Stop Compensating. Start Cutting.
If you’ve drilled carbon fiber, you’ve seen it before.
The entry looks clean.
The top looks good.
Then you flip the part… and the exit is gone.
Delamination. Fuzz. Scrap.
So what do you do?
Slow it down.
Add peck cycles.
Reduce feed rates.
Now a 3-second job takes 15 seconds plus.
The Real Problem Isn’t Speed—It’s Force
Most drills push through material.
At breakthrough, CFRP has no support left—so instead of cutting cleanly, the tool forces fibers outward, separating them from the resin.
That’s what destroys the exit.
Now add stack materials:
- CFRP + Aluminum
- CFRP + Titanium
And it gets worse—hot metal chips re-enter the hole, damaging walls and killing tolerances.
You Know the Signs
- Crunching at breakthrough
- Bird nesting on the tool
- Peck cycles just to survive
- Fuzz that needs a second operation
This isn’t just tooling.
It’s physics.
A Better Way to Cut
The Wave-Point® Drill by Sharon-Cutwell changes how the cut happens.
Instead of pushing through material, it pulls fibers into the cut.
Its patented “wave” geometry:
- Breaks the cutting edge into stages
- Controls the material during breakthrough
- Distributes cutting forces across multiple points
The result? A controlled, clean exit—every time.
What It Means on the Floor
- Higher feed rates without delamination
- Clean entry and exit holes
- No fuzz or uncut fiber
- Stable performance in CFRP/Al and CFRP/Ti stacks
- Reduced or eliminated peck cycles
- Longer tool life with CVD diamond coating
The Result
No more programming around the problem.
No more:
- Slowing feeds
- Adding peck cycles
- Secondary cleanup operations
- Stopping to clear chips
Instead, you get:
- Consistent hole quality
- Predictable cycle times
- Faster throughput (as low as ~3 seconds per hole)
- Reliable performance in abrasive materials
Bottom Line
If your process is built around avoiding damage…
you’re already losing time.
Stop compensating. Start cutting.
