Iscar 26mm Parting Blade Block SGTBN 19-5

Description Product Overview The Iscar SGTBN 19-5 is a heavy-duty, solid-construction Parting Blade Tool Block, designed to rigidly clamp indexable cutoff and grooving blades for CNC turning centers and manual lathes. One-Piece Rigidity: Unlike adjustable or multi-piece holders that can introduce flex, this block features a solid, one-piece body design. This maximizes vibration dampening and rigidity, which is absolutely critical for achieving clean finishes and preventing chatter during deep parting operations. Secure 3-Bolt Clamping: The blade is locked into place using a robust 3-bolt clamping mechanism. This ensures even pressure across the blade shank, preventing it from slipping or pivoting under heavy cutting loads. Custom 26mm Adaptation: The block’s native shank size is 19mm. However, this specific unit features a custom-fitted, screw-on extension plate that perfectly builds the shank out to fit securely into a 26mm toolpost. This gives you the versatility of a larger mount without sacrificing the block’s inherent strength. Condition Used (Patina / No Major Damage). This tool holder is in well-used condition and wears the visual patina of a veteran shop-floor tool. Structural Integrity: Despite the cosmetic aging and surface wear, there is no major damage. The blade pocket is clean, the clamping threads are intact, and it has not suffered any catastrophic crashes that would compromise its rigidity or holding power. Brand Information Iscar (Israel) is a global leader in metal removal technology and the undisputed pioneer of modern parting and grooving systems. Their SGTBN series tool blocks are legendary in the machining industry for their robust steel construction and ability to handle high-feed production environments day in and day out.
