What is the Sy Tools 8-family?

Eight electroplated-diamond lines from the brand: D, KD, LVD, RO, SU, TTD, WWD and FW. All use electroplated diamond, dry-use, anodized aluminium/ABS base, and fit Ruixin/Tsprof/KME guides.

How is WWD different from D, KD and LVD?

Same family. D is the 160×22×8 mm universal; LVD is 158×20×5 mm with a double 45° bevel for guided systems; KD is the balanced pick; WWD is another member of the family — exact grit numbers and size to be confirmed against the Ozon SKU.

No. Sy Tools WWD is dry-use; a light spritz only rinses metal swarf.

Will it fit my guide?

The standard-width base fits Ruixin/Tsprof/KME and clones; check the slot geometry of your carriage.

Sy Tools WWD Series Diamond Stone Review: Where It Sits in the 8-Family (vs D/KD/LVD/RO/SU/TTD/FW)

Sy Tools groups its diamond stones into an "eight-family": D / KD / LVD / RO / SU / TTD / WWD / FW. Today in the Ruimo Tech lab, I'm Engineer Yanchi Li, and I'm putting Sy Tools WWD under the light — where it sits and why it earns a place.

Sy Tools WWD diamond stone — Fig. 1: Sy Tools WWD, electroplated diamond on a rigid base.

1. What's inside Sy Tools WWD

Sy Tools WWD is an electroplated (galvanic) diamond stone. Diamond grit is held in a nickel bond on a rigid anodized-aluminium/ABS base. The bond doesn't creep under heat — that's why, in 2026, most brands (including Sy Tools) moved from plastic to metal, so the angle repeats pass to pass.

2. WWD against the rest of the eight-family

Spec	Sy Tools WWD	Sy Tools D	Sy Tools LVD	Sy Tools KD
Family	one electroplated 8-family (D/KD/LVD/RO/SU/TTD/WWD/FW)
Size (D)	per Ozon SKU (to-verify)	160×22×8 mm	158×20×5 mm	balanced
Base	anod. Al/ABS	ABS/Al	anod. Al	anod. Al/ABS
Ends	standard	flat	double 45°	standard
Position	family member	hand+guide	guided-only	balanced

All four are electroplated diamond, dry-use, and fit Ruixin/Tsprof/KME. WWD is a full member of the family; exact WWD grit numbers are marked "to-verify" — check the Ozon SKU.

3. Picking a WWD grit

The grit logic across Sy Tools WWD mirrors the whole eight-family: dull → coarse start, daily → mid, finish → fine. For max cross-brand fit, D (22 mm universal width) wins; for zero-play in guides, LVD; for a balanced workhorse, KD or RO; WWD is another solid pick for your sequence (exact numbers per Ozon SKU).

4. Pros & cons (honest)

✅ Pros

Electroplated diamond — fast, predictable cutting.
Rigid base doesn't creep with heat; repeatable angle.
Dry-use; fits Ruixin/Tsprof/KME.

⚠️ Cons

Exact WWD grits/size to be confirmed against Ozon SKU.
Electroplated layer can't be repaired if chipped.
Mirror finish still needs a strop (Sy Tools wood-strops/KD-A11).

5. Verdict

Choose Sy Tools WWD when you want another reliable diamond stone from the Sy Tools family for your sequence. Pair with Sy Tools T05-AMZ for angle and Sy Tools wood-strops or KD-A11 for the finish. Price on Ozon (family ~$12.99).

Ruimo Tech lab notes. Specs (electroplated diamond, dry-use, Ruixin/Tsprof/KME fit, eight-series D/KD/LVD/RO/SU/TTD/WWD/FW) verified against the Sy Tools listing; exact WWD grit numbers marked to-verify per Ozon SKU. No fabricated ratings.
