BEYOND MDQNR / MDQNL External Turning Toolholders

The BEYOND MDQNR/L series is a high-performance external turning toolholder designed with M-type clamping (Clamp + Lock Pin), ensuring secure insert holding and excellent cutting stability. All models use DNMG inserts, where the last two digits of the toolholder code determine the insert size (e.g., 11 → DNMG11, 15 → DNMG15).

ISO Code Breakdown

• M – Clamping Method: Clamp + Lock Pin (M-type)
• D – Insert Shape: Diamond-shaped insert (D)
• Q – Cutting Edge Angle: 107.5°
• N – Insert Relief Angle: 0° relief
• R / L – Right-hand or Left-hand toolholder
• Four digits – Shank height × width (e.g., 2020 = 20×20 mm)
• Length Code – Overall toolholder length:
  • A = 32 mm
  • J = 110 mm
  • R = 200 mm
  • K = 125 mm
  • M = 150 mm
  • P = 170 mm
  • Q = 180 mm
• Last digits – Insert cutting edge length = DNMG insert size (11 / 15)

Insert Compatibility

All MDQNR/L models use the following insert format:
DNMG11 / DNMG15

Cutting Geometry

The 107.5° cutting edge angle provides excellent chip flow and is ideal for medium and finishing operations. The M-type clamping mechanism ensures stable insert holding during continuous or interrupted cutting.
