DSPIAE Tungsten Steel Drill Bit 0.3~3.0mm for Hand Drill

Great drill bits but delicate buy extra

This is the second time I’ve bought these drill bits. They are fabulous to work with however they are delicate. I broke a couple of .3 and .4mm bits, so I needed more. This is in no way Dspiae’s fault I dropped the bits they broke. I strongly recommend you buy 2 sets of bits or at least extra .3 and .4mm bits.

Awesome

Nice bits

With my limited use, the bits are performing well. Time will tell about durability.
