Key Features & Benefits
- ISO S20R-MWLNR08 designation — Standard pocket — takes any compliant WNMG080404 / WNMG080408 insert from Excision or other ISO suppliers.
- Internal turning ready — Designed to enter cast or pre-drilled bores for boring, finishing and shoulder turning operations.
- Solid steel body — One-piece bar resists deflection at the tip when set with the recommended overhang.
- Suitable for low-power lathes — Tip geometry and rake suit smaller workshop machines without stalling the cut.
- Australian supplier support — Backed by Excision Australia (Melbourne) — local stock with replacement parts available.
