Description of πŸ”§ MIBRO 492470 Cobalt Artisan Creations

Tougher- Made with a special Cobalt alloy of M35 steel, they can be used on hard or abrasive materials like stainless steel and space age alloys. Stronger- Extra thick drill core adds rigidity and strength. Makes life easier with a 135 degree split tip to eliminate "skating". Three flats on bits 3/16-Inch and larger give the drill chuck a stronger grip on the bit, especially useful in harder materials. Because of the Cobalt bit's longevity, they are an excellent value.

Powerful and Durable Bits

I needed durable cobalt bits that can handle heavy-duty drilling tasks. As a result of my tests, I determined that these bits from MIBRO are simply amazing. They cut through steel and other tough materials smoothly without easily wearing out. The bits come packaged in a handy storage case, which is perfect for keeping things organized. However, they are a bit more expensive than other options in the market.

Pros
  • Powerful and long-lasting
Cons
  • Pricey compared to other options

Excellent product, cuts through 1/4 " thick steel like butter.

These drill bits were a great buy Needed something to drill through an old digger shovel to install the headlights The digger was clearly heavy and solid No problem cutting through the steel to install the headlights Also a good bit case very sturdy and a good size Can't say something bad about this product, very good.

Pros
  • More durable - made from special M35 cobalt alloy steel, can be used on hard or abrasive materials such as stainless steel and aerospace alloys.
Cons
  • Crumples easily

Cuts through everything so far

They're strong and I've had no problem breaking, but I can feel it in them. I haven't pushed them and have so far gone through any steel, even a trailer frame, with little effort. Be sure to go from a small pilot hole (and use oil) to larger pilot holes, hold tight too because they can generate a lot of torque. I would buy again.

Pros
  • Stronger - Extra thick core adds stiffness and strength
Cons
  • Damaged
