Manual Gauge Point Punches

Gauge point punches are used to punch mark a metallic specimen with a set gauge length before testing so that specimen elongation can be measured either during or after the test. Manual punches are available for a range of different gauge lengths.

0.5 in	W-6718
Combination Gauge Point Punch: 1 in and 2 in	W-6771
Combination Gauge Point Punch: 25 mm and 50 mm	W-6771-B
1.4 in	W-6719
8 in	W-6714
Extra Punch Points — Set of 2 Suitable for 1 in, 1.4 in, 2 in, 25 mm, and 50 mm gauge point punches	W-6709
Replacement Punch Points — Set of 2 Suitable for 8 in gauge point punch	W-6704

Punching Machines — Specimen Preparation

These machines are developed to obtain specimens by punching, using hollow dies of different sizes and contours. Several hundreds of dies can be created by interchangeable socket punches with different profiles and size according to the standards and the application needs. Dies are made of steel with hand-finished cutting edges and can be provided with an ejector for easy removal of the specimen after punching.

Create specimens for testing to the following standards: ISO 2818, ISO 179, ISO 180, ISO 8256, ASTM 6110, ASTM D256, ASTM D412, ASTM D638, and DIN 53453.

Notching machine for specimen preparation

Notching Machines — Specimen Preparation

Notching machines are designed to notch specimens for impact resilience according to Izod, Charpy, and tensile impact methods. These instruments use a linear knife-cutting technique to avoid overheating and consequent stresses during the specimen's notching operations. Therefore, accurate notch preparation is guaranteed.

Create specimens for testing to the following standards: ISO 2818, ISO 179, ISO 180, ISO 8256, ASTM 6110, ASTM D256, and DIN 53453.
