Built to the A4SM toolholder style, it accepts A4..03.. series inserts secured by a clamp-style insert holding method for reliable, repeatable positioning. The toolholder is configured for left-hand orientation and delivers a minimum groove width of 3 mm (0.118 inches) with a maximum depth of cut of 14 mm (0.55 inches). The square shank measures 5\/8 x 5\/8 inches (15.88 x 15.88 mm) with an overall length of 127 mm (5 inches). Machinists and tooling technicians working in production turning environments use this holder for precise groove profiling and parting operations.\u003c\/p\u003e\n\u003cp\u003eThe 1953178 is suited for external grooving and cutoff applications in production and job-shop turning environments. Its left-hand configuration makes it appropriate for specific turret positions and machine setups where right-hand holders are not compatible. The A4 series design is commonly applied in applications requiring consistent groove geometry and controlled depth of cut on bar stock, tubing, and turned components across a range of materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand external grooving and cutoff configuration for turret flexibility\u003c\/li\u003e\n  \u003cli\u003eMinimum groove width of 3 mm (0.118 inches) for tight-tolerance groove profiles\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 14 mm (0.55 inches) for deeper grooving and parting operations\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert retention for secure indexable insert positioning\u003c\/li\u003e\n  \u003cli\u003eCompatible with A4..03.. series inserts for a range of groove widths and geometries\u003c\/li\u003e\n  \u003cli\u003e5\/8 x 5\/8 inch square shank for standard toolpost and turret mounting\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design; suitable for external flood coolant application\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with A4..03.. series indexable inserts.

Confirm the shank is fully seated and clamped to the specified tool block torque requirements per the machine tool manufacturer guidelines. Inspect insert seating and clamp condition before returning the machine to operation. Do not exceed the rated depth of cut for the insert and holder combination in use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: A4SM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal or External\u003c\/strong\u003e: External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: A4..03..\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Groove Width\u003c\/strong\u003e: 3 mm (0.118 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 14 mm (0.55 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 5\/8 inch (15.88 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 5\/8 inch (15.88 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 3.622 inches (92 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 1.03 inches (26.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.38 inches (35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches (127 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius Insert\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.56 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: 1953178\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743479922994,"sku":"1953178","price":265.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3deb79aa976575f240efc95372f54050.jpg?v=1788847497","url":"https:\/\/voomisupply.com\/products\/kennametal-1953178-grooving-cutoff-toolholder-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
