Reaming Tools Catalog - Komet

For maximum precision and concentricity
DIHART's DAH ® 50 HS compensating holders ensure that
the tool runs concentrically. They allow precision adjustment
of the tool in the µm range at the cutting edge reducing any
machine spindle error to a minimum.
Maximum concentricity guarantees reliable production for
extremely close tolerances.
BENEFITS for you:
DIHART DAH ® 50 Compensating Holder
High speed machining – with maximum quality
The quality of the bore, including surface finish, roundness,
parallelism and above all, dimensional accuracy are
improved considerably.
This significantly increases the process capability of DIHART ®
multiple blade reamers.

Proven hydraulic clamping
Maximum concentricity and repeatability
< 1 µ for uniform blade contact
Extremely simple run-out adjustment
Compact design
Optimum vibration damping for excellent surface
quality
Reducer sleeves increase clamping Ø range.
Speeds up to 25,000 rpm
Compatible with minimum quantity coolant (MQL)
4
Simple handling – reduced machine down times
In comparison to previous solutions the hydraulic chuck is
integrated into the new DIHART ® compensating holders.
This means one less connection.
Four adjustable screws allow rapid and precise adjustment
of the concentricity of the multiple blade reamer, reducing
run-out to virtually zero. The extremely slim design of these
new compensating holders ensures that they fit easily into
practically all tool magazines.
