CoroCut® QI

Optimized for internal grooving and face grooving on small diameters

How to choose a face grooving tool

A- or B curve

  • A-curve = For internal machining
  • B-curve = For face grooving to boss

Insert width (CW)

Use the widest insert and tool that can be used for your groove. A wider holder has greater stiffness and gives more stability.

Maximum cutting depth (CDX)

Always use a tool with the shortest possible cutting depth (CDX) to obtain maximum stability.

Diameter range of the first cut (DAXIN and DAXX)

Use the tool for the largest diameter that fits your groove. A tool for a larger diameter is less curved and hence more stiff and stable. It also offers improved chip control.

Machine interface: QS™ shank, CoroTurn® SL head or boring bar

  • QS™ shanks: only with B-curve
  • CoroTurn® SL heads: both A- and B-curve
  • Boring bar: only with A curve

0° or 90° holder?

  • QS™ shanks: 0° or 90°
  • CoroTurn® SL heads: 0°
  • Boring bar: 0°

Application tips

Internal grooving methods

Internal grooving methods

Depending on the application, there are a few different strategies to consider for internal grooving.
Learn more about how to apply roughing with a non-linear tool path, roughing with radial feed, roughing with side turning and finishing, among other important considerations.

Face grooving methods

Face grooving methods

Depending on application, there are a few different strategies to consider when face grooving.
Learn more about how to apply roughing with axial feed, roughing with side turning and finishing, among other important considerations.

Overhang

Overhang

To avoid vibration, the setup should have the shortest overhang with the lightest cutting geometry.

EasyFix™

Always use CoroCut® QI bars with EasyFix™ collets. A spring plunger mounted in the sleeve clicks into a groove in the bar to guarantee the correct center height for each tool setup. The metal seal offers good performance for coolant pressure up to 150 bar.
