■ Precautions when Using Wiper Inserts with Holes ● When assembling the wiper insert, attach it as shown in Fig. 1. When attached as shown in Fig. 2, normal machined surface roughness cannot be obtained.
● Wiper inserts are single-cornered and double-sided. ● Refer to Technical Guidance page N19 in the General Catalogue for details about wiper inserts. ● Do not use with DNHS and DNH types.
