Key Features
Built for Abrasive Sheet Goods This Festool Diamond circular saw blade DIA 168×1,8×20 TD28 LAMINATE/HPL is made for materials that wear out standard blades fast, including laminate, high pressure laminate, fiber cement, and cement-bonded boards. 28 Diamond-Tipped Teeth The 28-tooth trapezoidal roof tooth design uses high-quality polycrystalline diamond teeth to hold cutting quality longer and reduce blade changes during heavy production work. Longer Service Life Festool states this blade can deliver up to 15 times longer service life than conventional carbide blades, which matters when you are cutting hard panels all day and do not want downtime.
Overview
The Festool Diamond circular saw blade DIA 168×1,8×20 TD28 LAMINATE/HPL is a 168 mm diamond-tipped circular saw blade for cutting hard, abrasive sheet materials. This is a circular saw blade designed for clean, durable cutting in laminate, high pressure laminate, compact boards, fiber cement, cement-bonded boards, gypsum-bonded boards, and solid surface materials. Model Number 578700. If you regularly ruin standard carbide blades on these materials, this is the upgrade that makes sense.
What sets this blade apart is the tooth construction. Festool uses 28 diamond-tipped teeth made from polycrystalline diamond, combined with a trapezoidal roof tooth profile. In practical terms, that means the edge holds up far longer in materials that are rough on conventional blades. Festool specifically calls out up to 15 times longer service life compared to standard carbide blades. That is not just about blade longevity. It also means more consistent cut quality and fewer interruptions to swap blades in the middle of a job.
The dimensions are aimed at precise plunge-cut and circular saw work where fit matters. This blade has a 168 mm diameter, 1.80 mm cutting width, 20 mm arbor hole, and 1.20 mm standard blade thickness. The 10 degree chip angle and 10 degree relief angle support controlled cutting performance in brittle and abrasive materials where a poor blade choice can chip edges, burn through teeth, or wander in the cut.
For cabinet installers, finish carpenters, façade crews, remodelers, and fabricators working with decorative panels or cement-based boards, this kind of blade earns its keep quickly. Laminate and high pressure laminate are notorious for eating up lesser blades. Fiber cement and similar board products are even worse. This blade is built for that exact kind of work, so you can keep making accurate cuts without sacrificing finish quality or constantly reaching for a replacement.
Festool also makes identification easier with color coding, which helps when you keep multiple blades around for different materials. That sounds small, but on a busy truck or in a shop with several saw setups, grabbing the right blade quickly saves mistakes. And with a blade made specifically for abrasive cutting, matching the right accessory to the material is a big part of getting clean results and protecting your saw from unnecessary strain.
If your work involves laminate countertops, decorative panels, compact boards, cementitious cladding, or other abrasive materials, this is the kind of specialized cutting accessory worth buying once instead of replacing cheaper blades over and over. It is not a general-purpose wood blade, and that is the whole point. It is for users who know exactly what hard sheet goods can do to ordinary teeth and want a blade built to handle it.
Made for Materials That Destroy Standard Blades
This blade is built for abrasive cutting jobs where ordinary carbide teeth wear out fast. If you cut laminate, high pressure laminate, fiber cement, or cement-bonded panels, the right blade is the difference between steady production and constant blade changes.
- 28 polycrystalline diamond-tipped teeth for extended cutting life
- Designed for laminate, HPL, CPL, compact boards, fiber cement, gypsum-bonded boards, and solid surface materials
