The toolholder features a square 3\/8 x 3\/8 inch shank and an overall length of 2.5 inches, making it well suited for compact turning operations where rigidity and insert stability are critical. Manufactured from steel with a neutral rake geometry at 0 degrees, it delivers consistent cutting geometry across a range of turning applications. Licensed machinists and CNC lathe operators typically specify this holder when running TC-style inserts on small- to medium-bore external turning setups.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is intended for use on CNC and manual lathes performing external turning operations. The STFC holder style is a standard configuration found in production turning, facing, and light profiling work. With a 1\/4-inch insert inscribed circle and a back-of-bar to cutting edge distance of 0.5 inches, this holder positions the insert precisely for consistent depth-of-cut control. It does not include coolant-through capability, so it is best suited for applications where external coolant delivery is sufficient. The screw-on series design allows for fast, repeatable insert indexing without the need for additional clamping hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSTFC toolholder style with right-hand cutting orientation\u003c\/li\u003e\n  \u003cli\u003eScrew clamping method for secure, repeatable insert seating\u003c\/li\u003e\n  \u003cli\u003eNeutral rake angle (0 degrees) compatible with a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e3\/8 x 3\/8 inch shank for use in standard square-shank tool blocks and turrets\u003c\/li\u003e\n  \u003cli\u003eOverall length of 2.5 inches with a head length of 0.62 inches\u003c\/li\u003e\n  \u003cli\u003eSteel construction — no coolant-through passage\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with TC-style triangular inserts with a 1\/4-inch inscribed circle (complete insert compatibility designation: TC.. 2151).

Ensure the lathe spindle is fully stopped and locked out before mounting or adjusting the toolholder in the turret or tool post. Torque the insert clamping screw to the insert manufacturer's specified value using the correct Torx or hex key — do not overtighten. Confirm tool centerline height relative to the spindle axis before taking the first cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: STFC\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\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\u003eShank Width\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 0.375 inches\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\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: TC.. 2151\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 0.151 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23153308\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: 1094409\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51749626380594,"sku":"1094409","price":129.81,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fb73c0cd04788922e6c3fab27cbf3332.jpg?v=1788908521","url":"https:\/\/voomisupply.com\/products\/kennametal-1094409-stfcr062-turning-toolholder-3-8-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
