CARATTERISTICHE: Similar to an SFM metric renewable bush, but with specially designed chip-breaking notches on the drill-exit end. Use to break up chips from tough, stringy materials, to reduce friction and heat buildup. Reduces bush wear at the drill-exit end and reduces the chance of tool or work piece damage. A chip-breaker bush should extend beyond its liner to allow chips to escape. Chip breakers are also available on other bush types such as PM and HM.

MISURE STANDARD: see Dimensions page for part numbers and standard ID drill sizes. The prices shown apply to standard bushes only, with any standard metric ID size within the stated range.
