Freud 1-3/8" Double Flute Straight Bit | 1/2" Shank

Part Number: 12-186

Series: Double Flute Straight (Carbide Tipped)

Product Overview The Freud 12-186 is a heavy-duty double flute straight router bit designed for rapid stock removal and precision surfacing. With a large 1-3/8 inch cutting diameter, this bit is ideal for planing, grooving, and cutting deep dadoes in a wide variety of materials.

Engineered with Freud’s exclusive TiCo™ High-Density Carbide, the 12-186 offers superior durability and a sharper edge that lasts longer than standard carbide bits. Its computer-balanced body and precision-ground shear angles ensure a smooth, burn-free finish, making it suitable for use in hand-held, table-mounted, and CNC routers.

Key Features & Benefits

  • TiCo™ High-Density Carbide: Manufactured with a specially formulated, highly compact Titanium Cobalt Carbide blend for maximum cutting life and flawless finish.

  • Double Flute Design: Two precision-ground cutting edges provide a balanced cut and efficient chip ejection, leaving a smoother surface than single-flute alternatives.

  • Shear & Hook Angles: Optimized cutting geometry produces clean, splinter-free cuts in hard-to-machine materials like composite and plywood.

  • End Relief: Tips are relieved to allow for efficient plunge cutting capabilities.

    Perma-SHIELD® Coating: Features Freud's non-stick red coating to reduce friction, heat buildup, and pitch accumulation (gumming).
