BEYOND MTBNR/L CNC Turning Toolholder for TNMG1604 Inserts
The BEYOND MTBNR/MTBNL toolholder series is designed for high-strength CNC external turning using TNMG1604 carbide inserts. Featuring a reliable M-type clamp with lock pin and a precise 75° approach angle (ISO code letter “B”), this toolholder ensures rigid clamping, excellent chip control, and stable performance in heavy-duty and continuous machining.
✔ ISO Code Interpretation (MTBNR / MTBNL)
- M – M-type clamp + Lock Pin system
- T – Insert Shape: Triangular (TNMG)
- B – Cutting Edge Angle = 75°
- N – 0° Insert Relief Angle
- R / L – Right-hand / Left-hand toolholder
- 4-digit number – Shank Height × Width (mm)
- Length Code Letter – Determines total toolholder length
- Final “16” – Insert cutting edge length
✔ Features
- Strong M-type wedge clamp with additional lock pin
- Optimized for 75° approach angle roughing and semi-finishing
- Stable insert positioning for high-feed machining
- Compatible with all TNMG1604 carbide inserts
- Heat-treated steel shank for maximum rigidity
- Suited for steel, stainless steel, alloy steel, and cast iron
✔ Compatible Inserts
TNMG1604 (all grades and chipbreaker designs)
✔ Applications
