These are the FASTEST drill bits I’ve ever seen! Absolutely incredible! These are mechanic length drills with 135 degree split point tips to avoid walking, followed by a short series of steps up to the full drill diameter. This allows drilling full length holes into mild steel and other metals with the speed of a step bit.

If you've ever seen the fancy new Matco Drill Bit set with the stepped tips, these appear to be identical, as far as I can tell.

This is NOT a sponsored video. I purchased these myself and love them.
