Built from steel with a 3\/4 inch by 3\/4 inch square shank and an overall length of 4.5 inches, it accepts TN..33. series triangular inserts secured by a clamp and screw holding method. The negative rake angle of -5 degrees promotes edge strength and is well suited for interrupted cuts and harder workpiece materials. Installation and indexing are straightforward, making this a reliable choice for production turning environments. Machinists and CNC lathe operators working in job shops or manufacturing facilities are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis toolholder fits standard MTFN left-hand turning applications where the tool approaches the workpiece from the right side of the turret. The 3\/8 inch insert inscribed circle and the back-of-bar to cutting edge distance of 1 inch provide predictable tool offset geometry for programming. It is suited for both roughing and finishing passes depending on insert grade and geometry selection. No coolant-through capability is present, so external flood or mist coolant delivery should be planned at the machine level.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand MTFN holder style for right-to-left cutting direction on the lathe\u003c\/li\u003e\n  \u003cli\u003eNegative rake angle of -5 degrees for improved insert edge strength on demanding cuts\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch by 3\/4 inch steel shank fits standard lathe tool blocks and turret pockets\u003c\/li\u003e\n  \u003cli\u003eClamp and screw insert holding method provides secure, repeatable insert seating\u003c\/li\u003e\n  \u003cli\u003eAccepts TN..33. triangular inserts with a 3\/8 inch inscribed circle\u003c\/li\u003e\n  \u003cli\u003ePart of the Multi-Option series for broad insert grade and geometry availability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with TN..33. series triangular indexable inserts, specifically TN.. 322 geometry.

Always power down and lock out the machine before mounting or changing toolholders in the turret. Torque the insert clamp screw to the insert manufacturer's specification using the appropriate torx or hex key. Verify tool offset and edge height to centerline before resuming cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MTFN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\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: -5 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 0.94 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: TN..33.
