SHARPRO O Flute Upcut Spiral Router Bit 1/4in Shank – 1/4in Cutting Dia, 2-1/4in OVL | Carbide CNC Router Bit for Aluminum, Plastic, Wood

Meet the SHARPRO O Flute Upcut Spiral Router Bit, a compact cutting solution designed to handle a range of materials with dependable control. Featuring a 1 inch cutting length, a 2-1/4 inch overall length, and a 1/4 inch shank, this carbide bit is ready for standard routers and CNC setups, offering consistent performance across repeated passes.

Why choose this bit

The upcut design paired with a 25 to 28 degree helix and a mirror-polished edge helps reduce sticking and improves surface quality. These attributes contribute to cleaner edges on plastics, acrylics, and wood, while preserving material integrity during routing.

Precision and efficiency

Thanks to a larger spiral chip space and tight manufacturing tolerances within ±0.02 mm, you may experience smoother cutting and faster chip evacuation, which is useful for longer runs and complex profiles.

Materials and compatibility

Designed for versatility, it works with popular handheld routers from BOSCH, DeWalt, Milwaukee, and with conventional CNC milling or engraving machines. This makes it a flexible option for mixed shop setups.

• Materials you can work with: aluminum, Plexiglass, plastic, acrylic, softwoods, solid wood, plywood, MDF, and PVC
• Applications include routing, profiling, edging, and light machining of panels and frames

Planet-friendly manufacturing

Sharpro emphasizes a climate pledge friendly, low-carbon production process, aiming to reduce waste and tool changes while delivering durable, high-speed machining potential.

Real-world use and expectations

In practice, you may notice crisp edges and smooth finishes across materials, aided by edge polish and the chip-space layout. As with any tool, results can vary by material, speed, and technique.
