Compensation holder

For maximum precision and concentricity

Dihart®  DAH™ compensating holders

The Dihart®  DAH compensating holder ensures that the tool runs concentrically. They allow precision adjustment of the tool in the μm range at the cutter eliminating any machine spindle error. Maximum concentricity guarantees reliable production within extremely close tolerances. The quality of the bore, including surface quality, circularity, roundness and parallelism and above all the dimensional accuracy are improved considerably. This significantly increases the process reliability with DIHART® multiple blade reamers. The hydro-expansion chuck is already integrated into the DIHART®  DAH compensating holder. The extremely slim design of these new compensating holders ensures that they fit easily into practically all tool magazines.
