BEYOND MSSNR / MSSNL External Turning Toolholders

The BEYOND MSSNR/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 SNMG inserts, where the last two digits of the toolholder code determine the insert size (e.g., 12 → SNMG12, 19 → SNMG19).

ISO Code Breakdown

• M – Clamping Method: Clamp + Lock Pin (M-type)
• S – Insert Shape: Square insert (S)
• S – Cutting Edge Angle: 45° approach angle
• 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:
  • H = 100 mm
  • K = 125 mm
  • M = 150 mm
  • P = 170 mm
  • R = 200 mm
• Last digits – Insert cutting edge length = SNMG insert size (12 / 19)

Insert Compatibility

All MSSNR/L models use the following insert format:
SNMG12 / SNMG19

Cutting Geometry

The 45° approach angle provides excellent chip control and is ideal for medium machining, semi-finishing, and profiling. The M-type clamping mechanism offers improved insert rigidity during continuous or interrupted cutting.

Key Features

• Strong M-type clamping with clamp + lock pin
• Compatible with SNMG double-sided inserts
• 45° approach angle for versatile turning operations
• Stable for medium to heavy cutting applications
• Available in multiple shank sizes and lengths
