Note 1) Select and use an alternate shim from list below (sold separately), dependant on the lead angle.
• The screw-on type has no shim. The holder has an in-built lead angle. Please select a holder with the appropriate lead angle.
• The minimum cutting diameter (DMIN) indicates the prepared hole diameter, not the nominal thread diameter.
* Clamp Torgue (lbf-in) : TS25=8.9, CS350860T=31, SETS51=31, TS43=31, SETS61=44, HFC03006=13, HFC04008=19
