SpeTool Extra Long O Flute Spiral Router Bits 1-1/2 Inch Cutting - CNC End Mill For Aluminum & Plastic

CNC enthusiasts and woodworkers, meet your new favorite router bit!

This SpeTool O Flute spiral end mill features an extra-long 1-1/2 inch cutting length that's perfect for deep carving and milling operations.

The unique O-flute design is what really sets this bit apart - it provides efficient chip removal that reduces clogging and gives you smoother cuts in soft materials.

Made from solid carbide, this bit maintains its sharpness through extensive use on tough materials.

The single-flute upcut design is ideal for aluminum, acrylic, PVC, MDF, copper, and wood - materials that can be tricky with conventional bits.

The 1/4-inch shank fits most routers and CNC machines with 1/4-inch collets, while the 3-inch overall length provides plenty of clearance.

When working with acrylic, the O-flute leaves remarkably clean edges without the melting or chipping you often get with other bits.

For aluminum, the single flute design helps manage heat buildup and prevents material welding to the bit.

The upcut spiral efficiently pulls chips out of deep cuts, giving you cleaner results throughout the entire cutting depth.

Perfect for sign making, decorative carving, precision parts, and hobby projects where clean finishes matter.

The long cutting length means you can make deeper passes in a single operation, saving time on multi-pass projects.

SpeTool specializes in cutting tools, so you're getting professional-grade quality without the professional price tag.

The carbide construction holds up better than high-speed steel, especially on abrasive materials like composites or hardwoods.

The precise manufacturing ensures consistent performance bit after bit.

Great for CNC routers where tool quality directly impacts your final product quality.

The O-flute geometry really shines on plastics and non-ferrous metals where clean edges are crucial.

Much better chip evacuation than straight flute bits, which means less heat buildup and longer tool life.

Whether you're a professional machinist or serious hobbyist, this bit delivers results that will impress.

The single flute design allows for larger chip pockets, making it ideal for materials that produce bigger chips.

No more struggling with bits that clog or leave rough finishes on your precious projects.

The value becomes obvious after your first use - cleaner cuts, less sanding, and longer tool life.

One of those tools that once you try, you'll wonder how you managed without it!

Keep several on hand for when projects call for deep, clean cuts in challenging materials.
