1/8" Shank Surfacing Bit for Desktop CNC Routers, 3/4" Ultra-Smooth Cut

The only 1/8” Shank CNC Surfacing Bit designed specifically for desktop CNC routers.

This 3/4” cut diameter CNC surfacing bit is part of the Ultra-Smooth Cutting Series from IDC Woodcraft, designed to deliver cleaner cuts, faster feed rates, and longer tool life — helping you create perfectly surfaced spoilboards, slabs, and project materials — even on compact CNC machines like the 3018. Whether you're resurfacing your CNC spoilboard (also called a waste board or spoiler board), flattening slabs, or cleaning up warped project materials, this is an essential tool for desktop CNC owners.

Why is this bit better?

Unlike standard surfacing bits, this is the only 1/8” shank CNC surfacing bit on the market. It was developed to meet the demand from desktop CNC users who cannot find a proper surfacing solution for their smaller machines.

This bit features the same Ultra-Smooth Cut 4-flute design as our full-size surfacing bits, providing:

• Higher feed rates without sacrificing cut quality
• Longer tool life thanks to reduced cutting friction
• Superior surface finish — ideal for spoilboards, slabs, and project surfaces

Designed for desktop and small benchtop CNC users:

This 3/4” CNC surfacing bit is made specifically for desktop CNC routers with a 1/8” collet — including the popular 3018 series. It allows effective cleanup and surfacing in one pass, even at higher feed rates, making spoilboard preparation and slab flattening faster and more efficient.

Important: If your CNC uses a 1/4” collet, we recommend using our 1” or 1-1/2” Ultra-Smooth Cut Surfacing Bits for optimal results.

Fits all CNC routers with a 1/8” collet.

Applications:

• Spoilboard leveling and resurfacing
• Slab flattening
• Cleaning up warped or uneven project materials

A Note from Garrett (CEO of IDC Woodcraft)

I designed the Ultra-Smooth Cut Surfacing Bit Series because I was frustrated with the mediocre performance and short lifespan of surfacing bits typically sold on Amazon and by many CNC bit suppliers. Desktop CNC owners in particular had no option for a proper 1/8” shank surfacing bit — so I designed one! I’m proud to offer this bit to CNC creators who care about quality and getting the best results from their work — no matter what size machine they use.
