Review on ZJchao Tungsten Carbide Drilling Engraving by Duane Rogers

Revainrating 5 out of 5

The shank is not 1/8 inch! 2.973mm

Wrong description of shank size; it is not 1/8 inch. They are 2.973mm tall. Slipped right out of my DW660 after a hit. Returned, cannot be used. Despite the incorrect shank size labeling, they actually looked like pretty good bits, a Dremel 3mm collet should hold them well.

Pros
  • Comfortable to use
Cons
  • No instructions
