I'm assembling metal parts for my 3D printer and needed to drill out the mounting holes for the motor mount. This 23/64" drill bit is ideal for 5mm SHCS (or low head SHCS) and the shoulder cut with the smaller diameter tip leaves enough material for a 5.5mm drill bit. These drills also cut very well.
Pros
No-spin shank eliminates the hassle of spinning the bit in the chuck
