About PCB Micro Drill Bit

Micro drill, also known as PCB micro drill bit, is a complex shaped micro holes drilling tools with spiral grooves.

In the PCB industry( printed circuit board industry, drill bits with a diameter≤ 3.175mm are referred to as micro drills. PCB micro drill is made of tungsten carbide as a solid, which belongs to the tungsten cobalt carbide group.It is made of tungsten carbide(WC) powder as the matrix, cobalt (Co) as the bonding agent, and sintered under pressure. There is also welding method. The handle material is usually made of 420 grade martensitic steel, while blade material is tungsten steel, and the handle and blade are bond together by welding.

PCB micro drill has high hole accuracy, strong chip removal ability, good rigidity, corrosion resistance, and wear resistance.

Parameters of Diamond Grinding Wheel For PCB Drill Bits

Selection of Abrasives&Bond for Diamond Grinding Wheel For PCB Drill Bits:

Diamond wheel is mainly used for PCB micro drill bit grinding, such as solid tungsten steel PCB micro drill bits. When processing welded drill bits which contains tungsten steel and stainless steel, diamond grinding wheel wears out both materials at the same time during the grinding process, resulting in faster wear of the grinding wheel. This increases the dressing frequency of grinding wheel, and increase the risk of deformation of stainless steel drill shank.

Our hybrid diamond &CBN grinding wheel can perfectly solve the problem. The feature of this kind of grinding wheel is that CBN abrasive part is used to process the stainless steel part of the PCB drill shank, and the diamond abrasive part is used to process the tungsten steel part of the PCB drill bit. It can maximize the performance of the grinding wheel and reduce the dressing frequency of grinding wheel.

There are metal bond, resin bond, and vitrified bond. Each has its own advantages.

Type of Binder	Self-Sharpening	Sharpness	Life	Dressing Difficulty	Price

Resin	5/5	4.5/5	3/5	1/5	2.5/5
Vitrified	5/5	5/5	4/5	1/5	4/5

Recommend Types Of Grinding Mode:

In terms of technology, the main production process of PCB micro drill bits include welding, rough grinding, fine grinding, fluting, cleaning, and etc. Fluting is an important step that requires extremely high equipment requirements.

Manufacturing PCB micro drill bits is the entire process that requires various types of grinding wheel, such as diamond cut off wheel for cutting bar material, cylindrical grinding wheel, centerless grinding wheel, peel grinding wheel, and diamond fluting wheel for slotting PCB micro drill.

Recommend Grit Size Of Diamond Grinding wheel for PCB drill bits:

When ordering diamond grinding wheel for PCB drill bit, please offer the parameters of the grinding wheel, the requirements for bond, the parameters of the processing object, and the brand of the machine tool.
