Professional Precision 0.3mm - 3.0mm PCB Tungsten Carbide Micro Drill Bits Twist Drill Bits CNC Milling Tools

Drilling for PCB Wood Metal Plastic PVC Amber Jade

High-quality materials, exquisite craftsmanship, safe, reliable and durable, long service life, complete specifications, convenient and flexible use, and better cost performance. 

PCB drill bits made of carbide (tungsten), with high hardness, high wear resistance, high strength, anti-bending,anti-breakage, etc. 

Tungsten Carbide drills with a 1/8 inch (0.125 inch / 3.175 mm) shank.

Tungsten Carbide drills bits stay sharper for longer than high speed steel (HSS) and cobalt bits HOWEVER small diameter bits such as these are brittle. They need to be used with care and attention as they break very easily.

Best used at high speed in a Drill Pillar / Press.

It is suitable for circuit board, electronics, SMT, mold, watch repair, metal processing, telecommunications and other industries, and can be used for drilling iron, glass fiber, etc. Processing range: PCB, SMT, CNC, mould, engraving, plastic, copper, stainless steel and other hardware processing.

Product features:
①Large chip removal space of the drill: small chip removal resistance, smooth chip removal, small heat generation from drilling, and reduction of drilling dirt;
② Extraordinary cutting edge sharpness: due to the use of nanotechnology and advanced grinding process, the cutting edge of the drill is sharper than before, which can reduce the cutting force, lower the rate of drill breakage and improve the quality of hole wall;
③ Tool design based on customer application: the drills are available in a wide range of varieties to meet different application requirements. All parameters of the drills, such as core thickness, core taper, etc., have been carefully designed with obvious effectiveness;
④ Strict symmetry of cutting edges: favourable to efficient cutting and avoiding drilling offset.

The limit ring on the body of the drill bit varies in colour from batch to batch, red, purple, blue and yellow are all possible. The colours are shipped randomly.

Caution:
-  It is a special accessory for precision equipment such as engraving machines and high-speed drilling machines. Hand-held drills and electric grinders are unstable and easy to break when drilling holes!
- The drills are very sharp, so be careful with them and don't cut your hands.
-  Must not be clamped on the hand drill high-speed rotation to punch holes, so that the amber will certainly collapse.
-  When drilling, you should pay attention to the amber powder while rotating and clean up the amber powder at any time.
-  Pay attention to the concentricity of rotation, especially in the barrel bead drilling, because the drilling distance is long, drilling deviation from the concentricity is too large, it is easy to cause the broken needle.
-  Grab the end of the drill bit with your hand and slowly rotate the hole, when you are about to punch through, especially reduce the speed and force. If you feel the needle tighten while rotating, please back out the needle immediately and clean the hole powder to re-enter.
