Overview
Indicating measuring instruments for diameter measurement of conical bores, external cones and direct 45° chamfer measurement. Available in internal taper (IKT), external taper (AKT) and chamfer gauge (KT / KT‑B) versions. Options for mechanical or digital indicators and wireless data transfer.

Internal Taper Gauges (IKT)

• IKT60: for cones < 60° — measuring range 0.5–121 mm (multiple instruments may be required to cover full range)
• IKT90: for cones > 60° and < 90° — measuring range 0.5–120 mm (multiple instruments may be required)
• IKT127: for cones > 90° and < 127° — measuring range 0.5–121 mm (multiple instruments may be required)
• IKT105: special gauge for countersink diameter in rivet holes; 100° angle for aerospace applications — measuring range 0.5–20 mm; zeroing performed at factory or with setting master
• Factory calibration or calibration with setting master available

External Taper Gauges (AKT)

• AKT60: for cones < 60° — measuring range 5–121 mm (multiple instruments may be required)
• AKT90: for cones > 60° and < 90° — measuring range 5–120 mm (multiple instruments may be required)
• AKT127: for cones > 90° and < 127° — measuring range 5–120 mm (multiple instruments may be required)
• Factory calibration or calibration with setting master available

Chamfer Gauges (KT / KT‑B)

• KT: for straight chamfers, external diameters and slots from 16 mm
• KT‑B: designed for bores from Ø28 mm
• Direct measurement of 45° chamfers on rectangular and cylindrical workpieces, including bores and slots
• Standard KT / KT‑B delivered with setting master and factory calibration

Applications & Industry Solutions
DIATEST gauges are designed for precision inspection tasks in industries such as aerospace, automotive and general manufacturing. Instruments provide reliable measurements on flat and curved surfaces; options include industrial radio (wireless) data transfer for process integration.

Example measurement tasks

• Countersink diameter of rivet holes
• Rivet head flushness
• Burr overlap at hole edges
• Rivet hole depth (material thickness)
• Rivet hole diameter
• Other chamfer and cone diameter quality-control measurements

Indicators and Data Transfer
IKT, AKT, KT and KT‑B are offered with shock‑protected mechanical dial indicators (0.01 mm graduation) as standard and can be fitted with digital indicator MDU options (0.01 mm / .0005" or high‑precision 0.001 mm models).
Digital options include:

• MDU‑A125: high‑precision digital indicator, resolution 0.001 mm, freely programmable, real‑time wireless or cable data output
• MDU‑EC125: economical digital indicator, resolution 0.01 mm; angle display via factor input; no data output on the economical model

Measured values can be recorded and transferred via industrial radio (DIAWIRELESS) or cable. Optional IKT‑OS versions are available without stop bars; custom designs and special angles on request.

Technical specifications

• Covered angles: <60°, >60° to <90°, >90° to <127°, plus special 100° (IKT105)
• Measuring ranges: IKT internal from 0.5 up to 121 mm (model dependent); AKT external from 5 up to 121 mm (model dependent); IKT105: 0.5–20 mm
• Chamfer measurement: direct 45° measurement for KT / KT‑B
• Indicator resolution: mechanical 0.01 mm standard; digital options 0.01 mm (.0005") or 0.001 mm
• Calibration: factory or with setting master (setting master included for standard KT / KT‑B)
• Data transfer: DIAWIRELESS (industrial radio) or cable
• Optional configurations: IKT‑OS (without stop bars), custom angles and special designs on request
• Typical applications: countersink diameters, rivet hole checks, chamfer depths, burr inspection and related QC tasks
