Fine boring tools.

 

​The perfect

solutions are designed

specially for

every application.

PCD fine boring tools

Cylinder head

Today automotive components are made of Aluminium alloys due to its light weight & strength.

Preziss Diamant offers a complete

high performance PCD tool range

for high precision machining

of these components.

Cylinder heads, gearbox housing,

turbo chargers, brake pumps,

steering housing, valve body,

converter housing, steering knuckle and more components for which Preziss Diamant has developed, design and manufacture best boring and reaming solutions according

to customer requirements.

 

Product Quality

Tools are designed and manufactured

by the most qualified tooling engineers

and technicians, using the last advanced

drawing data-base and production

technology together with our internal

managing system that protects the design

and tool geometries content to ensure the

repeatability and reliability of each tool.

 

Increasing and optimizing productivity

Tools are designed to optimize the machining

process by increasing RPM's and feed rates

and reducing cycle time.

By combining tools together, we design & develop

multi-task tools conferring to the machining process

less down times and increasing productivity.
