Micro-Detail 1/16" Down-Cut Spiral Bit — Precision Without the Fuzz

Small-diameter cuts are unforgiving — one wrong pass and you're sanding out fuzz for twenty minutes. The 1/16" Down-Cut Spiral Bit pulls chips down instead of up, keeping your top surface clean on even the tightest, most detailed carves.

Built from solid carbide, it holds its edge through the slow, careful passes fine detail work requires, so you're not swapping bits mid-project.

Results vary by material and machine rigidity — treat these as your starting point.

What is a 1/16″ down-cut spiral bit for?

Micro-detail carving where fuzz would ruin the job. It pulls chips down instead of up, keeping the top surface clean on tight, detailed carves.

What speeds and feeds should I use?

Start at 18,000 rpm, 20 ipm feed and 15 ipm plunge.

Why are the feeds so slow?

Small bits do their best work on slow, careful passes. Treat those numbers as your starting point and adjust for your material and machine.

What collet size does it need?

A 1/8″ collet. The 1/16″ cutting diameter sits on a 1/8″ shank, with a 2.25″ overall length.

How deep can it cut?

Cut length is 0.3″. If you need more reach, see the 1/16″ Long Cut Down-Cut Spiral at 0.5″.
