Indenter Types and specs.:
 

• Rockwell Diamond Cone Indenter:with a cone angle of 120 degrees and a top spherical radius of 0.2 mm. (applicable to HRA, HRC, HRD, and HRN scales);

• Rockwell WC Ball Indenter:with a ball diameter of 1.588mm(1/16'),applicable to HRB,HRF,HRG and HRJ scales;

• Plastic Rockwell WC Ball Indenter:with ball indenter diameter of 3.175mm(1/8')for HRE, HRH, and HRK scales;diameter of 6.35mm (1/4')for HRL and HRM scales,;diameter of 12.7mm (1/2')for HRR scales;

• Brinell WC Ball Indenter:with ball diameter of 10mm,5mm,2.5mm,1mm;

• Vickers Diamond Square Pyramid Indenter:with an opposite angle of 136 degree;

• Knoop Diamond Square Pyramid Indenter:with an opposite angle of 130 and 172.30 degree;

• Shore hardness Diamond indenter(Symmetrical Punch):with a spherical radius of 1.0 mm at the top;

• Leeb hardness impact body:made of tungsten carbide and diamond,wxcept E-type impact body made of diamond, other types are made of tungsten carbide. There are six types: D, DC, D+15, G, E, and C. While the G-ball is set to 5mm, other balls are 3mm.

Suitable hardness machine for diamond indenter:

• Rockwell Hardness Tester(rockwell diamond indenter in HRC,HRA scales).
• Vickers Hardness Tester(vickers indenter HV2,HV6).
• Micro Vickers Hardness Tester(knoop intender).
