Question 1

What circular saw blade should I use for cutting wood?

Accepted Answer

Circular saw blades for wood typically use tungsten carbide tipped (TCT) teeth designed for fast cutting and clean finishes. Lower tooth counts are ideal for ripping timber quickly, while higher tooth counts produce smoother cuts when cutting plywood, MDF, laminate or engineered boards.

Question 2

What circular saw blade should I use for cutting metal?

Accepted Answer

Metal cutting circular saw blades are designed to cut aluminium, steel and other metals safely. These blades use specialised tooth geometry and carbide tips to handle harder materials. Always use a blade specifically rated for metal when cutting steel or non-ferrous metals.

Question 3

Can circular saw blades cut plastic?

Accepted Answer

Yes, circular saw blades can cut many plastics including PVC, acrylic and composite panels. Fine-tooth blades or specialised plastic cutting blades help reduce chipping and melting while producing cleaner edges.

Question 4

What is a carbide circular saw blade?

Accepted Answer

A carbide circular saw blade uses tungsten carbide tips attached to the steel blade body. These tips stay sharp longer than standard steel blades and provide improved durability when cutting wood, laminate, plastics and composite materials.

Question 5

What size circular saw blade do I need?

Accepted Answer

Common circular saw blade sizes include 125 mm, 150 mm, 165 mm and 180 mm. The correct size depends on your saw model and arbor size. Always check your tool’s manual to ensure the blade diameter and bore size match your saw.

Question 6

What circular saw blade should I use for metal or wood?

Accepted Answer

Different blades are designed for different materials. Wood cutting blades typically have more aggressive tooth shapes for timber, while metal cutting blades use stronger tooth designs for aluminium or steel. Using the correct blade improves performance and extends blade life.
