New machining techniques require new tools, which in turn lead to new machining methods. This constant interaction is the driving force which ultimately leads to progress. It is this very factor that leads to continuous development of tools and machine tools. Numerical Control of machine tools represent a milestones in production methods. However the increase in operating speed now possible, together with higher precision and production and automation, also places new demands on the tools.

Since the beginning of cutting technology for fine machining of bores, the reaming method has proved indispensable. One of the main reasons lies in the broad spectrum of application for which this process can be used - on all machines with either rotating or stationary tools.

Carbide Tipped blade reamers replaced the original HSS multi-blade reamers. Carbide tipped adjustable floating, pair of blades in a holder gave fine finish. Now single blade reamers with clamped, precision adjustable blade and guide pads have put a step forward.

The increasing use of NC-Controlled machines, particularly machining centers, have brought a further need for tools development which allow new methods of increasing performance to full advantage.

The cutting process is by means of a precision adjustable, rigidly clamped blade. At least two guide pads placed on the circumference of the head provide support and guide.

In Automatic production, it is vital that the chips removed do not affect the result. Copious coolant supply will also prevent chips affecting the results.
