1/2″ Down-Cut Spiral Bit – 1″ LOC *Astra Coated*

The flutes are designed to push the chips downward and they also help with fraying and chipping on your work piece.

  • Astra Coated
  • Solid Carbide
  • 1/2″ Tip diameter
  • 1″ Length of cut
  • 1/2″ x 3″ – Overall Tool Size
  • Made In USA

These tools are coated with a proprietary high performance *Astra coating* that allows higher speed & feed rates as well as 2x the extended tool life & increased lubricity in abrasive material

Jonathan's Hot Take:

Downcut spiral bits are my most used bit when I want a clean edge on the tool-side of my stock.

They're great for stopped mortises, grooves, and dados — and also for hogging out material on the CNC.

These bits provide the HIGHEST VALUE because the Astra Coating makes them last at least 2-4x longer than uncoated bits. This is one of those times that spending a little more upfront saves you a lot of money down the line.

Spiral bits perform 100x better and 100x longer than straight bits. I recommend staying away from straight bits in general, because they dull so much faster and their aggressive cutting profile can be much less safe.

What is a DownCut bit?

With a DownCut bit, the advantage is that it’s pushing down on the piece you’re working on, plus it cleanly cuts the top surface. The tradeoff is the waste is pushed back into the cut area instead of being ejected, so we recommend not to cut dados or drill holes with a downcut. These bits are also made to be used slower – both in revolution or RPM of the bit, and also in spindle movement. That’s because the waste often has nowhere to go, so it is continually being chopped by the sharp flutes.
