About this item

  • Ultimate Drill Bits Set - 5 titanium plated step drills in sizes 3/16-1/2'', 1/8-1/2'', 1/4-3/4'', 3/16-7/8'', 1/4-1-3/8''. Effectively replaces 50 conventional drill bits. Countersink bit sets are available in sizes 1/4'', 3/8'', 1/2'', 5/8'', 3/4''.1 automatic center punch.
  • High quality drill set - both sinker and step drills are made of high speed steel, it can extend the service life even in extreme temperature. Titanium-plated step drills greatly improve durability and sharpness, reduce friction and cooling operations, and perform well in heat, corrosion and rust resistance.
  • Excellent design - stepped bit, 118° split bit, double groove design, increase cutting speed by self-centering, prevent walking, faster chip removal and easy particle discharge. Countersink bit sets are ideally suited for countersinking 90° holes in wood and soft metal countersunk screws and fasteners.
  • Precise positioning - Using automatic center punch positioning allows you to find exactly where the hole needs to be drilled every time.
  • Excellent design - all tools are placed in an aluminum box and they are tightly wrapped with foam. So you can give it as a gift to your father or a loved one.

These work excellent in, well, nothing that I could find. Definitely not for steel. The large one took everything it had to go through one layer of body panel. That is seriously bad. Don't waste your money like I did.

The case is pretty nice to keep things organized. Center punch is nice and effective. Counter sinks look and work nice. The cutting surfaces are clean and sharp with good angles.The stepped drills though are not as clean on the tips. The largest one has the cleanest tip with a clean and clear chisel while the rest of them are not as clean and two of them seam to be offset a bit going into the flutes. My recomendation is not to use these to start holes just by themselves, as their primary purpose is to expand existing holes.Overall I think this is a nice kit for the price as it is versatile and will do what it is needed if used correctly.

They seem fine for wood. Maybe aluminum. However, they burn out immediately with use on even 20 gauge mild steel.

Didn't have to spend $87 for a 1 inch countersink. With the bonus of a box of bits. Worked well for my application. Plank on my drill press table.

Step bits are decent, prick punch is garbage. Cheaper quality for sure.
