Cutting tool guides

Short, practical notes on choosing saw blades and tooling — written for buyers who compare specifications rather than slogans.

• TCT vs PCD saw blades: which one for your material? — When tungsten carbide (TCT) pays off, when diamond (PCD) is the only option, and how to compare them on cost per cut instead of unit price.
• Saw blade tooth geometry: what the letters actually mean — A plain-language key to the tooth codes printed in a catalogue — WT, AT, TT, SBL, SBR, CB, WWT and the rest — and which material each one suits.
• Choosing a saw blade manufacturer in China: a buyer's checklist — Nine checks that separate an OEM-grade cutting tool factory from a trading company, and the documents to ask for before the first order.
