Some parts have several bores in line with a blended angle in between. Insert holders with an adjustable insert cartridge allow the bore to be completed while producing the blend angle in one-pass, thus eliminating the need for follow-up tooling, such as an angled milling cutter.

The Twin Cutter’s ability to take on heavier cuts allows shops to be more efficient. Whether it's eliminating multiple passes on the same bore or possibly allowing the use of existing smaller tools to create a starting hole, our Twin Cutter boring heads get the job done. Sometimes cast parts have more material to remove than was initially expected. Being able to balance- or step-cut with the same boring head helps minimize tooling and cycle times.

Limitations of using milling tools to prepare holes for finishing become apparent as hole depth and volume increase. This is where BIG KAISER’s Series 319SW Twin Cutter boring head showcases its capabilities and can solve the issue along with virtually any other holemaking problem for the range of 0.787-8.000”.

Also offered for the Twin Cutter boring heads are accessory insert holders to perform auxiliary operations not normally associated with this type of tooling.

Any industry using castings or forgings can generally benefit from twin cutting. It is designed for heavy-duty rough boring and semi-finishing operations. The compact, sturdy design and positive geometry allow almost chatter-free operation even in interrupted cuts and high cutting speeds.
