Efficient and Precise Drill Bit

This cutting tool is a game changer. Its carbide tip allows for clean and accurate holes perfect for industrial and scientific applications. The design reduces vibration, making drilling more efficient and less tiring. However, the size options may be limited for those with specific needs. Overall, this drill bit is a reliable and top-performing choice in the Industrial and Scientific community..

Pros
  • Durable carbide tip for longer lifespan.
Cons
  • Prone to chipping during heavy use.

Crashed on first contact.

Broke on first use. Understand, I drilled D2 hardened steel, but I use a milling cutter and cutting oil at 1500 rpm. Also, I broke a solid carbide drill bit trying to drill a hole. Hardened D2 steel is very strong. I'll try Artu-Drills and see if I can do it.

Pros
  • Power tool parts and accessories
Cons
  • Discontinued
