It uses a screw-clamp insert holding method with a neutral rake angle of 0 degrees, providing stable, repeatable cutting performance. The shank measures 0.625 inches wide by 0.630 inches high with an overall length of 4 inches. This toolholder is built from steel and accepts TC-style trigon inserts with a 3\/8-inch inscribed circle. It is installed by machinists and toolroom technicians in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis toolholder is suited for left-hand turning applications where tool approach direction requires a left-hand orientation. It is commonly mounted on turret-style lathes and CNC turning centers in both production and job-shop settings. The screw-on series design ensures secure insert seating during interrupted and continuous cuts. Compatible insert geometry is the TC.. 3252 family, which covers standard trigon insert configurations appropriate for a range of ferrous and non-ferrous workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSTGC-style toolholder with left-hand orientation for specific approach and clearance requirements\u003c\/li\u003e\n\u003cli\u003eScrew-clamp insert holding method for positive, repeatable insert indexing\u003c\/li\u003e\n\u003cli\u003eNeutral rake angle (0 degrees) for broad material compatibility\u003c\/li\u003e\n\u003cli\u003eSteel construction for rigidity and durability under cutting loads\u003c\/li\u003e\n\u003cli\u003e4-inch overall length with 3\/4-inch back-of-bar to cutting edge distance\u003c\/li\u003e\n\u003cli\u003eNo coolant-through configuration  -  external coolant application applies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eAccepts TC.. 3252 series trigon inserts with a 3\/8-inch (0.375-inch) inscribed circle.

Ensure the lathe or turning center is fully powered down and the spindle is locked before mounting or removing the toolholder from the turret. Use the appropriate torque wrench and insert screw driver for the clamping screw to avoid stripping the screw seat. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when setting tool offsets after installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: STGC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left 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.. 3252\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 0.630 inches (15.88 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\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\u003eWeight\u003c\/strong\u003e: 0.54 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1094428\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51782782189874,"sku":"1094428","price":156.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fa173825b93e78c07d382cc54cee283a.jpg?v=1789181703","url":"https:\/\/voomisupply.com\/products\/kennametal-1094428-indexable-turning-toolholder-stgcl103","provider":"Voomi Supply","version":"1.0","type":"link"}
