Chrome Vanadium Spring Steel shaft that is through-hardened for Superior Durability. Shot-peened, double tempered finish reduces breakage. Copper braze material gives high heat resistance and reduced tip loss. Universal SDS-Max Shank fit.
This industrial drill bit was a complete waste of money. It didn't drill through even standard industrial materials and broke on the first use .The product claimed to be heavy duty but it couldn`t even handle basic tasks. The only pro was that it came in nice packaging. But overall, I would not recommend this drill bit to any industrial and scientific users..
Pros
Durable and long-lasting
Cons
Heavier than some other SDS Max drills on the market, making it more difficult to use for extended periods of time
This industrial and scientific drilling tool is a game changer for heavy duty jobs. The SDS Max design offers efficient and consistent drilling while THE robust build ensures longevity and durability .The power of this tool is impressive, making quick work of even the toughest materials. The only downside is the weight which can be cumbersome during extended use. Overall, a top choice for professionals in need of a reliable and powerful industrial drill bit..
Pros
Durable and long-lasting
Cons
Not suitable for small or delicate tasks due to its size and power
Drilled about 40 holes in relatively fresh concrete, averaging about 15 inches deep - chisel still looks new. Cuts like butter in concrete - 4 flute head gets the job done very quickly. Use with Bosch 11240 (which is great too).
