BEYOND SCBCR/L External Turning Toolholders | Screw Clamp Type CNC Lathe Toolholder for C-Shape Inserts

BEYOND SCBCR/L External Turning Toolholder – Screw Clamp Type

The BEYOND SCBCR/L series is a high-precision external turning toolholder using a screw-clamp system. All models follow ISO coding: the model name encodes clamping, insert family, holder style, clearance angle, hand, shank dimensions and insert edge length. These holders are optimized for CNC lathes machining steel, stainless steel and cast iron.

ISO Code Interpretation (Corrected)

• 1st Letter – S = Screw clamp clamping method
• 2nd Letter – Insert Shape (e.g. C = 80° rhombic / diamond)
• 3rd Letter – Holder Style (e.g. B = specific external holder style)
• 4th Letter – Clearance Angle (e.g. C = 7° positive)
• Important: Insert family / model code is formed by combining the 2nd and 4th letters. For example 2nd = C and 4th = C → insert family = CC.. (compatible with CCMT / CCGT series).
• 5th Letter – Hand: R = Right, L = Left
• Next digits – Shank height × width in mm (e.g. 2020 = 20×20)
• Following letter – Holder length type (H / K / M etc.)
• Last digits – Insert cutting edge length code (09 / 12 etc.)

Product Features

• Rigid screw-clamp insert locking for higher stability
• Insert family derived from ISO code (2nd + 4th letters)
• 7° positive clearance angle for smooth cutting
• Precision ground shank for accurate machine fit
• Ideal for finish and semi-finish turning of steel, stainless steel and cast iron

Available Models & Technical Specifications (Corrected Insert Codes)

Recommended Applications

• External turning and profiling
• Medium-to-finish passes on steel and stainless steel
• Applications requiring precise insert positioning and chip control

Note: Insert family code shown above (e.g. CC..09T3.. / CC..1204..) is derived from the combination of the 2nd and 4th ISO letters (Insert Shape + Clearance Angle). Use corresponding CC-series inserts (CCMT / CCGT) matching the cutting-edge length and chipbreaker type for best results.
