Review on Cobalt Jobber Length Hardened Stainless by Ben Boulanger
Too short for good results, less than 1.5 inches long
These 1/16" cobalt crowns are too short to be useful. I got really sick with the flu this month and missed the return deadline to get them back. They are NOT a standard length and are not long enough to wear to fit in a 29 bit drill set. When I chuck my drill bit, they don't have much length left to reach. They're just under 1.5" long and I kinda missed that because length doesn't describe it. I'm sorry, spend money on them.
Pros
- Pay attention to speed, pressure, and temperature control when drilling.
Cons
- Long Shipping
