Manual Gauges for Countersinks and Depths


Marposs offers solutions to manually measure the principal characteristics of bore lip countersinks and the depth of blind bores or spot faces.

These customisable solutions, available in mechanical, electro-mechanical or wireless versions, are compatible with all measurement processing and display devices. 

Manual Gauges for Countersinks and Depths

Marposs offers solutions for measuring the principal characteristics of bore lip chamfers or countersinks (Countersink Gauge): maximum diameter of tapered bore, countersink depth (arrest depth of a sphere at known diameter), and, by combining the measurement data, taken using two different instruments, in an electronic processing unit or PC,  countersink angle can be calculated. It is fundamentally important to control these variables in the case of assembly using rivets, for example.

A Countersink gauge consists of a  conical or spherical shaped contact, a tripod, that establishes the reference plane, and a precision mechanical movement that guarantees accurate measurement results.

A cylindrical contact version may be used to measure the depth of a blind bore or spot face.

Due to a wide selection of handles (with built-in analogue or digital comparator, hard-wired or wireless, with or without display), the gauge can be  configured to fully satisfy the user’s requirements.

  • optimum metrological guarantee when carrying out manual checks on any measurable quantity
  • intuitive and easy to use: the design, that guarantees linearity throughout the measurement range, may be reset using a single master
  • designed and built to withstand impacts
  • the tempered steel contact guarantees high resistance to wear and corrosion
  • may be connected (hard-wired or wireless) to any type of processing or display device (commercial PCs or Marposs industrial computers) in order to satisfy every requirement
  • may be used to transmit and save the measurements to an industrial pc for subsequent statistical analysis
  • components are designed to guarantee serviceability and repairability
  • interchangeable contacts and tripods
  • tempered steel contacts and tripods 
  • linear application range
  • conical Master with certification
  • special reinforced cable with Lumberg SV50/6 connector (available with the cable version)
  • pre-programmed Quick Digit  indicator
  • compatible with Marposs and other manufacturers’ electronic units

Countersink gauge with conical  contact:

  • with digital indicator (also available in Bluetooth version)
  • hard-wired
  • wireless with or without display

Countersink gauge with spherical contact:

  • with mechanical or digital indicator (also available in Bluetooth version)
  • hard-wired
  • wireless with or without display

Depth gauge with cylindrical  contact:

  • with mechanical or digital indicator (also available in Bluetooth version)
  • hard-wired
  • wireless with or without display
