CMT ORANGE TOOLS 230.312.08 DADO Set Saw Blade HW D=8” B=5/8” Z12

The CMT ORANGE TOOLS 230.312.08 is an 8-inch dado saw blade set designed for woodworkers cutting flat bottom grooves in solid wood, veneer plywood, melamines, and laminates. It addresses the common frustration of tear-out and uneven joint bottoms by combining a FTG+ATB tooth geometry with a negative 12-degree hook angle. Built to fit machines with a 5/8-inch arbor, this set provides a reliable solution for clean joinery across delicate sheet goods and hardwoods alike.

A standout element of this set is its compliance with the UNI EN847 standard. Thanks to a specialized blade body design and dedicated plastic lock spacers, the assembled parts never touch each other while the blade is spinning. To fine-tune the width of your cuts, the package includes both plastic and magnetic shims alongside the lock spacers, allowing for micro-thin adjustments so you can match the exact thickness of your workpieces.

Durability and ease of maintenance are supported by the trademark Orange Shield coating. This layer protects the blade components against heat, resin gumming, and corrosion during heavy cutting tasks. With a 12-tooth configuration (Z12), the tooling is engineered to yield virtually splinter-free edges without requiring extensive cleanup on finished veneers or laminated boards.

As for trade-offs, this set is sized specifically with an 8-inch diameter and a 5/8-inch bore, meaning it will not fit saws requiring larger arbors or different bore diameters. Woodworkers should also note the specific negative 12-degree hook angle and 12-tooth count, which define its cutting profile and feed characteristics.

Verdict: The CMT ORANGE TOOLS 230.312.08 Dado Set is an ideal choice for woodworkers who need clean, flat bottom joinery in sheet goods and solid timber. If your saw accepts an 8-inch blade with a 5/8-inch bore and you value precise shimming options, this set is well worth adding to your shop.
