Fantastic Countersink Bit

The Saiper Combination Countersink Plastic Aluminum bit worked very well for me.based on my experience it’s one of the best countersink bits that I’ve ever used. The bit met my expectations and worked great on a variety of materials like plastic and aluminum. It has a sharp and durable design, which makes it ideal for heavy-duty use. The only con is that it CANNOT be used on harder metals such as steel. Overall, i recommend this bit for anyone who needs a reliable and durable countersink bit..

Pros
  • Sharp, durable design, works great on plastic and aluminum
Cons
  • Cannot be used on harder metals like steel

Work really well! fits drill machine parts and accessories

I didn't know what to expect from them. So much so that I immediately bought the standard set as a backup. You really impressed me. Much easier than drilling and tapping separately. Once I drilled the hole, I slowed down until I felt the rooster "bite," then slowly followed. It was fun! Very glad I bought them!

Pros
  • Stylish and modern design
Cons
  • Slightly wrinkled
