They are the best unibits optimized for cordless drills made in the USA. They are dual-flute and have laser-engraved reference marks. Excellent craftsmanship and not a flaw in the design.

If you make an occasional modification of some boxes or other products made of soft sheet metal, they are more than enough.ġ/2″ bit is long and has small steps, so it can peel material in thin layers. And I don’t recommend starting a new hole with these bits, except maybe in a very soft material. Neikos are not the best unibit for stainless and hardened steel (better use cobalt bit), but for plastic, wood and thin metal sheets they are perfect. Two-flute design clears chips faster, three-flatted shank fits into power tools chuck more securely and eliminates slip. Titanium coating helps to reduce overheating of the cutting edge. These Neiko bits are made of HSS with Titanium coating, and have 135° split point tip. They are the best unibits for drilling holes in plastic, aluminum, copper, stainless steel and many other types of sheet metal.
