Freud 12-100: 1/4in Double Flute Straight Bit with 1/2in Shank – Eclipse Grind for Precision Routing

Overview

The Freud 12-100 1/4in double flute straight bit is engineered for precision routing across a variety of materials. With a 1/2in shank and a compact 2-3/8in overall length, it pairs well with CNC routers, handheld units, and table-mounted machines for smooth, controlled cuts that feel precise from start to finish.

Why this bit stands out

• Specs: two cutters, overall diameter 1/4in, overall length 2-3/8in, shank diameter 1/2in, carbide height 3/4in
• Tico Hi-Density Carbide for long-lasting sharpness and consistent performance
• Clean cuts in solid wood, plywood and composites with a reliable finish
• Designed for use in CNC, handheld and table-mounted routers for versatile workflow

Real-world use cases

Ideal for precision grooves, edge routing, and general routing tasks. The Eclipse Grind supports smooth plunge cuts and clean entry points, while the double flute design helps deliver controlled cuts with reduced tearing when working across various woods and composites.

Materials and finishes

• Works well with hardwood and softwood, offering steady, crisp edges
• Performs reliably on plywood and composite materials for consistent results
• Produces a smooth surface with minimal burnish when used at appropriate speeds

Tips for best results

Operate up to 24,000 RPM and choose an appropriate feed rate for the material and cut depth. Start with shallow passes on scrap stock to dial in speed and depth, then progress gradually to finish passes that preserve edge quality.

Durability and care

Crafted with TiCo Hi-Density Carbide, this bit is designed to hold its edge longer between sharpenings, helping minimize downtime. Regular cleaning and proper storage extend tool life and maintain cut quality.
