Low Quality Ballnose bit

Low Quality Ballnose bit

Postby Rcnewcomb » Tue Aug 14, 2018 4:42 pm

As some of you may recall, I like to try out various bits and occasionally have found some great values.

This is not one of those times.

I saw "10Pcs 3.175mm 1/8" Double Flute Spiral Cutter CNC Router Bits 17mm US Shipping" with free shipping for $9.65, i.e. $0.97 per bit.

The first bit broke while I was putting it in the collet.
The second bit lasted about 3 passes at the edge of a dish carving.

I'll try them in my Dremel, but for CNC use they are about the same as putting a pretzel in the collet. :shock:

YMMV

I still find that www.Cuttingtoolsource.com has the best spiral bits for the money... they are made for metal working, solid carbide, and though may be a bit more expensive than some, but worth the price. They also offer resharpening but because of freight only pays if you send several bits. I use 3-flute spirals only. 4-flute bits burn burn burn when used in wood. Dale
