Tap holders and accessories

With the HST SYNCHRO program we provide tap holders, also suitable for HST machining, which are especially designed to match your requirements. BASS tap holders in combination with BASS threading tools represent an unbeatable tandem for highest efficiency in the production of internal threads.

Our tap holders compensate errors of the hole centerline spindle rotation and the feed axis. With their specially designed and patented damping, they guarantee a micro-compensation of the feed axis. They are washable up to 80 °C.

Our types

HST SYNCHRO

Our tap holder for standard applications is available in different sizes

Besides straight and HSK-shank we can offer further shank types upon request.

HST SYNCHRO MMS

Our tap holder for minimal quantity lubrication in combination with our MQL threading tools avoids accumulations of the lubricant. This ensures that the lubricant reaches the tool operating area.

HST SYNCHRO QCA

While conventional quick change systems and holders have a large radial play our QCA was especially designed for the use in the HST SYNCHRO tap holder.

The total length can be continuously adjusted from 100 mm down to 60 mm by shortening the straight shank.
