Metal Circular Saw Blades: How to Spec TCT

Practical guide about TCT circular saw blade metal cutting for metal cutting buyers, distributors, and OEM customers.

Updated: October 19, 2026 · LIZEN Sawing Knowledge

Short answer: To quote a metal circular / TCT cold saw blade for the metal industry, send diameter × bore × kerf (and plate/body thickness if known) × tooth count, plus material (steel / stainless / aluminum), solid vs tube / profile with wall thickness, and machine model. Match blade type to the material (steel-focused TCT cold saw vs aluminum blade), confirm bore and pin-hole fit, then check coolant, clamping and feed on the machine. Confirm with machine model, application data, and a controlled sample test.

What LIZEN supplies

LIZEN supplies TCT cold saw blades, aluminum saw blades, and HSS circular saw blades. Quotations use diameter, bore, kerf, tooth count, material, and machine model — the same field set as the category page. Confirm availability per order and specification.

Diameter, bore, kerf, plate — what each means

Diameter — must fit machine max and cutting capacity

Diameter (OD) must sit within the machine’s maximum blade size and still leave capacity for the section you cut. Read it from the nameplate, model sheet, or the blade you run today. Do not step up diameter without checking guards, flanges and motor capacity.

Bore and pin-hole / drive-pin pattern — exact match

Bore must match the arbor exactly. Many machines also use pin holes or drive pins on a fixed pitch-circle diameter (PCD). Send the pattern, or a clear photo of the blade flange side and the machine flange. Improvised adapters and drilled-out bores cause vibration and tip damage — do not improvise.

Kerf vs plate thickness — cutting width vs body

Kerf is the cutting width (material removed). Plate is the body thickness behind the tips. Specs are often written as kerf/plate. Send both if listed. LIZEN does not publish a preferred kerf chart here; confirm available combinations with LIZEN for your machine.

Tooth count and geometry (logic only)

Tooth count (Z) and geometry depend on diameter, material, solid vs tube/thin-wall, and wall thickness.

Solid vs tube / thin-wall

Starting logic (confirm with LIZEN):

Thin-wall tube and light profiles often need more teeth to reduce tooth shock and burr risk.
Solid bar and heavy sections often need fewer teeth and more gullet so chips clear.

These are heuristics, not LIZEN tooth charts. Send section size and wall with the RFQ. Do not treat competitor HSS RPM or tooth tables as LIZEN TCT specs. Confirm with machine model, application data, and a controlled sample test.

Steel / stainless TCT cold saw vs aluminum circular blades

LIZEN’s public split is TCT cold saw blades (steel / stainless) and aluminum saw blades (profiles and extrusions). Do not assume a steel blade is correct for aluminum, or the reverse.

Feature	Steel / TCT cold-saw focus	Aluminum blade focus	Status
Typical applications	Carbon / alloy / stainless bar, tube, structural sections on cold-saw style machines	Aluminum profiles, extrusions, light alloys where surface and chip control matter	Site category split; confirm per order
Tooth / geometry note	Geometry chosen for ferrous cutting and chip load on the machine family	Geometry and tooth form chosen for aluminum chip flow and surface finish	Qualitative — confirm with LIZEN
Lubrication / coolant note	Wet cold-saw processes often use coolant; follow machine and blade guidance	Lubrication / mist practices often differ; follow machine guidance	Qualitative — confirm; no mixture % published here
Category link	Metal circular / TCT cold saw · TCT cold saw blades	Aluminum saw blades	Live category pages
Life / tooth ranges	Not published as universal tables on this page	Not published as universal tables on this page	Confirm with LIZEN; controlled sample test

When aluminum-specific geometry matters

Aluminum profiles can stick to tips, leave poor finish, or chip differently from steel. If surface quality and chip adhesion matter, start from the aluminum path. Confirm with machine model, application data, and a controlled sample test.

Do not swap steel and aluminum blades casually

A steel-capable blade is not automatically right for aluminum profiles. Send the alloy family and section (or wall thickness) with the RFQ so LIZEN can point to the correct series.

Machine match: RPM, flanges, coolant, clamping, feed

Blade selection and machine setup travel together. Wrong speed, weak clamping, missing coolant, or worn flanges show up as vibration, burr, and tip chipping — often blamed on the blade first.

Match flanges and pin drive; check runout and clamping before raising feed.
Follow the machine’s RPM / surface speed and feed guidance; LIZEN does not publish a public RPM chart here.
Many TCT / cold-saw processes run wet; follow machine and blade guidance. Do not copy competitor mixture % as LIZEN advice.

FAQ: metal circular / TCT cold saw blades

What information do I need to quote a metal circular saw blade?

Send diameter, bore, kerf (and plate thickness if known), tooth count, material, machine model, quantity, and destination country. A photo of the current blade marking and pin-hole side speeds the match. Use the RFQ form, WhatsApp +86 131 7575 3620, or sales@lizensaw.com.

What does TCT mean on a cold saw blade?

TCT means tungsten carbide tipped: carbide tips on a steel blade body for industrial metal circular cutting. Tip grade and geometry are confirmed per application with LIZEN — this page does not invent tip grades or cermet claims.

How do I choose diameter and bore?

Read diameter and bore from the machine nameplate, the model sheet, or the blade you run today. Diameter must stay within machine capacity; bore and pin holes must match the arbor and flange exactly. Do not improvise adapters.

What is kerf on a circular saw blade?

Kerf is the cutting width of the blade — the material removed in one pass. Specs often list kerf together with plate (body) thickness as kerf/plate. Send both if marked; confirm available combinations with LIZEN for your machine.

Aluminum vs steel circular saw blade — what’s different?

Geometry, tooth form/count, and often lubrication or speed expectations differ. Use aluminum blades for profiles and extrusions when surface finish and chip control matter; use TCT cold-saw blades for steel and stainless on cold-saw style machines. Confirm with machine model, application data, and a controlled sample test.

How many teeth should a cold saw / TCT blade have?

Tooth count depends on diameter, material, and whether the section is solid or tube/thin-wall. Send section size and wall thickness with the RFQ. LIZEN does not publish a universal tooth chart on this page.

Why does a circular saw blade vibrate?

Common causes are wrong blade match (bore, pins, geometry), poor clamping, worn flanges or machine parts, unsuitable feed, or tooth geometry that does not suit the section. Check fit and clamping first, then feed and coolant.

Do I need coolant for TCT / cold saw cutting?

Often yes for wet cold-saw processes. Follow the machine builder’s and blade guidance for your setup. This page does not publish coolant mixture percentages.

Send one blade specification

You do not need a full catalog. Send diameter × bore × kerf × tooth count for the blade you buy today, plus material, section/wall, machine model, quantity, and country. Nameplate and blade photos help.
