Blade reamers are aimed for high precision bores, tight tolerances and fine geometric shape. They work with guides that support the machining forces and produces a good surface finish. The indexable blade is choosed accordingly the part material. Can be manufactured with carbide, coated carbide, PCD or CBN with specific lead angles and rake angles.

Hanna designs and manufactures multiedged solid tools as an alternative to reamers with replaceable blades. The choice between the two different concepts of tools must be analyzed and decided in each particular application, in order we can get the most efficient and economic process. In a very broad perspective, we can define the advantages of […]

Any type of reamer can receive a connection to be quick changed and keep a small run-out so that no setting adjustments are needed. This kind of connection is largely utilized in valve-guide / valve-seat reamers where the valve guide reamer must be changed frequently.

Hanna offers as part of it’s tool line, multi-edged solid reamers, as well as replaceable blade adjustable reamers. It is important to know how to select the type of reamers that is better suited to a specific job. In many applications the customer can decide for one or the other type, without compromising the performance. But there […]

The blade features are paramount for the reamer’s functionability and performance. Depending on the specific applications, the blades can be constructed from Carbide, Coated Carbide, Cermet, PCD and CBN. The cutting geometry also must be defined by the part material / chips characteristics. Important is that the available technology and know-how can be applied to […]
