Drilling a firing pin hole...amazing speed!
This video showcases the impressive speed and effectiveness of a super-expensive tungsten carbide, through-coolant drill bit being used to create firing pin holes in BFG-50 bolt heads. The description highlights the difficulty of drilling high-strength alloy steel and uses a humorous analogy of being accused of witchcraft if this technology were shown centuries ago. The drill's performance is presented as almost unbelievable due to its speed and capability on tough materials.
