How to Choose the Right BEYOND Tool Holder (5-Letter Code Decision Tree)
Selecting the correct BEYOND tool holder follows the 5-letter code in sequence per the official catalog:
- Position 1 — Fastening mode (夹紧方式): S = single central screw (ISO standard, most common for screw-clamp holders); C = single top screw (economical); A = top-clamp with bridge; M = multi-lock (pin + wedge, highest rigidity); D = double clamp; E = side lever; JS = J-style side screw; P/Q = pin clamp.
- Position 2 — Insert shape (刀片形状, ISO 1832): Match your insert series — C 80° rhombic (CN/DN), D 55° rhombic, K 55° parallelogram (heavy), R round, S square (SN/SC), T triangle (TN/TC), V 35° rhombic (VB/VC), W trigon (WN).
- Position 3 — Cut-in angle (切入角): F/G 91°; J/J2 93°; L/L2 95°; A 90°; B/K 75°; D 60°; N/N3 63°; P 62.5°; S 72.5°; X 100°; Y 80°. Choose by shoulder clearance / profiling depth.
- Position 4 — Relief angle (刀片后角): C 7° (standard, most common); B 5° (medium); N 0° (negative, heavy roughing); P 11° (positive, finishing).
- Position 5 — Hand (方向): R Right-hand (most common); L Left-hand (for reverse spindles or special profiling); N Neutral (universal, both directions).
Shank size (after the 5-letter code) follows AABBCTNN format — AA = shank height (mm), BB = shank width (mm), C = length code (H=short, K=standard, M=long, P=extra long), NN = insert IC code (07=6.35mm, 09=9.525mm, 12=12.7mm, 16=15.875mm). For CNC lathes with 12-station turrets, choose compact 1212H07 or 1616H07 shanks. For heavy-duty lathes, use 2525M16 or 3232P22 for rigidity.
Tip: All BEYOND tool holders are interchangeable with leading carbide insert brands per ISO 1832 (insert shape) and ISO 5608 (insert pocket). Inserts from Sandvik, Kyocera, Mitsubishi, Sumitomo, Korloy, ZCC.CT, Walter and Iscar all fit matching BEYOND holders.

Every product is named according to the BEYOND official 5-letter code structure documented in their catalog (page 20).
What does the BEYOND 5-letter tool holder code mean?
Per the BEYOND catalog page 20, the 5-letter tool holder code identifies, in order: (1) Fastening mode (夹紧方式) — 9 types including S = single central screw (most common), C = single top screw, A = top-clamp bridge, M = multi-lock, P/Q = pin clamp, D = double clamp, E = side lever, JS = J-style side screw; (2) Insert shape (刀片形状, ISO 1832) — 8 shapes including C=80° rhombic, D=55° rhombic, K=55° parallelogram, R=round, S=square 90°, T=triangle 60°, V=35° rhombic, W=trigon; (3) Cut-in angle (切入角) — 22 letters covering 45° to 100° (A=90°, F/G=91°, J=93°, L=95°, etc.); (4) Relief angle (刀片后角) — B=5°, C=7° (standard), N=0°, P=11°; (5) Hand direction (方向) — L=left, R=right, N=neutral.
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 5-letter 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 four-digit shank code uses AABB (height+width in mm) + length letter (H=short, K=standard, M=long, P=extra long) + IC code (07=6.35mm, 09=9.525mm, 12=12.7mm, 16=15.875mm).
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. Neutral (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-lock) clamping?
Per BEYOND's catalog, the letter S at Position 1 designates a single central screw (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 multi-lock clamp (M-type) — the insert is held by a combination of pin (through insert hole) plus a top clamp wedge, providing the highest rigidity for heavy roughing and interrupted cuts.
