MILWAUKEE® Track Saw Blades are designed to deliver accuracy and finish quality cuts in all Track Saw applications. The 4T Fibre Cement specialty blade has Polycrystalline Diamond (PCD) teeth for up to 75X longer life vs standard blades when cutting fibre cement materials. The low tooth count and large gullet design also help to produce less dust for a healthier jobsite environment. Its laser-cut, resin-filled vibration slots absorb vibrations and reduce wobble for increased accuracy. An anti-friction PTFE coating protects the blade against heat and friction for cooler, smoother cutting.
