Improve Drilling Cycle Times in Aerospace Assembly
Sifer Srl, a leader in technical drilling solutions, has launched Easyfit, a new generation of temporary fasteners and drill jig technology that redefines efficiency in advanced aerospace drilling processes. Good news, particularly for aerospace processes.
The advantages of the Easyfit technology are major:
- fewer hardware components
- simplified setup
- superior hole quality
- eliminated interference issues,
Saving time and money, and increasing productivity.
With EasyFit, the use of temporary fasteners is dramatically reduced—often by greater than 50%, and in some cases, more. This impressive reduction is accomplished with Sifer’s patented temporary templates and fasteners, plus meticulous torque control. The result is an optimized, rigid clamp of jigs and panels throughout the drilling application.

Accelerate Drilling Aerospace Assembly Quality Holes
Save on materials and costs. Boost aerospace drilling application times:
- EasyFit dramatically reduces the need for temporary fasteners by more than 50% (sometimes more) in most aerospace applications – offering substantial material savings
- Precisely monitored and regulated torque – ensuring an even and optimal clamp load that enhances consistency across every drilled hole.
- Faster process times by minimizing the number of hardware components required
- Productivity gains – streamlined workflow and reduced rework with less time on fastener setup
- Superior hole quality by reducing common defects and inconsistencies typically associated with conventional drill jig setups.
- Solid clamping eliminates interference issues that often arise with legacy temporary fasteners
- Optimized double clamping. The patented Easyfit temporary fastener clamps the jigs and aircraft panels for maximum control.
- Rigidity without deformation when Easyfit fasteners are inserted in the Lübbering A.D.U.-drilled holes.
- Perfectly managed torque with multiple sizes of Easyfit fasteners
- One screwdriver for all fasteners with torque settings stored internally for consistent application
- Works with Lübbering L.ADU and other concentric collet systems.
