adjustable deep hole counter boring head with big stock removal diameter 150-500mm big stock removal

The push boring head has single indexable insert which can be used for

counter  boring . precision of hole diameter IT9-10.Surface roughness:Ra6.3 outside or inner side thread  is aviliable.

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.

Our  range type Counter Boring Reaming tools can be designed offered as range tools. These tools are designed with deeper pockets which are furnished with adjustable shoes. When an alternate tool diameter is needed, all one has to do is shim the tool out to the new diameter required. In larger diameter tool sizes, it is possible adjust the tool size up to as much as 10mm  on diameter.

We offers specialty multi-cutter pull boring tools for centrifugally cast tubing. These tools are designed to follow the camber of the cast tube while maintaining uniform wall thickness and   they are capable of obtaining feed rates up to 100-200mm/min.

Consider these unique advantages BTA   Indexable Counter Boring / reaming Tools.

· Bore depths greater than 100 times the tool diameter.

· If conditions are ideal, hole drift as little as 0.02mm per foot can be obtained.

· Stock removal up to 16mm per side depending on tool size.

· Tools available in either push or pull boring versions, in either I.D. or O.D. chip removal.

· BTA single cutter pull type boring tools for critical straightness requirements.

· Carbide inserts with factory ground circle lands (available coated or uncoated) that insure better hole finish and closer I.D. tolerances.

· Preground carbide guide pads are reversible for double the life.

· Fiber or nylon pads reduce vibrations for better bore finishes and longer insert life.

· Only 4 different inserts are required to cover the complete range from 38mm  and up to 500mm.
