DEEP LASER ENGRAVING SERVICES
Deep laser engraving (or laser drilling) is a superior drilling method that surpasses the limitations of a mechanical process and a round drill bit. Laser drilling is a cost-effective fabrication process for a wide range of materials and components used in the aerospace/space, military, defense, medical device, automotive, and commercial industries.
When you think it can’t be done, think again.
Our laser drilling services make the impossible a reality.
Need Square Holes? No Problem.
When it comes to square holes and complex geometries laser drilling is the only way to go.
- Laser drilling isn’t limited to what a drill bit can accomplish
- Varied depths and shapes are all achievable
- Much lower tolerances than any other deep engraving or drilling method.
Laser Drilling Is Inexpensive, Fast And Precise
Laser drilling is the most cost effective way to accomplish precision deep engraving.
- No upfront tooling costs
- With a kerf of just .002” inside corners and fine details are no problem
- Plus, the small spot size easily accommodates hard to reach areas
Laser Drilling Is The Better Method
Laser drilling services have another benefit—no chemicals or mechanical tooling challenges to overcome.
- Deeper, cleaner cuts means high resolution is possible like never before.
- Perfect for high quality finishes—since there is no contact with the material, it leaves no tool marks
- List of materials that qualify for laser drilling
Why work with Rache Corporation?
We have decades of experience and we bring that hard-earned knowledge to every project.
“We have been pushing Rache’s manufacturing limits to the fine points of what can be done with a laser, trying to see just how small can you really get and still hold the spec. Rache engineers never over-promise, they are always up front about what they can do — repeatedly produce very small, precise rectangular holes. They make my job easy because they are easy to deal with.”

Overcoming Challenges of Cutting KovarⓇ And Nickel Alloys
Rache Corporation Thin Kovar® Laser Cutting
Conventional machining techniques of Kovar® (ASTM F15 alloy) in thicknesses from .010” to .100” have always been a challenge. Nickel alloys harden quickly, and the high pressures that machining creates causes hardening and slows down the process. Tools have a tendency to plow through Kovar® rather than chip away at it and the material tends to gum.
Holes must be frequently cleaned to remove chips that will gall and machinists develop their own machining techniques and documenting the process is somewhat subjective.
When machining Kovar®, keeping the machined area cool is a must to minimize warping of the material. Diligent tool wear inspection is also a must. Drilling / reaming requires constant attention.
Sulphur in the cutting fluid may degrade the Kovar’s magnetic properties and could cause grain embrittlement.
.025” Thick Kovar®
Over 30 years ago, Rache Corporation developed a laser process that produces thin-metal shapes at a lower cost than conventional machining methods and cutting Kovar® is one of our specialties. Our electronic / microwave customers are pleased that they can now utilize this laser cutting option especially in the critical delivery pre-production prototype phase.
