1/8" Up-Cut Bit — Fast Chip Clearing on Deep Small-Diameter Cuts

Deep slots and pockets clog fast with the wrong flute geometry. This 1/8" up-cut bit lifts chips away from the workpiece, preventing chip recutting and heat buildup — even at this small diameter.

Solid carbide construction delivers clean, accurate cuts with sharp edges on wood, composites, and plastics.

Specs

Best for deep small-diameter slotting where chip clearing matters most.

What is a 1/8″ up-cut bit best for?

Deep slots and pockets at small diameters. It lifts chips away from the workpiece, preventing chip recutting and heat buildup.

What speeds and feeds should I use?

Start at 18,000 rpm, 60 ipm feed and 35 ipm plunge.

What materials can I cut?

Wood, composites and plastics.

When should I choose an up-cut over a down-cut?

Choose an up-cut when chip clearing matters most, like deep slots. Choose a down-cut when you need the cleanest top surface.

What are its dimensions?

1/8″ cutting diameter and shank, 0.75″ cut length and 1.6″ overall length, in 100% carbide.
