Flush Hole Finishing

We provide clean, burr-free countersinks compatible with industrial fasteners and aerospace standards.

Precision Angularity

Precision Angularity

Maintain strict 82° and 90° angles for perfect fastener alignment and flush seating.

Consistent Depth

Consistent Depth

Automated depth stop controls ensure every countersink is identical across large production runs.

Burr-Free Finish

Burr-Free Finish

Optimized tool speeds and feed rates prevent edge rolling and exit burrs on sensitive materials.

Design for
Flush Mounts

Proper countersink geometry is critical for fastener load distribution. Follow these safety rules.

C1

Head Diameter

The countersink major diameter must be at least 0.2mm larger than the screw head diameter.

C2

Minimum Thickness

Unprotected countersinks require material at least 1.5x thicker than the countersink depth.

C3

Hole Preparation

Holes must be pre-drilled or CNC cut before countersinking to ensure concentricity and finish.

The
Finishing Path

Our configurator identifies hole geometries and calculates tool depth automatically during the quoting process.

Process Visualization
01

Fastener Selection

Upload your CAD. Our system detects holes and prompts you to select fastener type (SAE vs Metric) and desired fit.

02

Tagging & Limits

Indicate which holes require countersinking. Our engine instantly checks material thickness against depth limits.

03

Automated Tooling

Once confirmed, the design is queued for our automated countersinking stations where depth is strictly controlled.

Mechanical Perfection

Flush surfaces for your assemblies.
