1/8" Long-Cut Down-Cut Spiral Bit — Extra Reach, Same Clean Top Surface

Standard-length 1/8" bits run out of depth on thicker material. This long-cut version pulls chips downward for a splinter-free top surface while giving you extra length of cut to handle deeper slotting and profiling.

Solid carbide construction stays sharp through high-volume runs, whether you're cutting one board or fifty.

Specs
  • Cut diameter: 1/8″
  • Shank: 1/8″
  • Length: 2.25″
  • Cut length: 1.5″
  • Material: 100% carbide
Settings
  • Speed (rpm): 18,000
  • Feed: 60 ipm
  • Plunge: 35 ipm

Best for deeper cuts where a standard-length 1/8" bit falls short.

What is a long-cut 1/8″ down-cut bit for?

Deeper slotting and profiling in thicker material, with a splinter-free top surface.

What speeds and feeds should I use?

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

How much longer is the cut than the standard 1/8″ down-cut?

This one has a 1.5″ cut length on a 2.25″ overall length. The standard 1/8″ down-cut has a 0.75″ cut length.

What collet size does it need?

A 1/8″ collet. Cutting diameter and shank are both 1/8″.

Will it hold up in production?

Solid carbide construction stays sharp through high-volume runs, whether you're cutting one board or fifty.
