PCB Drill Bits

The PCB drill bits that we sell are made of high quality micro grain carbide. They are used primarily 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 widely used for drilling ceramic castings.

 

With over 10 years of experience using and selling PCB drills, Jinrui Precision Carbide Technology can help with reduce your set-up time and shorten your learning curve. We can suggest feeds and speeds parameters based on the materials, board lay-up and equipment capabilities. We can also provide the support tools such as entry, backup material and soft tooling materials.

 

We carry an extensive line of drills with extra-long flutes used for drilling probe plates or In-Circuit test (ICT) and functional test fixtures or for any project where you need a longer reach tool.

 

At Jinrui Precision Carbide Technology we are also able to produce custom diameters and flute lengths to customer specs.  We can often turn small lot specials within 2 weeks.
