BEYOND SDACR/L External Turning Toolholders – Screw Clamp Type (Corrected)

The BEYOND SDACR and SDACL series are high-precision CNC external turning toolholders designed for diamond-style carbide inserts (example insert code: DCMT). With a secure screw-clamp mechanism (S-type), these holders deliver excellent rigidity, stable insert seating, and reduced vibration for finishing and semi-finishing operations.

Corrected ISO Code Structure – SDACR / SDACL

Note: After the initial clamping-letter, the following letters (positions 2–5) represent the insert designation (for example DCMT), not separate unrelated fields.

• 1st letter – Clamping Method of Insert: S = Screw clamp
• 2nd–5th letters – Insert Model / Code: e.g. DCMT
  • D – Insert geometry (55° diamond)
  • C – Relief / nose designation (common in DCMT naming)
  • M – Size/series indicator in the insert code
  • T – Thickness / tolerance / chipbreaker family indicator
• 6th position (next char) – Holder Hand: R / L / N (Right / Left / Neutral)
• Next 4 digits – Shank Height × Width (e.g., 1212 = 12 × 12 mm)
• Length letter – Holder length code (H / F / K / M / etc.)
• Final number – Insert cutting-edge length / insert series (e.g., 07 / 11)

Key Features (unchanged)

• Screw-clamp design for secure insert locking and high rigidity
• Optimized for DCMT (55° diamond) series inserts — also compatible with DCGX / DCMX families
• High-strength alloy tool steel for durability and vibration resistance
