Great upgrade for older lathes

Combined with the AXA QC tool holder, this set is a real insider tip. This is a definite improvement over 1/4" HSS bits held in a lantern holder. The plates must be pressed down firmly before use, but the plates themselves are usable. The boring bar has flat surfaces for use in a traditional holder, eliminating the need for a dedicated boring bar holder.

Pros
  • Each tool holder comes with positive rake carbide insert and built in chip breaker, ideal for general purpose cutting.
Cons
  • Drill package

Not 1/2 ". Magnetised and holding chips.

They are not 1/2" but 12mm and should be sold as such. Good otherwise, but annoying when switching from other tools, they are almost 0.030 inches lower. I would return them but I had to use them so now I have them I will adjust them. Edit February 29, 2020: I didn't realize this until I started cutting - they're magnetized. All of them. They are covered in chips. I checked everything with a compass, the boring bar is ok, the remaining holders are magnetized, I haven't been able to demagnetize…

Pros
  • Black oxidised smooth finish for any type of turning tool holder and shank size.
Cons
  • Quick Start Guide

Almost a good product.

First, I like how it works. This is a chip breaking on metals that CNMG and WNMG had problems with. It was just long curls, and those are real chips. 4 came, the drill rod surprised me with a negative rake. The rest have a neutral edge. 2 out of 4 had the carbide not seated evenly. I contacted the seller and he said he would send me 2 new ones if I provided the address. But I decided to try to fix the holders. The screw did not match the carbide. I put the bag back and now it sits flat. Problem

Pros
  • blades fine workmanship, high strength, high strength, stability and durability. If you need more dcmt21.51 inserts, you can search for Asin: B07GSW3VSG
Cons
  • Big and bulky
