Chamfer Gauge
The internal taper gauge measures the largest diameter of a conical bore or a conical keyway. An IKT replaces previous slower and more expensive gauging methods.
Measuring surface and hardened steel taper
Scale graduation of indicators: 0.01 mm
Calibration at factory or via setting master
Special designs on request
Direct gauging of major diameter of internal tapers or tapered slots
Models with 60°, 90° and 127° taper
Application range: ? 0.5 mm to 120 mm
Measuring range: 11.5 mm for 60° taper/19.5 mm for 90° and 127° taper
The low-cost Alternative: The Internal Taper Gauge IKT-OS
 
The term OS is an abbreviation which means “without stop bar". By the omission of the bar, the alternative internal taper gauge can be manufactured at a lower cost which in turn renders a favourable sales price.
 
The IKT-OS is implemented to measure the largest diameter of internal tapers or tapered grooves. In contrast to its brother product, the IKT-OS requires a contact surface and cannot be used with thin-walled work pieces.
 
Available in the following models:

IKT90-1-OS Measuring range 0,5-20
IKT90-2-OS Measuring range 20-40
IKT60-1-OS Measuring range 0,5-12
IKT60-2-OS Measuring range 10-21
IKT127-1-OS Measuring range 0,5-20
 
Standard setting masters can be utilised, as well as the corresponding dial indicator or digital dial indicator IKT-MU1086W.
 
Available on request.

External taper gauge (AKT)
Direct gauging of minor diameter of external taper
Models with 60°, 90° and 127° plungers
Application range: ? 5 mm to 120 mm
Measuring range: 11 mm for 60° plunger/19.5 mm for 90° and 127° plunger (except for size 1)

Chamfer gauge (KT/KT-B)
Direct gauging of 45° chamfers on rectangular and cylindrical pieces, even bores or slots
Measuring range: chamfers up to 7 mm (radii 1 mm up to 9.5 mm via conversion)
Chamfers in bores from approx. ? 28 mm
 
Dial indicators for chamfer gauges

The chamfer gauges require specially adjusted analogue dial indicators which are adapted to the respective angle.

The freely programmable digital dial gauge MUM1086W allows to set any special angle for IKT devices apart from the standard angles. All measuring results can be transferred and recorded via digital data transfer.

Data can be transferred via cable (USB and RS232 to PC; or with digimatic) or by DIATEST real radio transmission. Here measured values can be transmitted outdoors up to 200 m, inside buildings the maximum range is 20 m. The data security is very high.
