FAQ

What is the 400mm TCT saw blade (4.4/3.2mm kerf, 60/75mm ID, laser‑weld) typically used for?

This blade is a tungsten‑carbide‑tipped (TCT) circular saw blade sized for industrial and professional woodworking. It’s best for cutting solid timber, veneered panels, plywood, MDF, melamine, laminates and many wood‑based composites. It can be used for crosscutting, ripping and panel sizing depending on the tooth geometry (fine teeth for clean crosscuts, fewer teeth for faster ripping). For non‑ferrous metals or plastics, check the blade’s specific rating with the manufacturer before use.

What do the numbers “4.4/3.2mm kerf” mean and how do they affect cutting?

The two numbers refer to blade body/kerf dimensions: one is the plate thickness and the other the actual cut width (kerf). A wider kerf (more material removed) generally improves blade stability and reduces vibration, producing straighter cuts, but it requires more power from the saw and creates more waste. A thinner kerf saves material and demands less motor power but can be more prone to deflection. Choose based on your saw’s power and the finish/accuracy you need.

Which saws and arbors will this blade fit? What does 60/75mm ID mean?

The “60/75mm ID” indicates the blade bore and the common reducer sizes it supports—typically a larger center hole with included rings or adapters to fit either a 60 mm or 75 mm arbor. A 400 mm blade with these bushings commonly fits panel saws, sliding table saws, heavy duty jobsite and some cabinet/table saws that accept that diameter and arbor size. Always confirm your machine’s arbor diameter and maximum blade diameter, and ensure the blade’s stamped maximum RPM matches or exceeds the machine speed.

What are the benefits of laser‑welded construction versus brazed or pressed teeth?

Laser welding bonds the carbide tips to the steel body with a precision weld that provides excellent mechanical strength and heat resistance. Benefits include better tip retention under heavy or intermittent loads, improved durability when cutting abrasive materials, reduced risk of tooth loss at high temperatures, and typically better runout stability. Laser welding is especially advantageous in demanding industrial applications where stability and long life are important.

What operating speeds, feed rates and setup tips should I follow for best results?

Always follow the blade’s stamped maximum RPM and your machine’s limits. For a 400 mm blade typical peripheral speeds fall in the range that corresponds to roughly 3,200–4,800 RPM depending on the saw and recommended cut speed; check the blade label. Feed per tooth (chip load) depends on material and tooth geometry—typical ranges for wood are around 0.05–0.25 mm per tooth: lower for fine finishing cuts, higher for ripping. Use correct blade orientation, solid top and back flanges, a riving knife or splitter to prevent kickback, and hold material firmly or use proper fences and push devices. For veneered or laminated surfaces, use an anti‑tear or scoring blade or a blade with a high tooth count to minimize chipping.

How do I maintain, resharpen and store the blade safely?

Keep the blade clean of pitch and resin build‑up to maintain cut quality and reduce heat. Carbide tips can be reground by a qualified service to restore geometry—do not attempt to regrind tips without the right equipment. Inspect for cracked tips, missing teeth or excessive runout; replace the blade if damage is found. Store blades flat or hung on a peg to avoid bending. Always disconnect power and follow lockout procedures when installing or removing the blade, use proper blade washers/flanges, and wear appropriate PPE (eye, hearing and cut‑resistant gloves where required).
