CTR, RTR Rubber Tip

Conical & Rectangular Tip Rubber

The black nitrile rubber (NBR) is, since the beginning of chip assembly, an appreciated material to produce replaceable tips. Despite the emergence of other materials ( see our PCTR, BPCT or FCTR), the rubber has conserved properties giving satisfaction and flexibility.

The range of available sizes starts with a minimum size of 008x008 up to 470x470 mils.

Every type is build from a family of 4 distinct types identified as:  A B C D.

The types A and B are compatible with the shank having the square insert type A/B while the others are compatible with the shank with square insert type C/D.
