About this item

  • Black gold high speed steel is the long lasting material when it comes to common drill bit materials, not only will the bit's structural integrity withstand tremendous heat and wear, but more importantly black gold bits can drill through tougher materials than common HSS bits.
  • With a 135 degree split-point, these drill bits will catch on the work-surface with greater ease and not wander all over the surface making scratch-marks. This means that after securing the bit in the machine all that is needed is a steady hand to point and apply pressure, and that's it.
  • The 3-Flat shank of our bits means you can use this drill bit with nearly all types of machines.
  • The jobber length is the most commonly used length to diameter standard of drill bit in the US, the length is scaled according to the diameter of the drill head to give maximum force with maximum support so as to keep the bit from bending under the pressure, all the while keeping the machine a comfortable distance from the surface so as not to come in contact and scratch it.
  • Included in the package is 6 pieces. Making for a total of 6 drill bits in total. This dimension in a plastic pocket (pvc pocket), this style of packaging keeps waste low and remains the simplest way to keep this many bits clean, out of the dryness or wetness of the air.

I have tried a lot of different drill bits. A lot of them are garbage and won’t cut steel. These are good quality and do a nice job.

Not the best bits I have bought, but they are pretty good for the price.

Only issue is the bit dances around sheet metel before grabbing hold once it does its cuts like butter

I have multiple drill bit sets, and they are all missing this sized bit. I use this size a lot, and either wear them out or break them.Rather than replace the entire set, this is an easy way to make all the kits usable again.These bits are sharp, well made, and cut wood, plastics, and soft metals, easily and cleanly.

I used this bit on my loader bucket and drilled through at least 3/8 inch steel without difficulty. Slow speed, lots of pressure and no cutting oil used.
