SNGR Inner Groove / Hole Indexable Lathe Turning Tool Holder Models: SNGR 08J07, 10K08, 12M08, 16Q09, 20R09 Compatible with: 6GR, 7GR, 8GR, 9GR turning tool systems Note: for 8GR option, NO cutter bar and NO insert are included Why you need this tool holder Designed specifically for internal grooving and hole turning operations on lathes, this SNGR indexable tool holder lets you perform precise, repeatable cuts with minimal setup time. Indexable design reduces downtime: change or rotate inserts quickly without regrinding, improving productivity and tool life management. Compatibility with GRseries turning tools makes it easy to integrate into existing tooling setups (6GR/7GR/8GR/9GR), so you can expand capabilities without replacing your toolpost or holders. Key features and benefits Purposebuilt for inner groove and hole turning: supports internal cutting operations where access and stability are critical. Indexable functionality: accepts indexable inserts for fast replacement and consistent cutting geometry. Multiple model options: SNGR 08J07, 10K08, 12M08, 16Q09, 20R09 give you choice for varying task sizes and toolpost configurations. GRseries compatibility: fits 6GR, 7GR, 8GR, and 9GR turning tools, simplifying selection and interchangeability. Clear supply note: 8GR option is sold without cutter bar and without insert (NO cutter bar, NO insert) — confirm included items when ordering. Applications and use cases Internal grooving in parts such as bearing races, piston cups, or sealing grooves where precision and surface finish matter. Hole turning and light internal profiling inside cylindrical workpieces for prototype, , or production operations on manual or CNC lathes. Retrofit or expand an existing GRseries tooling setup to add internal grooving capability without replacing the entire tool system. What to consider before ordering Select the correct SNGR model (08J07, 10K08, 12M08, 16Q09, 20R09) based on the required reach and clearance for your specific internal operation. Verify GR compatibility with your existing turning tools (6GR, 7GR, 8GR, 9GR). Be aware that the 8GR option is explicitly listed with NO cutter bar and NO insert; confirm whether inserts and cutter bars are required and them separately if needed. Practical advantages Faster insert changes and consistent indexable geometry reduce setup time and scrap. Standardized compatibility with GRseries holders simplifies inventory and tooling logistics. Multiple model options provide flexibility to match part dimensions and machining access. Use this SNGR inner groove/hole indexable lathe turning tool holder to add reliable, indexable internal grooving capability to GRseries turning setups. Verify model selection and included components (particularly for 8GR) before finalizing your .
