Cylinder Head Porting Tools 1

Cylinder head porting requires certain tools that without them the ends result can or will be compromised and so now we will discuss what professional tuners use to modify the cylinder heads.

The first tool that is used for porting by hand is a straight high speed die grinder, and these come in two types, electric and pneumatic type.

Electric type:

Pros......powerful, variable speed (not all) and unstallable

Cons.......heavy, bulky to manoeuvre in tight areas

Milwaukee 5192 4.5 Amp High-Speed Die Grinder


Pneumatic type:

Pros....... light thus less tiring and easy to manoeuvre

Cons......power depends on compressor size/volume and can stall easily

Ingersoll Rand 3108 Super-Duty 1/4-Inch Pneumatic Die Grinder



Of great use is a flexible coupler that can be used on both grinders but usually on the electric type so it will alleviate from the weight of the tool and be less tiring to do the job.

Now we delve into the cutting, grinding and polishing tools that we use.

Porters need to choose from different shapes and sizes of cutters for the required cut that is needed and also since there are two types of materials for cylinder heads that are Cast steel and cast aluminium that the appropriate cutter is used. Normally the best are Tungsten Carbide burr cutters and although they are more expensive they are very durable and make a better job.

The shapes that we usually use are the straight, round, rounded cone and rounded straight. The difference between the cutters from material to be used on is the amount of flutes they have and normally for aluminium the less flutes the better so it will not clog up and in my experience i tend not to use the same cutter on different materials as it will shorten the life of the tool.

Next time we will continue to talk on the tools we use for cylinder head porting as there are some interesting tools coming up........
