$75.00
Item #624
The part number sequence SGUL-187-D8 (often cross-referenced with a master holder model like AGUOL-16) represents a vintage, highly rigid Carboloy Left-Hand Indexable Parting and Grooving Lathe Tool Holder designed for the GDN insert platform.Carboloy (a legacy brand historically tied to GE and later integrated into Seco Tools) engineered this setup specifically for heavy-duty, deep-reach cut-off operations on manual and CNC lathes.🛠️ Tool Specifications
- Brand: Carboloy (Seco)
- Holder Model: SGUL-187-D8
- Shank Size: 1\" Square Shank (1.00\" x 1.00\" standard cross-section for maximum rigidity).
- Hand / Orientation: Left Hand (L) — The \"L\" in SGUL dictates a left-hand orientation, meaning it is designed to cut toward the spindle or be mounted upside down in a rear tool post to drop chips downward.
- Insert Compatibility Width: 0.187\" (3/16 inch seat size).
- Insert Series: GDN series grooving/parting inserts.
📦 Applications & Insert ConfigurationThe inclusion of 3 new .187\" inserts makes this a complete, drop-in setup. The 0.187\" cut-off width provides a highly stable, heavy chip profile that resists tool deflection (walking) better than thinner 1/8\" (.125\") blades when cutting large-diameter solid bars. The GDN geometry utilizes an integrated top-clamp design or a pocket seat optimized to curl tough steel chips tightly so they don\'t pack tightly inside the deep slot.
