Perfect Point Launches Carbonite Carbide Tool

Reading time ( words)

Perfect Point and Jinzhou Precision Carbide have released the new patented Carbonite carbide Tool. Carbonite is an enhanced hybrid single-flute geometry with a proprietary coating. It is designed for ultra-high technology, extremely high-aspect-ratio builds, and HSLL substrates. 

Carbonite offers excellent accuracy due to a significantly thicker web design. The single-flute geometry offers a much greater flute volume allowing for better debris evacuation as compared to traditional two-flute designs. 

In addition to these design attributes, Carbonite has a proprietary coating allowing for improved wear resistance and better debris evacuation. The lubricious finish of the tool results in a cooler drilling process. This coating is only a fraction of the cost of Diamond-like coatings and results in cleaner holes and dramatically improved HWQ.

Shane Stewart, VP of Perfect Point, said, “We are delighted to introduce our new Carbonite  tools to North America. This revolutionary design will allow PCB manufacturers to eliminate the need for premium backup and entry materials. Our Carbonite tools perform better than Diamond-coated tools at a much lower cost.”


Standard two-flute designs have more flute volume near the point, and less near the shoulder.  This flute volume mismatch causes debris pressure within the flutes and creates greater frictional contact against the hole wall.  This frictional contact generates heat and causes wear. Hybrid single-flute tools have an equal flute volume at tip and shoulder for a more consistent debris evacuation, minimalizing heat and wear during the drilling process.

The thicker web of the tool provides excellent rigidity, therefore this tool is offered in extended flute lengths allowing for aspect ratios exceeding 30:1. 

As can be seen below, Carbonite is a much stronger and rigid tool design that will drill much straighter and is far less prone to deflection.


Carbonite's proprietary coating has a hardness rating of Hv3500~7000 and friction coefficient of ≤0.1. The coating provides a significant reduction in carbide surface abrasion, which helps maintain sharp cutting surfaces for prolonged tool life. The cost of the coating is only a fraction of the cost of ownership for diamond-like coatings.

EIPC’s Winter Conference in Lyon, France: Day 2 Review

02/20/2018 | Pete Starkey, I-Connect007
The first day of the conference had started and ended in the dark—a long and technically intense day! After a convivial conference dinner and a good night’s sleep we were back on the bus, this time in daylight at the slightly later time of 8:00 a.m., for the journey from downtown Lyon back to Alstom’s conference facility in Villeurbanne, and it wasn’t raining. In fact, there was even some sunshine later in the day!
