Notes

TS-ioo sink depths at which the full feed values can be maintained

during chamfering and machining. TS8o max. sink depths that can be achieved without chipbreak

cycles and at a 20% feed reduction. TS_max max max. sink depths that can be achieved without chipbreak

cycles and at a 50% feed reduction. TB_mi_n min. drilling depth that can be achieved due to the protrude

length of the drill.

TB_max max. drilling depth that can be achieved due to the protrude length of the drill.

Order example:

(SEFAS compact tool for drilling diameters of 4.0 to 6.0 mm)

3.37060R720 Included:

Compact tool with suppliers of clamping elements and wrench.
