Our Counter Boring tools should not be confused with shallow- hole, Counter / Finish Boring Reaming multi-cutter counter boring tools or single point boring bars that are used on machining centers or CNC lathes. Our  Boring Reaming tools are generally for bore depths deeper than 7+ times dia. (L/D) and are used to open up existing holes with increased precision, productivity and versatility. In the majority of cases, one will be able to produce holes with closer tolerances and finer surface finishes, possibly eliminated the need for honing.

We offers a full line of single indexable insert tipped tools ranging from38 –1000mm  diameter. When required, multi-cutter or stepped Counter / Finish Boring Reaming tools can be furnished to conform with component design criteria or as roughing tools for subsequent form boring operations.

The Counter /Finish Boring  tools are also available in both push and pull styles. Pull style tools are the first choice for accurately opening up and straighten an existing hole. Additionally our counter boring reaming tools are self piloting but when concentricity is of the utmost importance. These tools can also be furnished to pilot off of the existing bore.
