The mistake that a lot of people make is using high speed steel twist drills at high speeds. If you search for "machining speeds and feeds" you will find a lot of information about the correct speeds to run cutting tools against different types of metal. Twist drills are the category of cutting tool you are looking for.

As soon as the heat starts to build up on the tip, the drill bit can lose the hardness that make it a cutting tool. Using HSS drills at low rpm with cooling fluid or lubricant can provide a large quantity of successful holes in metal. TThere have chunks of carbide on the end, and carbide will make easy work of even the hardest steel, and allow you to use high rpms. (In the process of opening holes to continue to add water for cooling.)

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 straight round shank of our bits means you can use this drill bit with nearly all types of machines.
