It features a 1 inch by 1 inch square shank with an overall length of 6 inches and a rake angle of -6 degrees. The toolholder uses a clamp-and-pin insert holding method and is compatible with CN..43.. style inserts, including the CNMG431-GN, with an inscribed circle of 0.5 inches. It is installed and serviced by machinists and CNC tooling technicians in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe 3606512 is suited for left-hand turning applications where the tool feeds from chuck toward tailstock or in specific facing and profiling operations requiring a left-hand cutting direction. The 5-degree lead angle and negative rake geometry support interrupted cuts and harder workpiece materials where edge strength is critical. This toolholder fits standard MCLN toolholder pockets and is a direct fit for setups requiring CN..43..-compatible insert geometry. It conforms to ISO 13399 tooling data standards, which simplifies integration into CAM and tool-management software.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand cutting direction with MCLN toolholder style for negative-rake turning\u003c\/li\u003e\n  \u003cli\u003eRake angle of -6 degrees for improved edge strength on demanding materials\u003c\/li\u003e\n  \u003cli\u003eClamp and pin insert holding method for secure insert retention under high cutting loads\u003c\/li\u003e\n  \u003cli\u003eCompatible with CN..43.. inserts including CNMG431-GN, inscribed circle 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e1 inch by 1 inch square shank, 6 inches overall length, 5-degree lead angle\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 tooling data standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eAccepts CN..43.. series inserts, including the CNMG431-GN.

Shut down spindle rotation and lock out the machine before changing toolholders or inserts. Ensure the shank pocket and clamping surfaces are clean and free of chips before seating the holder. Follow machine-tool manufacturer torque guidelines for toolholder clamping bolts — do not overtighten, as this can distort the shank or damage the insert seat.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MCLN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: -6 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.19 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: CN..43..
