What are PCD tools?

PCD tools or known as Polycrystalline Diamond (PCD) apply in the process of cutting materials such as aluminium, brass and copper, graphite and non-metal materials.

So, if you want to obtain high abrasive resistance and high hardness, PCD cutting tools is the name.

PCD tools primarily result in a longer lifespan for the cutter and they customize designs to fit your exact measurement specifications at their best.

Uses of PCD tools in the Automotive industry

PCD tools perform outstanding surface finishes and excellent productivity.

To meet perfection in the manufacturing of auto parts, PCD cutting tools come in various grades for specified purposes.

Grain size



For applications that require mirror finishes on aluminium alloys, titanium and composites due to its extreme edge sharpness or retention.


For complex tools that require excessive processing.


Ideal to perform roughing and finishing with a single tool. And, perfect for low to medium content aluminium alloys.


Provides optimum wear resistance for abrasive machining conditions. Hence, ideal for milling and rough cutting of aluminium alloys.


Gives excellent wear resistance, edge strength and quality, abrasion resistance and good thermal stability. So, ideal application areas include MMC, high silicon aluminium alloys, high strength cast irons and bi-metal applications.

What are the automotive cutting tools?

The automotive industry revolves around PCD drills and reamers. And, these cutting tools manufacture the best auto parts making the automotive industry capital of the world.

So, here are the PCD tools and their application in the automotive industry.

PCD Reamer

You should use PCD Reamers for precision machining of aluminium and other non-ferrous metals to achieve the parts requirement finish and accuracy. Also, reamers are end-type tools that cut by the chamfered edge at the outside diameter of a preformed hole.

So, the lead angle provides very effective cutting action during high-speed machining.

PCD Step Reamers, on the other hand, complement this perfecting action further as they perform cutting with greater accuracy. Hence, making the automotive industry famous for PCD Step Reamers.

Not to forget, other PCD reamers include regular reamers and piloted ones.

PCD Drill

Besides reamers, there is a wide range of PCD drills and step drills in use in the automotive industry. They rough the hole’s processing and finish cuts.

Also, the various pointed geometries cover all possible applications in the automotive industry – from drilling the pre-cast and blind holes.

Depending on the hole depth, the wall thickness and interrupted or non-interrupted cuts are the reason for different types of drill bits.

The typical PCD drills in the automotive industry are:

Center drill Consists of a pilot drill and a countersink that is used to create holes at the centre of a piece.
Piloted core drill To use in a valve guide and seat machine that comes in various shank sizes.
Core drill Opens holes 20% to 40% under their major diameter intending for straightening and truing holes.
Step drill Drills metal up tot 1/4 of an inch thick to enlarge a hole as the bit drills through the metal sheet.

What are the automotive parts that require PCD tools?

PCD cutting tools are demanding across the automotive production process beginning from the alloy wheels, cylinder blocks, cam and crankshaft casing machining to milling, boring and reaming gearbox housings.

Besides, PCD tools perfect the finishing of a brake disc, wheel hub and pistons.
