Product Selection Differences for Printed Circuit Board (PCB) Drill Bits
When selecting Printed Circuit Board (PCB) drill bits, there are several key differences to consider:
Material: PCB drill bits are typically made from solid carbide or high-speed steel (HSS). Solid carbide bits are more expensive but offer better precision and longer tool life compared to HSS bits.
Coating: Some PCB drill bits come with coatings such as TiN (Titanium Nitride) or TiCN (Titanium CarboNitride) to improve wear resistance and extend tool life.
Size: Drill bits are available in various sizes ranging from small diameters for fine traces and holes to larger diameters for larger components or holes.
Flute Geometry: Flute geometry affects chip evacuation and drilling performance. Different flute geometries are optimized for specific materials and drilling conditions.
Point Angle: The point angle of the drill bit determines the type of material it is best suited for. Common point angles for PCB drill bits include 90 degrees and 118 degrees.
Shank Type: PCB drill bits come with different shank types such as straight shank or reduced shank. The shank type determines how the drill bit is secured in the drill chuck.
Quality and Brand: Consider reputable brands known for producing high-quality drill bits to ensure consistent performance and reliability.
Price: While cost is an important factor, it’s essential to balance it with the quality and performance of the drill bits to avoid frequent replacements and potential damage to the PCB.
By carefully considering these factors, you can select the right PCB drill bits that meet your requirements for precision, durability, and performance.
