Genmitsu 30pcs PCB Drill Bits Set, 0.1mm-3.0mm, 1/8" Shank Spiral Flute CNC Router Bits for Print Circuit Board Jewelry CNC Engraving, PD30A

A very good set of drill bits with a wide range of sizes. Ideal for modelling. Small sizes need care when handling but produce fine holes. Need a cordless drill to use with slow speeds

Great little drill bits.

Could do with markings as to drill size, you have to measure each one to find the one you want.

Great set of drillls. Purchased for scale modeling. Shall definitely buy again.

Holding up well after making many pcb's. Difficult to identify sizes without a vernier.

Very useful, nice sizes in strong case

I love these bits. they cut through plastic fast. I mount them in my dspiae drill.

The bits themselves are very sharp and useful - albeit a little brittle. But there are no size labels on any of them, making drilling a matter of guesswork

Sehr präzise verarbeitet

Sadece baskı devre çıkartmak için ideal. Herşey için geçerli değildir.

Sharp. I would imagine the 0.1mm will have little or any practical use, unless your drill is zero run-out. The. 0.3mm works fine on mine through 0.5mm brass and 2mm styrene. As a result i am confident the 0.3mm bits and larger will be fine. I have used a few of the larger bits and they are sharp. Just go easy on the smaller bits. They will snap if you apply to much force.

Llegaron justo a tiempo para cumplir con un compromiso. Excelente calidad.

Très bon produit
