The SNGR inner groove hole indexable lathe turning tool holder is designed to securely mount indexable turning tools with inner groove holes in a lathe. It is offered in model variants 08J07, 10K08, 12M08, 16Q09, 20R09 and is suitable for turning tools in the 6GR, 7GR, 8GR, and 9GR families, including 8GR and SNGR14M08, with a width of 100. Key benefits Precise alignment and reduced tool runout through inner groove hole clamping for stable cutting and consistent inserts seating. Quick tool changes enabled by the indexable design, reducing machine downtime and increasing productivity. Broad compatibility with multiple GR sizes (6GR, 7GR, 8GR, 9GR) and special mentions of 8GR and SNGR14M08, allowing mixedtool setups on a single holder. Reliable performance for routine turning tasks in a environment, backed by the SNGR design lineage. Key attributes Brand and type: SNGR inner groove hole indexable lathe turning tool holder Model variants: 08J07, 10K08, 12M08, 16Q09, 20R09 Width: 100 Compatible turning tool sizes: 6GR, 7GR, 8GR, 9GR; includes 8GR and SNGR14M08 Application scope: core lathe turning and related operations that use inner groove hole indexable tools Use cases Case 1: External turning on a CNC lathe using 8GR inserts mounted in the holder for consistent tool engagement and repeatable dimensions. Case 2: Grooving operations that rely on inner groove hole inserts, enabling secure seating and easy indexable changes. Case 3: Mixedtool setups in production where tools of sizes 6GR–9GR (notably 8GR and SNGR14M08) need to be swapped quickly without changing the holder, improving workflow efficiency.
