PCD Drills & Micro Drills

PCD Drills for Ceramics, Tungsten Carbide & SiC

Sundi develops application-specific PCD drills for zirconia and technical ceramics, tungsten carbide, silicon carbide and graphite. For multilayer PCB and composite laminates, micro PCD drills are developed around the material stack and hole requirement.

Hard-Material Drilling Solutions

The main applications are hard, abrasive materials and multilayer micro-hole drilling.

Ceramics and SiC wear carbide rapidlyPCD cutting edges are used for zirconia, technical ceramics and silicon carbide when conventional carbide loses edge life too quickly.
Tungsten carbide needs PCDPCD grade and cutting conditions are set from the carbide grade, hole diameter, depth and coolant.
Multilayer PCB drives micro-drill wearMicro PCD drills are developed for copper, resin and glass-fiber layer stacks where higher layer counts increase wear and hole-consistency demands.

We use the latest new material CHEVRON to braze on the top of the carbide body, then machine the tool body and the PCD area at one time by the electrical discharging process, which makes the tools have a good consistency. These drills are widely used in the new composite material, such as aluminum alloy, Sic, carbon fiber, PMMA, plastic, and so on

body allows to increase tool life over carbide, meanwhile, the internal spiral coolant can provide many benefits that save both times and offer better tooling life, By reducing the temperature of both the drill and the drilling service and increasing lubricity, the tool is subject to decrease wear and tear.

The top of the PCD solid nib is formed with special PCD material, it is developed specifically for the drilling of composites and composite/Stack/AL/Ti applications, Because of its solid nib top, the PCD solid nib has strong resistance to cracking and chipping and the stability of the tool is significantly improved.

We tipped PCD on the top and chamfer of the drills, this kind of PCD step drill can locate directly the position of the holes and drill the 45° or 60° chamfers correctly, it helps workers to reduce working difficulties and workload. According to clients different requirement for the material or holes, we can add double outlets to lower the impacts from chips when machining.

Straight flute PCD step drills, often referred to as PCD reamers (drill reamers), are designed for high precision machining of brittle and powder-forming materials such as aluminum alloys, ceramics, graphite, and composites. They ensure stable cutting, smooth hole walls, and excellent dimensional accuracy. With long tool life and consistent performance, they are ideal for fine hole-making and finishing applications.

PCD Micro Drill

The micro twist drill is a specific type of solid carbide drill. It has a drill tip diameter ranging from 1mm to 2mm, and its tooling life is obviously longer than that of traditional carbide drills.

frequently asked questions for PCD drills and catalogs

FAQ

Most frequent questions and answers
How do I choose between a PCD drill and a CVD diamond-coated drill?

If you care more about tool life and a very smooth hole surface, PCD is the better choice. If you need something more affordable and tougher against impact, then the CVD-coated drill makes sense.

Do you have PCD drills in stock?

Normally no. These drills are made for specific jobs, so they’re produced after you order. Most of the time it takes around one to two weeks.

Can PCD drills be re-sharpened?

Yes, they can. But it has to be done on special machines, and only a few times before the tool wears out.

What cooling options are available for PCD drills?

They can be built with outside coolant or with coolant through the tool. The right choice depends on how deep the hole is and what machine you’re using.

How long does a PCD drill last?

Much longer than a carbide drill—often ten to fifty times. But it’s not fixed; the life depends on the workpiece material, cutting speed, and cooling.
