pcb drill bits - pcb drilling material



What is PCB drill bit?

 
They're made from carbide (tungsten steel). and are suitable for circuit boards, electronics, SMT, molding, metal processing, telecommunications. and other uses.  Each drill tip has a high hardness, wear resistance and strength. and they're also super sharp which helps when drilling through PCBs.  The drill bits also don't bend or break and come in a nice plastic case to store your tips when you're not using them.
 
The PCB drill bits used in CNC machines. for drilling printed circuit boards for electronics. but their toughness and accuracy lend them to uses in other industries. Our carbide drill bits are also used in medical. and aerospace manufacturing for drilling small precision holes. Carbide PCB drills are well suited for drilling composite materials. such as G10 epoxy laminates, phenolic, plastics as well as various metals. They are also used for drilling ceramic castings.

printed circuit board drill bits features

 
Drill has a large scraps discharge space, little resistance. and during the scraps discharge. The cutting edges avoid partial hole, ensure the quality.
 
Shank diameter: approx. 1/8″ (3.175mm). Use high-quality materials and fine grinding process. makes a bit more sharp cutting edge, reduce cutting force and broken drill. improve the quality of hole wall. Long life, it can drill 2000-5000 pcs under normal working conditions. also can return grinding 4-5 times.
 
No wobbles and sharp enough to do the job, nice color coded. have the sizes printed on the shafts, come in a handy storage case. The shafts are all the same size, does not need to use a needle-chuck. It makes these bits easier to use.
 
The smallest one is so small it is hard to see with a magnifying glass. others are perfect for cleaning out small orifices. These are carbide and so you can shatter them if you don’t know how to respect carbide. Power hand drill is no steady enough to use these types of drills, use a drill press instead. And you need to be careful to not put much pressure on the bits when using them. and careful that the only force you apply is along the bit and not to the side.
 
You can use it to engrave on glass, wood, metal, about anything.
 

pcb drill bits advantages

 
The pcb drill bits 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 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 run at roughly 6,000 to as much as 20,000 RPM or more.
 
cautions:The cutting edges 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.
 
These are excellent. They are sharp and strong. I use them for drilling FR2 and FR4 copper clad PCBs. and these bits make clean holes without any burr to clean off on the entry or exit side of the hole. I pushed the 0.9mm bit through an FR2 PCB using my drill press when the motor was off. and it made a clean hole through the board without breaking.
 
Sharp micro drills, work fine in a Dremel tool and drill-press. Short enough to make it easy to do a straight hole but long enough for doing what you need to. Perfect for small carving.
