It uses a screw clamp insert-holding method to secure TC-style trigon inserts with a 1\/4-inch inscribed circle. The toolholder features a neutral rake angle of 0 degrees and a right-hand cutting orientation. The steel shank measures 3\/8 inch wide by 3\/8 inch tall and has an overall length of 2.5 inches. This toolholder is used by machinists and tool-and-die professionals requiring consistent insert positioning and rigid clamping in tight-clearance turning applications.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is suited for light-duty external turning where a compact 3\/8-inch shank is required. The STGCR configuration accommodates neutral-rake trigon inserts, making it appropriate for general-purpose turning of ferrous and non-ferrous workpieces. The back-of-bar to cutting edge distance is 0.5 inches, allowing effective tool positioning in standard tool posts and quick-change tooling systems. It is well matched to smaller lathes and Swiss-style setups where shank clearance is limited.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSTGCR toolholder style with right-hand cutting orientation\u003c\/li\u003e\n  \u003cli\u003eScrew clamp insert-holding method for positive, repeatable insert location\u003c\/li\u003e\n  \u003cli\u003eCompatible with TC-style trigon inserts, 1\/4-inch inscribed circle\u003c\/li\u003e\n  \u003cli\u003eNeutral rake angle (0 degrees) for versatile turning applications\u003c\/li\u003e\n  \u003cli\u003eSteel construction for rigidity and durability under cutting loads\u003c\/li\u003e\n  \u003cli\u003eCompact 2.5-inch overall length suits tight-clearance tool posts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with TC.. 2151 series trigon inserts as specified by the manufacturer.

Always power down and lock out the lathe spindle before mounting or removing the toolholder from the tool post. Ensure the insert seating pocket and clamp screw are clean and free of chips before seating a new insert. Tighten the clamp screw to the torque value specified in the KENNAMETAL toolholder documentation — do not estimate clamp torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: STGCR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: TC.. 2151 trigon inserts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral, 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 0.38 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 0.62 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1224 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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1094421\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51748874584370,"sku":"1094421","price":131.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/903a432e3e26091d8d1bac07b5410720.jpg?v=1788899933","url":"https:\/\/voomisupply.com\/products\/kennametal-1094421-indexable-turning-toolholder-stgcr","provider":"Voomi Supply","version":"1.0","type":"link"}
