CoroTap® 100
CoroTap 100 is a range of straight flute taps that are optimized for short chipping ISO K, ISO N and ISO H materials. For long chipping ISO P materials, the chip breaker design is appropriate. The taps are suitable for both through and blind holes.
The hole
For basic hole size calculations, use the appropriate formulas for cutting taps.
The component
When the hole is analyzed, have a look at the workpiece material, component shape and quantity.
The machine
The machine influences: Always consider:
Tool holding
The CoroChuck™ 970 is designed for stable and precise tapping in all materials. It improves tap tool life and surface quality, and offers the highest process security.
Application considerations, CoroTap® 100 -PM
Coolant
- Coolant is required
- Not compatible with MQL (minimum quantity lubrication)
- Proper coolant concentration, flow and pressure are critical for effective chip evacuation and maintaining thread quality and finish
- For blind holes, use internal coolant
- Use caution when applying external or through-collet coolant, as it may push chips back into the hole or flutes
- For through holes, use external coolant via collet and/or external nozzles
- If possible, reduce clearance at bottom of hole to
2–3×TP to minimize remnant chips left in bottom of the hole
Machine setups
- No helix on taps to remove chips, so there will always be some remnant of chips existing in the holes
- This can be a better trade off than nesting on the tap causing catastrophic breakages
- Suitable for horizontal setups
- Vertical setups:
- Manual removal of chips may be necessary
- Take action to minimize remnant chips by optimizing coolant, drill depth clearance, and E chamfer version as an alternative solution
- For optimal performance, use a rigid tapping cycle (e.g., Fanuc M29) with rigid or SynchroFlex® holders (e.g., CoroChuck® 970)
