Built from steel, this single-end modular blade accepts WC, WG, and WR style inserts held by a clamp mechanism. It handles a minimum groove width of 0.1250 inches and a maximum depth of cut of 0.7500 inches, making it a reliable choice for precision internal and external grooving work. The blade is suited for machinists and tooling specialists working in production or job-shop turning environments.\u003c\/p\u003e\n\u003cp\u003eThis blade is applied in grooving and cut-off operations on workpieces ranging from 2.25 inches minimum to 16 inches maximum diameter. It is used in modular tooling systems where quick insert changes and repeatable positioning are required. The left-hand cutting direction suits applications where the spindle rotation or tool approach requires a climb-cut orientation on the workpiece. Compatible insert size code is 3, keeping insert selection straightforward within the WIDIA WC, WG, and WR insert families.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand cutting direction for specific spindle and approach configurations\u003c\/li\u003e\n  \u003cli\u003eModular blade style supports fast insert indexing and system flexibility\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding method provides secure seating under cutting loads\u003c\/li\u003e\n  \u003cli\u003eAccepts WC, WG, and WR insert styles in size code 3\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.7500 inches suits a wide range of groove depths\u003c\/li\u003e\n  \u003cli\u003eSteel blade construction for durability in turning applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with WC, WG, and WR style inserts in insert size code 3.

The blade should be mounted in the appropriate modular toolholder per the tooling system specifications, with the machine powered down and locked out before any tooling changes. Confirm insert seating and clamp torque using the tooling manufacturer's setup guidelines before returning the machine to operation. Verify cutting direction and tool offset registration in the machine control before taking the first cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: WGCRM-B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Style\u003c\/strong\u003e: Modular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Groove Width\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Width\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.7500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Workpiece Diameter\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Workpiece Diameter\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Styles\u003c\/strong\u003e: WC, WG, WR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Size Code\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Insert Width\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Grooving, Cut-Off\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.33 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: WIDIA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6740388\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIDIA","offers":[{"title":"Default Title","offer_id":67909778342194,"sku":"6740388","price":393.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/baf90b1538719cc3535d446cc7e6584f.jpg?v=1791192257","url":"https:\/\/voomisupply.com\/products\/widia-6740388-indexable-grooving-blade-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
