It features a CVD-applied aluminum oxide (Al2O3) coating finish designed to extend tool life on challenging workpieces. The cutting width is 0.1575 inches with a corner radius of 1\/128 inch and an 8-degree right-hand lead angle. This insert is sized as a WCF size 4 and is held in the toolholder by a clamp-style retention method. It is intended for use by machinists and CNC lathe operators performing cutoff, grooving, and chamfering operations.\u003c\/p\u003e\u003cp\u003eThe 1GRB006 is suited for turning applications on stainless steel and steel workpieces, corresponding to ISO material groups M and P. The AC830P grade with CVD Al2O3 coating provides wear resistance for continuous and interrupted cuts in these material classes. This insert is a single-use, non-multi-use geometry and is sold individually. It is a direct fit for toolholders designed around the WCF insert series and clamp-style insert retention systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with CVD-applied Al2O3 coating for wear resistance on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003e0.1575 inch cutting width for precise cutoff and grooving operations\u003c\/li\u003e\n\u003cli\u003e8-degree right-hand lead angle with right-hand insert orientation\u003c\/li\u003e\n\u003cli\u003e1\/128 inch corner radius for controlled groove geometry\u003c\/li\u003e\n\u003cli\u003eCompatible with chamfering, cut-off, and grooving applications in a single insert geometry\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding for secure, repeatable seating in WCF toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in clamp-style toolholders built around the WCF insert series.

Shut down the machine and lock out spindle power before changing inserts. Seat the insert fully into the toolholder pocket before tightening the clamp to manufacturer torque specifications for the holder. Inspect the clamp and pocket for chips or debris before seating a fresh insert to prevent micro-fracture at the cutting edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: WCF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: WCF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC830P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Finish\u003c\/strong\u003e: Al2O3 (Coated)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.1575 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/128 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 8 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Chamfering, Cut-off, Grooving\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: M, P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C5A, C6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-use Tool\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SUMITOMO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1GRB006\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51730537283890,"sku":"1GRB006","price":31.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_04e6f0d3-9948-45af-ac3e-4d9ff35c8d92.jpg?v=1788719183","url":"https:\/\/voomisupply.com\/products\/sumitomo-1grb006-carbide-cutoff-insert-ac830p","provider":"Voomi Supply","version":"1.0","type":"link"}
