Built from steel, it accepts A-STFP style inserts secured by a screw-clamp holding method and features a through-coolant channel to direct fluid directly to the cutting zone. The 3\/8-inch shank diameter and 6-inch overall length make it well suited for reaching into confined bore geometries. A neutral rake angle of 0 degrees provides a stable cutting geometry across a range of workpiece materials. This toolholder is selected and installed by machinists and tool-room technicians in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThe 7000083 is intended for boring operations requiring a minimum bore diameter of 0.48 inches. The through-coolant capability makes it practical for deep-bore applications where chip evacuation and heat control are critical. The left-hand orientation suits specific spindle rotation or part-geometry requirements where a right-hand bar is not appropriate. The back-of-bar to cutting edge and center-to-cutting-edge dimensions are both 0.25 inches, supporting accurate tool offset setup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMinimum bore diameter of 0.48 inches for small-bore internal turning\u003c\/li\u003e\n\u003cli\u003eLeft-hand holder orientation for reverse-rotation or specific geometry applications\u003c\/li\u003e\n\u003cli\u003eThrough-coolant channel with a 0.125-inch coolant hole diameter for direct cutting-zone cooling\u003c\/li\u003e\n\u003cli\u003eScrew-clamp insert holding method for secure, repeatable insert seating\u003c\/li\u003e\n\u003cli\u003eAccepts 1\/4-inch inscribed circle, 3\/32-inch thick A-STFP TP.. series inserts\u003c\/li\u003e\n\u003cli\u003eNeutral 0-degree rake angle for broad material compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with A-STFP style TP.. series indexable inserts with a 1\/4-inch inscribed circle and 3\/32-inch insert thickness.

Secure the 3\/8-inch shank firmly in the toolholder or turret and verify tool offset values match the 0.25-inch center-to-cutting-edge dimension before cutting. Connect the through-coolant supply line before running the spindle and confirm coolant flow is unobstructed. Always index or replace the insert with the machine stopped and power isolated from the spindle drive.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.48 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: A-STFP\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 Compatibility\u003c\/strong\u003e: TP..
