SpeTool 1/8 Inch Spiral Downcut Router Bit – 1/4 Inch Shank, 3 Inch Length, Extra Long Life Coating

SpeTool 1/8 Inch Spiral Downcut Router Bit with 1/4 Inch Shank

This SpeTool downcut router bit is designed for precise, controlled cutting across a range of woods. Its 1/8 inch cutting diameter pairs with a 1/4 inch shank and a full 3 inch overall length, giving you stable handling on standard 1/4 inch collet routers. The bit’s geometry is crafted to produce clean grooves and smooth top surfaces, making it a versatile choice for detailed work and edge finishing.

From softwood to hardwood and from plywood to laminate, this bit is built to perform with consistency. The spiral downcut design helps pull chips away and minimizes tear-out at the surface, yielding a neat, ready-to-finish edge in a single pass whenever possible.
