⚠️ Required: 0° Negative Relief Carbide Inserts (CN INSERT)
Per ISO 1832 nomenclature: the letter "N" in Position 4 of the tool holder code designates 0° negative relief — the strongest cutting edge geometry, used for heavy roughing and interrupted cuts. Per ISO 1832, the 2-letter prefix for the matching insert family is CN (NOT CC — that prefix means positive 7° relief inserts which will not seat correctly on this holder).
Compatible inserts (ISO 1832 "CN" negative family): CNMG / CNMM / CNGA / CNMX (C-shape, 0° negative, ISO 1832).
Why this matters: A negative-relief insert (e.g. CNMG) has its cutting edge set at 0° clearance, giving the strongest cutting edge for heavy roughing. A positive-relief insert (e.g. CCMT) has 7° clearance, giving a sharper but weaker edge — these are different insert families per ISO 1832. Pairing a negative-insert holder (CN INSERT = this catalog) with positive-relief inserts (CC family like CCMT) causes insert-pocket mismatch, chatter, premature wear, and insert breakage risk. Always verify Position 4 = "N" matches your insert series.
BEYOND-Original Tool Holders from Hangzhou, China
All 6 tool holders in this catalog are 100% genuine BEYOND — manufactured by BEYOND in Hangzhou, China. Each holder is CNC-machined from premium alloy steel (DIN 1.3343 / AISI M2 equivalent), heat-treated to HRC 60-62, and precision-ground for shank and pocket tolerances within ±0.01mm. Every tool holder follows the BEYOND 9-position code structure: a 5-letter prefix identifying fastening mode, insert shape, approach angle, relief angle, and hand direction, followed by a 4-digit shank spec identifying shank height, width, total length, and insert IC code.

Frequently Asked Questions
Are these genuine BEYOND original tool holders?
Yes — all 6 products in this catalog are 100% genuine BEYOND originals. Each holder is CNC-machined, heat-treated to HRC 60-62, and precision-ground at BEYOND's Hangzhou facility with full factory traceability. Every product is named according to the BEYOND official 9-position code structure documented in their catalog.
What does the BEYOND 9-position tool holder code mean?
Per the BEYOND catalog, the 9-position tool holder code identifies, in order: (1) Fastening mode — 7 types including S = central screw (most common), C = top clamp with pressure plate, D = dual clamping, M = strong multi-point clamping, P = pin/slot-lever clamp, A = back clamping, W = wedge clamping; (2) Insert shape (ISO 1832) — 7 shapes including C=80° rhombic, D=55° rhombic, R=round, S=square 90°, T=triangle 60°, V=35° rhombic, W=hexagon; (3) Approach angle — 22 letters covering 45° to 117.5° (A=90°, F/G=90°, J/U=93°, L=95°, H=107.5°, P=117.5°, etc.); (4) Relief angle — 6 angles (B=5°, C=7° standard, D=15°, E=20°, N=0°, P=11°); (5) Hand direction — L=left, R=right, N=no direction; (6) Shank height (mm); (7) Shank width (mm); (8) Shank total length code (K=125 mm standard, H=100 mm short, M=150 mm long, etc.); (9) Insert IC code (07=6.35 mm, 12=12.7 mm, 16=15.875 mm, etc.).
Are BEYOND tool holders compatible with other brands of carbide inserts?
Yes — BEYOND tool holders conform to ISO 1832 (insert shape) and ISO 5608 (insert pocket) standards, making them fully interchangeable with all major carbide insert brands including Sandvik, Kyocera, Mitsubishi, Sumitomo, Korloy, ZCC.CT, Walter, and Iscar. As long as the insert matches the holder's 9-position code (especially Position 2 = shape), it fits.
What shank sizes are available?
BEYOND tool holders are available in shank sizes from 1212H07 (12mm × 12mm short) through 3232P22 (32mm × 32mm extra long). Common sizes include 1212H07, 1212H11, 1616H07, 2020K16, 2525M11, 2525M16, and 3232P22. The format is AABB + length code + IC code, e.g. 2020K12 = 20×20 mm shank, 125 mm length, 12.7 mm insert IC.
What is the difference between R (right-hand) and L (left-hand) holders?
Right-hand (R) holders are the most common, used for standard lathe spindle rotations. Left-hand (L) holders are used on lathes with reverse spindle rotation or for special profiling applications. No-direction (N) holders can be used in both directions but with reduced rigidity.
How do BEYOND tool holders compare to Sandvik / Kyocera?
BEYOND tool holders match the ISO 1832/ISO 5608 dimensional specifications of leading global brands including Sandvik and Kyocera, at significantly lower price points. The premium alloy steel substrate (DIN 1.3343 equivalent) and HRC 60-62 heat treatment ensure equivalent rigidity and clamping force for production CNC turning environments.
What's the difference between S (screw) and M (multi-point) clamping?
Per BEYOND's catalog, the letter S at Position 1 designates a central screw clamp (the ISO standard screw-clamp, most common for general external turning) — the screw passes through the insert hole and threads into the holder pocket. The letter M at Position 1 designates a strong multi-point clamp (M-type) — multiple clamping points for the highest clamping force, ideal for heavy roughing and interrupted cuts.
