Sharon Cutwell - Driving Precision in Hydraulics

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. Learn How Custom tools from Sharon-Cutwell can improve your productivity and results.

In manufacturing, the final finish isn’t just cosmetic—it’s critical to performance, fit, and reliability. The Challenge Traditional deburring tools often: Remove too much material Wear inconsistently Create variation from part to part Require manual rework And in today’s world of tight tolerances… that’s a problem. The Solution The E.S.S. Contact™ Brush is built with proprietary ceramic extruded fiber technology , delivering: Surface-safe deburring without damaging critical features Consistent, repeatable finishes across every part Flexible cutting action that adapts to geometry Long tool life with predictable performance Where It Performs Perfect for: CNC-machined components Aerospace & medical parts Precision metalworking Surface blending & polishing Handles tough materials like stainless, titanium, and hardened steels—without compromising finish quality. Why It Matters The Contact brush transforms finishing from a manual cleanup step into a controlled, repeatable process . Less guesswork. Less rework. Better results. Delivering Solutions At FactoryLink, we don’t just offer products—we help you optimize your entire process . Because finishing isn’t an afterthought… it’s part of the system. Learn how you can optimise your finishing process!
