Machinists and tooling technicians working on precision boring and finishing operations are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis modular reamer head is used in CNC machining centers and boring mills where modular tooling systems allow quick head changes without disturbing the full tool assembly. It is particularly suited for finishing bores in high temperature alloys such as those common in aerospace, power generation, and industrial turbine component manufacturing. The h7 tolerance class targets interference and transition fit bore applications where dimensional accuracy is critical. The left-hand cut configuration is selected when workpiece rotation or fixturing requires non-standard cutting direction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHelical flute geometry supports efficient chip evacuation in difficult-to-machine alloys\u003c\/li\u003e\n  \u003cli\u003e20.00 mm head diameter with h7 hole tolerance for precision bore finishing\u003c\/li\u003e\n  \u003cli\u003eLeft-hand cutting direction for specialized spindle and fixturing requirements\u003c\/li\u003e\n  \u003cli\u003eBright coating applied to cutting surfaces\u003c\/li\u003e\n  \u003cli\u003eModular design enables head replacement without removing the full tool from the holder\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 tooling data standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with modular reamer systems accepting a 20.00 mm head diameter in left-hand cut configuration.

Ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer head. Confirm the mating shank interface is clean and free of chips or burrs before seating the head to achieve proper torque transfer and runout performance. Follow the tooling manufacturer assembly torque guidelines for the specific modular interface being used.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 20.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 0.409 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Tolerance\u003c\/strong\u003e: h7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: High Temperature Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 0.91 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 2.09 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 2.24 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.099 pounds\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5100030\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51737529483570,"sku":"5100030","price":409.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b39a19c737db35a89a07e23a0bf621b.jpg?v=1788789852","url":"https:\/\/voomisupply.com\/products\/iscar-5100030-modular-reamer-head-helical-flute-20mm","provider":"Voomi Supply","version":"1.0","type":"link"}
