4" (105mm) TCT 30T Saw Blade, Carbide Tip, Steel

Short description:

A compact 4" (105 mm) TCT saw blade with 30 tungsten‑carbide‑tipped teeth built for durability and cleaner cuts. The 30T tooth count gives a balance of cutting speed and finish, while carbide tips keep edge life long on metal and mixed materials. Designed for small circular saws and portable cutters, it’s a handy blade for precision trimming and light fabrication.

Usage scenarios (about 3 sentences):

Use it to cut thin‑gauge steel sheets, metal studs, conduit and small HVAC or electrical trim work where a compact saw is needed. It also works well on aluminum and other non‑ferrous metals and can handle occasional cuts in plywood or laminates for mixed‑material jobs. Ideal for DIY metal repairs, light fabrication, and on‑site trimming with a 4" handheld circular saw—always clamp work securely, run at recommended speed, and wear proper PPE.

FAQ

What materials can a 4" (105mm) TCT 30T carbide‑tipped blade cut?

A 30‑tooth TCT blade is primarily designed for woodworking—clean crosscuts and general purpose cutting of solid wood, plywood, MDF, particleboard and laminated panels. It can also handle plastics and thin non‑ferrous metals (aluminum, brass) if the blade is specifically rated for metal. It is not recommended for cutting thick ferrous steel or reinforced concrete unless the manufacturer explicitly states a steel‑cutting application.

Which saws and arbor sizes is this 105mm blade compatible with?

This blade fits compact 4" (105mm) circular saws, mini chop/miter saws, small table saws and plunge saws that accept 105mm blades. Check your saw’s arbor diameter—common small‑blade arbors are 5/8" (16mm) or 20mm—and use the correct reducer or flange if needed. Always confirm compatibility with your saw manual before mounting.

What speed and feed practices give the best results with a 30T TCT blade?

Follow the blade’s marked maximum RPM and your saw manufacturer’s recommendations—do not exceed the blade’s rated speed. For wood and laminates use a steady, moderate feed rate to avoid burning or chipping; too slow causes burning, too fast causes tear‑out or blade stress. If cutting non‑ferrous metal, use lower speed, a light steady feed, and appropriate lubrication or coolant when recommended.

How should I install the blade to ensure safe and correct operation?

Before installation, disconnect power. Verify the blade’s rotation arrow matches the saw’s rotation direction. Clean hub and flange faces, place the blade snugly against the flange, and torque the arbor nut to the saw manufacturer’s specifications. Reinstall guards and check blade runout by rotating by hand; there should be minimal wobble.

How do I maintain the blade and extend its life?

Keep the blade clean of pitch and resin with appropriate cleaners, avoid cutting materials that will abrade or chip the carbide (e.g., masonry, nails), and use the correct blade for the material to prevent overheating. Carbide tips can be professionally re‑tipped or reground when worn, but replacement is often the practical option for low‑cost blades. Store blades flat and dry to avoid damage.

What safety signs indicate the blade should be replaced, and what PPE should I use?

Replace the blade if you notice missing or severely chipped teeth, humming or vibration during cutting, frequent burning of cut surfaces despite correct technique, or reduced cutting performance. Always wear eye protection, hearing protection, and a dust mask or respirator when cutting; use push sticks or fences for small pieces, ensure guards are in place, and never force the blade through a cut.
