KREFELD - Spektra Extreme Tool Life Coated Spiral Plunge 1/4 Dia x 3/4 CH x 1/4 SHK 2-1/2 Inch Long Down-Cut Router Bit

Solid Carbide KREFELD™ Extreme Tool Life Coated Spiral Plunge Down-Cut Router Bits are crafted from a specialized, ultra-hard carbide with an advanced nACo® nanocomposite coating, designed for extended durability and precision cutting.

Optimized Cutting Performance

Spiral-flute bits combine a shearing action for clean, precise cuts with an augering action that efficiently clears chips. The Down-Cut design ensures a smooth surface finish, reducing chipping and tear-out.

Advanced Carbide & Coating Technology

Featuring a specialized carbide grade, these bits offer improved clearance geometry, razor-sharp cutting edges, and polished flutes for superior performance, especially in abrasive materials. The nACo nanocomposite coating enhances tool life and cutting efficiency by providing:

• Exceptional Edge Retention: A micro-thin ceramic coating maintains sharpness and reduces friction for cleaner cuts.
• Superior Heat & Oxidation Resistance: Protects the tool from heat damage, ensuring longevity.
• Long-Lasting Protection: The coating remains effective even after the multi-colored hue fades with use.
• Extreme Hardness: With a 4,500 Vickers rating, these bits are up to 2.5 times more durable than uncoated versions.

Ideal for CNC & Router Applications

These bits are designed for use in CNC machines, automatic routers, and handheld or table-mounted routers. They are excellent for creating grooves, dado cuts, and shelf pin holes, especially in System 32 cabinetry applications.
