SYNCHRONIZED TAPPING HOLDER (for 100% Synchronized Feed)
Synchronized (Rigid or Direct) Tapping Feed Function is one of recent machining function to feed 1 pitch of tap per 1 revolution of machine spindle. Please use High Run-Out Accuracy & Powerful Gripping of SLIM CHUCK or MULTI LOCK Milling Chuck for this application. Tapping holder & Collet for 100% Synchronized Tapping

★ Tap Collet for Tap with Oil Hole is also available. ★ At use of MILLING CHUCK, please use tap with shank tolerance h7. ★ By compatibility with tap, material, cutting condition and so on, the cutting resistance may increase and slip even when gripped with a collet chuck. In that case, please contact us separately.

★ F is calculated by Pitch of Tap and Spindle Rotation Speed. For example, in case of M10 × P1.5 and S400r/min (Cutting Speed 12.6m/min.) then F = 1.5mm × 400r/min = 600 mm/min.
