0.3-1.6 mm Micro Mini Drill Bit Set Tiny Drill Bits Small Shank Full-Ground HSS Twist Drill High Speed Steel Boards Tiny Drill Bits for Dill (40 Pieces)

Drill bits work great but, I wish that I hadn't bought so many bits since I only needed one small size. Most of the drill bits that come in this case are extremely tiny and would probably break easily. I don't think that I will ever be using tiny drill bits like these in the future.

Unic drill bits for fine special jobs

A lot of the bits fell out of the container and or were jammed so bad I had to break plastic to remove. Bits are fine

I wanted some drill bits to be used for drilling pilot holes for wood screws,etc....the biggest bit in this set is good for that but the rest are too tiny in diameter for THAT, but for small hobby rotary tool enthusiasts these would be perfect and highly recommend. These bits are ABSOLUTELY TINY in diameter and the fact that they can even make bits this small and order them from Amazon is amazing. The smaller ones are the size of a sewing needle and maybe even smaller than that.

This product description is untrue. I measured all the drill bits with a digital caliper. The set does not contain a set from 0.3 to 1.6 mm (in 0.05 mm steps). The actual contents are (quantity x size in mm) 4 x 0.48, 4 x 0.58, 2 x 0.68, 2 x 0.78, 2 x 0.87, 1 x 0.98, 1 x 1.16, 1 x 1.30, 1 x 1.37, 1 x 1.48, 1 x 1.58. This is true for all 3 sets I received. The points on the ends are flat and they drills are not sharp, even to cut soft materials like styrene. They are effectively useless, poorest of quality and untruthfully described. Don't waste your money.

I bought these bits for model ship building. They worked okay for drilling wood and plastic parts, but ends are poorly ground and are incapable of drilling metal castings. Many of the bits are not pointed at all. Not worth even the small price I paid for them.

Hopes were achieved. Actually lasted six uses! Fender/SQUIRE Telecaster thru-body stringing was changed to thru-bridge, with these!

These are great little bits but be warned. They are tiny and easy to snap!
