The Freud 04-152 1-Inch Double Flute Straight Router Bit is a carbide-tipped straight router bit for general-purpose routing work. This is a straight router bit designed for grooving, edge-routing, and plunge routing in wood and composite sheet goods. Model Number 04-152 uses a 1/4 inch shank, a 1 inch cutting diameter, and a 3/4 inch carbide height, which makes it a good fit when you need a wider straight cut from a compact-shank bit.

Where this bit earns its keep is in day-to-day shop work. The double flute design gives you two cutting edges working through the material, and Freud calls out precise hook and shear angles to help the bit cut quickly while leaving a smoother finish than a basic straight cutter. In practical terms, that means cleaner grooves in plywood, better edge-routing results in hardwood and softwood, and more predictable stock removal when you are cutting dados, channels, or recesses.

The relieved end geometry matters too. Freud designed this bit so it can plunge efficiently, which is a real advantage when the cut starts away from the edge of the board. If you are dropping into a panel for a stopped groove or routing a pocket on a CNC, that detail saves time and helps the bit enter the cut more cleanly instead of forcing the tool to fight its way in.

Material choice is one of the strong points here. The carbide-tipped cutting edges use Freud Tico Hi-Density Carbide, and the bit is intended for solid wood, plywood, and composites. Supplementary product data also points to clean cutting in MDF, particle board, OSB, laminate, cellular PVC, and composite decking. That makes this a practical bit to keep around if your work moves between hardwood trim, cabinet parts, veneered panels, and common jobsite sheet goods.

For shop setup, the 04-152 is built to work in CNC machines, hand-held routers, and table-mounted portable routers. The 1/4 inch shank gives it wide compatibility with routers that accept that collet size, while the 2 inch overall length keeps the profile straightforward and easy to control. The listed maximum speed is 24,000 RPM, so it is suitable for the normal operating range of many trim routers and router tables when matched correctly to the cut and material.

This bit is best for woodworkers, cabinet installers, trim carpenters, remodelers, and serious DIY users who want a wider straight bit for grooves and edge work without stepping into a specialty cutter. If most of your jobs involve clean straight routing in plywood, hardwood, softwood, or composites, the Freud 04-152 gives you a solid balance of cut quality, plunge capability, and router compatibility.
