GMT TOOLHOLDERS

A SYSTEM FOR THREADING
There is virtually no thread that cannot be produced with the GMT tooling system. This illustrates the wide range of toolholder/Insert combinations. (For example internal threads of 13 mm (½”)diameter bore can be produced with standard tooling).

RELIABLE AND ACCURATE CLAMPING OF THE INSERTS
An insert which is not securely clamped in the toolholder will soon become damaged, but even more serious, this can give rise to damaged work- pieces. The interaction between the retaining finger of the GMT clamp and the chamfer of the insert centre- hole, gives an extremely firm clamping action. The clamping mechanism is also easy to use.

INSERT SEATS DESIGNED FOR ACCURATE LOCATION
Accurate indexability and location are achieved by our modern production methods. This results in a tooling system which will have more accurate inserts indexability than comparable tooling.

ALWAYS THE SAME HEIGHT TO THE CUTTING EDGES
The height to the cutting is always constant in a GMT toolholder, even if the pitch angle is varied. This design feature eliminates the need for expensive special anvils and modification to the toolholders, which can also effect the height of the cutting edge.

A CUT ABOVE THE AVERAGE
Standard toolholders and inserts directly from stock are generally the best for economy. But it may sometimes be desirable to go a step further in an effort to achieve better economy, or where standard tooling cannot be used. We must then turn to special tools. In the case of tools for threading, GMT is a partner who can help to solve your problems and has the necessary resources to convert theory into practice.

INTERCHANGEABLE CARBIDE ANVILS GIVE THE TOOLHOLDER A WIDE APPLICATION RANGE
Various anvils are available for the majority toolholders. Pitch angels of -2 degreeup to +4 degree can be achieved by interchanging the anvils. A single toolholder can therefore be used for coarse and fine pitches, right-hand and left-hand threads.
