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.

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.

Seem to be made of high grade steel as they can bend slightly while drilling without snapping unlike so many other small bits. Have used only the larger sizes so far as you would need a micro chuck to be able to use the smaller sizes. Only disadvantage is the case they come in. Unclear how to open it and when you manage to get the cover off - they all spill out as it is a one-size-fits all holder. Open it over a towel so you don't have bits rolling away all over the place.

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.

Love product! Great value! Fast shipping! Just as described! Well pleased! Will buy from them again!

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.

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

one of the three sets was missing the 1st bit from the case, same problem as others have mentioned. decent case.
