What specifications are most important when buying a TCT saw blade?

For industrial metal cutting, start with OD, bore, kerf, tooth count, material application, maximum RPM, tooth geometry, coating and carbide grade. Then match these to the machine, material section and production target.

Can two TCT blades with the same diameter and tooth count perform differently?

Yes. Tooth grind, hook angle, carbide grade, coating, plate design, runout control and application rating can make two blades behave very differently even when OD and teeth are the same.

Is a TCT saw blade specification enough for a quotation?

It is a starting point, but a good quotation also needs material grade, workpiece dimensions, saw model, RPM, coolant or dry cutting condition, current blade life and the main cutting problem.

Complete Guide to TCT Saw Blade Specifications: OD, Kerf, Bore, Teeth, Hook Angle, Coating and Carbide Grade

A complete industrial glossary for TCT saw blade specifications, explaining OD, kerf, bore, tooth count, hook angle, coating, carbide grade and how to match a blade to metal cutting applications.

Focus keyword: TCT saw blade specifications

Secondary keywords: TCT circular saw blade specifications, saw blade OD kerf bore tooth count, carbide tipped saw blade specification, metal cutting saw blade specs

Search intent: A buyer, distributor or production engineer needs to understand TCT saw blade parameters before choosing or requesting a quotation.

Practical takeaway:

TCT saw blade specifications are not just catalog numbers. OD, bore, kerf, tooth count, hook angle, coating and carbide grade must be matched to the saw machine, material, workpiece shape, wall thickness, RPM, feed and cut-quality target.

Why TCT saw blade specifications matter

A TCT saw blade is a tungsten carbide tipped circular saw blade. In metal cutting, it is usually purchased by specification: outside diameter, bore, kerf, tooth count, maximum RPM, material application and sometimes coating or carbide grade.

The problem is that many buyers read the number line on the blade but do not understand how each specification affects cutting. A blade marked 355 x 25.4 x 90T may look simple, but it still does not tell you whether it is right for stainless tube, carbon steel profile, solid bar or thin sheet unless the tooth geometry, kerf, coating, RPM and application rating are also known.

Good suppliers read TCT saw blade specifications as a system. The blade must fit the machine mechanically, cut the material safely and produce the required cut quality at a realistic cost per cut.

TCT saw blade specification glossary

Specification	What it means	Why it matters in metal cutting
OD / outside diameter	The full blade diameter, usually shown in mm or inches.	Controls machine fit, cutting depth, surface speed and the correct RPM range.
Bore / arbor hole	The center hole that mounts on the saw spindle.	Must match the machine arbor. A wrong bore creates unsafe mounting and runout risk.
Kerf	The width of cut made by the tooth tips.	Affects material loss, cutting force, chip volume, heat and machine load.
Plate thickness	The steel body thickness behind the carbide tips.	Works together with kerf to control stiffness, clearance and stability.
Tooth count / Z	The number of teeth around the blade.	Controls chip load, burr tendency, heat, feed feel and the number of teeth engaged in the workpiece.
Hook angle / rake angle	The angle of the tooth face relative to the blade radius.	Controls how aggressively the tooth enters the material and whether the cut feels stable or grabby.
Tooth geometry	The grind form, such as TCG or other metal-cutting grinds.	Determines edge strength, chip formation, surface finish and durability.
Coating	A surface treatment such as TiN, PVD or application-specific coating.	Reduces friction, helps chip flow and improves heat and wear resistance in suitable applications.
Carbide grade	The carbide tip material selected for toughness, wear resistance and heat resistance.	Affects edge life, chipping resistance and performance on steel, stainless steel or abrasive materials.

Practical reading

A blade specification is not a recommendation by itself. The same OD, bore and tooth count can be correct for one saw and wrong for another if RPM, material, wall thickness, clamping or coolant are different.

Real public specification examples

Published example	What the specification shows	Buyer lesson
Evolution 355 mm 90T thin steel TCT blade	The product is described with 355 mm diameter, 90 teeth, 25.4 mm bore and a narrow kerf.	Diameter, bore and teeth appear in the product name because they are the first fit-check buyers make.
DRYTECH TCT metal cutting table	The table lists OD, bore, kerf, teeth and application, including steel, thin steel and steel-stainless combinations.	Industrial blade catalogs usually separate application by material and section, not by diameter alone.
LENOX metal cutting circular saw blade	The blade is carbide tipped and titanium nitride coated for metal cutting.	Coating and tip material are selling points because build-up, heat and burrs are real buyer concerns.
Kinkelder TCT solid stationary blades	Selection is described through body design, tooth design, tooth material and coating.	Production cutting requires a system match, especially for solid steel bars and dense materials.

How to read a TCT saw blade specification before buying

Confirm the saw machine accepts the blade OD and bore.
Check maximum RPM against machine RPM and blade diameter.
Confirm kerf and plate thickness are suitable for machine power and cut stability.
Select tooth count by workpiece section, not by habit.
Match hook angle and tooth geometry to material and feed style.
Choose coating and carbide grade according to heat, wear, stainless content and production volume.
Ask for a starting cutting condition rather than only a price.
