How to Choose the Right BEYOND Tool Holder (9-Position Code Decision Tree)
Selecting the correct BEYOND tool holder follows the 9-position code in sequence per the official catalog:
- Position 1 — Fastening mode: S = central screw (ISO standard, most common for screw-clamp holders); C = top clamp with pressure plate (economical); D = dual clamping (top + side); M = strong multi-point clamping (heavy roughing); P = pin / slot-lever clamp (no insert hole); A = back clamping; W = wedge clamping.
- Position 2 — Insert shape (ISO 1832): Match your insert series — C 80° rhombic (CCMT/CCGT family), D 55° rhombic (DCMT/DCGT), R round (RCMT for 70° countersink or RPMT for 90° countersink), S square (SCMT/SCGT), T triangle (TCMT/TCGT), V 35° rhombic (VCMT/VCGT + VBMT/VBGT), W hexagon (WNMG/WCMX).
- Position 3 — Approach angle: F 90°; G 45°; J 93°; L 95°; H 107.5°; P 117.5°; A 90°; B/K/R 75°; D/S/T/Q 45°; E 60°; N 63°; V 72.5°; U 93°; W 50°; Y 85°. Choose by shoulder clearance / profiling depth.
- Position 4 — Relief angle: C 7° (standard, most common); B 5°; D 15°; E 20°; N 0° (negative, heavy roughing); P 11° (positive, finishing).
- Position 5 — Hand: R Right-hand (most common); L Left-hand; N No direction (universal, both hands).
- Positions 6-7 — Shank height × width (mm): 1212 / 1616 / 2020 / 2525 / 3232 etc. For 12-station CNC lathes use 1212 or 1616; for heavy-duty lathes use 2525 or 3232.
- Position 8 — Shank total length code: K 125 mm (standard, most common); H 100 mm (short); M 150 mm (long); P 170 mm (extra long); full range 32-500 mm.
- Position 9 — Insert IC code: 07 = 6.35 mm, 09 = 9.525 mm, 12 = 12.7 mm, 16 = 15.875 mm, 19 = 19.05 mm, 25 = 25.4 mm.
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.
Frequently Asked Questions
Are these genuine BEYOND original tool holders?
Yes — all 57 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.
