BEYOND MSRNR / MSRNL External Turning Toolholders

The BEYOND MSRNR/L toolholder series is designed for external turning applications using M-type clamping with clamp + lock pin, providing stable insert seating and excellent performance in medium and heavy machining. All holders use SNMG inserts, with the insert size determined by the last two digits of the model (12 / 15 / 19).

ISO Code Breakdown

• M – Clamping Method: Clamp + Lock Pin (M-type)
• S – Insert Shape: Square (S)
• R – Cutting Edge Angle: 75° approach angle
• N – Insert Relief Angle: 0° relief (N type)
• R / L – Hand of Toolholder: Right-hand (R) or Left-hand (L)
• Four Digits – Shank Height & Width (e.g., 2020 = 20×20 mm)
• Length Code – Toolholder length:
  • K = 125 mm
  • M = 150 mm
  • P = 170 mm
• Last Digits – Insert cutting edge length (12 / 15 / 19 → SNMG12 / SNMG15 / SNMG19)

Insert Compatibility

All MSRNR/L models use the following insert format:
SNMG + (12 / 15 / 19)

Cutting Geometry

Main Approach Angle (75°): Ideal for semi-finishing and heavy roughing on steels, stainless steels, alloy steels, and cast irons. The M-type clamp system ensures secure holding under high cutting loads, extending insert life.

Features

• High rigidity shank design
• Suitable for SNMG double-sided negative inserts
• 75° approach angle optimized for heavy cutting
• Precision ground pocket for better insert stability
• Available in multiple shank sizes
