Works Well - Electric Drill Parts & Accessories

The drill drills well in steel and wood. However, I have not seen such a profile for a drill (see attached picture). In other words, once it becomes dull, it's impossible to restore the burrs on the cut surface. The bit should still work after a good sharpening, but maybe not as well as when it was new.

Pros
  • High quality M42 8% cobalt steel, 68-70 HRC (Rockwell Hardness Scale), typically offers the best resistance to heat, wear and chipping as well as long tool life.
Cons
  • Instruction No.

HIGH QUALITY TUBE THAT WORKS WELL ON IMPOSSIBLE STAINLESS STEEL

I had some stainless steel that conventional drill bits were useless with. After some research and reading reviews I got them. They work where other drills don't. I drilled 8 holes with one of these drills while trying so many other drills. As soon as they arrived, they started to work. Be careful with anything Cobalt Driller says. It's about as good as you can get. Be sure to use oil with them and also use water to cool them down while drilling. One of the best drills I've ever had.

Pros
  • For cutting stainless steel, carbides, aluminium, plastics and hardwoods.
Cons
  • Something else

2-pack M42 8% COBALT Steel 9.5mm/3/8 " Stepped Tip

Drilling stainless steel (SS) or tough cast iron requires a quality drill bit. Using a good quality drill bit makes my DeWalt Drill power tool much more efficient. These are high quality M42 8% Co HSS drill bits (2 equal sizes) and are supplied in a plastic carrying case. (Figure 3). If I want to drill stainless steel (SS) this is the bit I want to have and use. These quality tips make it much easier for me to implement DIY projects. They are sharp and when used with a quality cutting oil likeโ€ฆ

Pros
  • This cobalt drill can typically work three to five times faster. Despite the higher price, the cost per hole is lowest when using the cobalt drill as it can create many more holes.
Cons
  • Expensive
