Built from solid carbide, this right-hand cutting toolholder features a 1\/2 inch (12.70 mm) shank diameter and a minimum bore diameter of 0.5984 inches (15.20 mm). The bar measures 8 inches (203.20 mm) overall length and uses screw clamping to secure a single CCMT 21.51 insert. Coolant-through capability supports chip evacuation and tool life in demanding cuts. It carries a neutral rake angle and a 0-degree lead angle, making it suitable for general-purpose internal stock removal.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is used in precision turning applications where tight bore tolerances are required. The E-SCLC toolholder style accommodates CCMT 21.51 inserts with a 1\/4 inch inscribed circle, allowing machinists to select insert grades matched to the workpiece material. The multi-use designation means the same bar supports both boring and internal turning in a single setup, reducing tool changes. Typical installations are performed by CNC machinists and toolroom professionals working on lathes and live-tool turning centers in job shop, production, and maintenance machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and vibration resistance in small-bore applications\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 0.5984 inches (15.20 mm) suits tight-clearance internal work\u003c\/li\u003e\n  \u003cli\u003eScrew clamping holds CCMT 21.51 inserts securely under interrupted and continuous cuts\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design directs fluid to the cutting zone for improved chip control and insert life\u003c\/li\u003e\n  \u003cli\u003eNeutral rake with 0-degree lead angle provides predictable cutting forces on a wide range of materials\u003c\/li\u003e\n  \u003cli\u003eMulti-use capability supports both boring and internal turning without a toolholder change\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CCMT 21.51 inserts (1\/4 inch inscribed circle).

Power down and lock out the machine spindle before inserting or changing the boring bar or insert. Ensure the shank is fully seated and clamped to the specified tool block or turret pocket before resuming operation.
