10pcs 0.15-3.05mm Carbied PCB Mini Drill Bit
Shank diameter: approx. 1/8″ (3.175mm)
The cutting edges strictly avoid partial hole, ensure the quality. Sharp and twisted flute will make the drilling be more easy and effortless. Suitable for wood, aluminum, plastic, etc.
The variety of sizes is nice and the collar makes fitting them into the chuck easy. Excellent product at great value. These are exactly what they say on the tin. For circuit boards or even presumably for really fine jewelry work, they are a good tool and quite affordable.
These are for use in CNC or special drill press, or at least high quality one, with low vibration level. Depending on the size, these bits must be run at roughly 6,000 to as much as 20,000 RPM or more.
