Disappointing Performance

The router bit presented a considerable disappointment. It is marketed as industrial and scientific but failed to perform even basic tasks. The only positive aspect was the size, which was appropriate for my project. Unfortunately, the con is that it did not meet my expectations and was a waste of money.

Pros
  • Straight design allows for easy and precise cuts.
Cons
  • Limited to 4 inch diameter materials.

No visible tarnishing

This is a great tool that cuts without noticeably dulling the cutting blades. Definitely recommended for active users.

Pros
  • For use on wood and wood composites.
Cons
  • weak

Premium knives

I have several brands of cutters that I like to use. SMT is at the top of my list, with Freud and Bosch at number 2 and 3. It seems that CMT makes a more durable carbide hole saw. While I've had good results and durability with Freud and Bosch tips, I tend to use CMT branded products a bit more. But you can see that I'm a pro fan of all three brands.

Pros
  • Smooth and precise cut. Exceptional chip control for cleaner, more consistent cuts.
Cons
  • Slightly torn
