✔️ Insert size 3.1mm width, 11.3mm length, 0.2mm radius, 0° lead
These GTN-3 SP300 grooving carbide inserts are precision tools for CNC lathes, designed for cut-off and grooving operations. With a CVD yellow coating, they deliver smooth finishes, reduced cutting forces, and longer tool life. This 10-piece pack fits SPB326 and SPB332 holders for reliable, consistent machining in metalworking projects.
✅ 3.1mm (0.122") width, 11.3mm (0.445") length, 0.2mm (0.008") radius, 0° lead angle✅ CVD yellow coating for wear resistance and heat resistance; smooth finish
✅ Solid carbide body for toughness and long tool life
✅ Fits SPB326/332 and SPH grooving and cut-off holders for CNC lathe setups
💡 What is a grooving carbide insert and why should I choose it for CNC turning?
These inserts provide precise cut-off and groove work with a coated surface that resists heat and wear.
- Handy for clean, accurate grooves on rotating parts - 0° lead angle helps reduce cutting forces and heat buildup - CVD yellow coating improves finish and tool life - Fits common holders like SPB326/332 for easy interchange
