New Bits

Postby loyd » Tue Jul 02, 2019 3:06 pm

I decided to try out the cheap carbide bits. The 1/8" shank bits came through Amazon. They were made by a Chinese company. There are 10 each of metric size 3.175 mm [which is equal to 1/8"] and 1.5mm which is 0.059" [1/16" is 0.0625] That's pretty close to what I use for the finishing tool path. The price for those was $12 and $13 respectively.

The 1/8" collet that I use is a precision one from Precise Bits.

The other bits in the picture are the cone shaped versions from Precision bits. I haven't looked lately, but I think I paid somewhat more than $25 each for those. The conic design is not as likely to break off as those new ones with the skinny necks and I'll need to do some feeds and speeds study to give them a chance so if anyone has a suggestion, please pass it on. My knowledge is zero at the moment and I hope it improves before I break all of these new bits.
