PERF-ARC VERTICAL TUBE PIERCING UNITS

Frequently Asked Questions

--------------------------------------------------------------------------------

Will these tools pierce clean holes?
Clean hole piercing (no deformation to OD) can not be done with Perf-Arc tools. In order to prevent tube deformation, we will typically custom design and build a tool in a die set, with a mandrel to support the tube ID. Because of the custom nature of this type of equipment, please contact us and supply a print of your part so we can accurately quote an appropriate tool. [Click here to see a typical mandrel (arbor) piercing die].

How much dimple can I expect?
It's the question we get asked most. The amount of dimple these tools produce is based on many factors, including hole size in relation to tube ID, weld seam location, tube material and gauge, tooling sharpness, press speed, amount & type of lubrication used. For this reason, we cannot estimate the dimple you can expect. These tools are perfect when the exact amount of dimple is not critical and variation in dimple (i.e. as tooling dulls) will not impact part function, such as clearance holes, bolt holes,etc.

TYPES OF PIERCING

--------------------------------------------------------------------------------

These units are self-contained, mounting of the base is all that's required.

The lower clamp includes an integral bushing sized both to your hole size and tubing gauge. 

Each unit includes a perforator and a pair of clamps sized to your tube, up to maximums shown below..

PERF-ARC SELF CONTAINED UNITS
  Self contained units are the easiest to set up requiring only mounting of the base of the unit.
DIMPLED HOLE ONE SIDE CLEAN HOLE OTHER SIDE
Please specify: tube size, gauge and hole size required. Units may be ordered for round, square or rectangular tube sizes up to max. capacity of each unit. Exit hole (bottom wall) will be deformation-free however this hole will be up to 25% of the tube's wall thickness larger, due to slug clearance, (i.e. for 16 gauge, exit holes are up to .016" larger)
