BIG DAISHOWA MEGA Synchro Tapping Holder

Product system overview

MEGA Synchro is BIG DAISHOWA's rigid-tapping compensation system. The holder is designed to absorb small synchronization errors between spindle feed and tap pitch, while interchangeable tap holders cover ANSI, JIS, ISO, and DIN tap standards in multiple lengths. A complete selection therefore includes both the spindle-side MEGA Synchro shank and the correct tap-holder standard, size, and length.

Industries and applications

• Rigid tapping where synchronization error creates thrust load, thread-quality problems, or shortened tap life.
• Confined setups that benefit from slim nuts and standard short, long, or extra-long tap-holder choices.
• Coolant-through tapping where the spindle-side holder, tap holder, and tap standard need to be documented as one assembly.

Technical and quote details

• BIG DAISHOWA states that the system can reduce thrust loads caused by synchronization error by up to 90 percent; actual results remain application dependent.
• The product family includes spindle-side MGT3, MGT6, MGT12, MGT20, and other available configurations depending on interface and catalog revision.
• Tap-holder choices are organized by ANSI, JIS, ISO, and DIN standards and by length; tap standard and shank dimensions are required selection inputs.
• The system supports center-through coolant on applicable configurations.
• Representative catalog numbers below identify spindle-side holders only; the matching tap holder and accessories must be selected separately.

Selection notes

Build the RFQ as an assembly: spindle interface and MGT shank, tap-holder standard and size, tap catalog number, length, coolant path, thread specification, and machine control.

Check the current product directory and MEGA Synchro manual before substituting holders or accessories across MGT sizes.

Variables to validate

• The shank catalog number alone does not identify the tap holder, tap standard, tap size, projection, nut, adjuster, or coolant arrangement.
• The stated thrust-reduction figure is not a universal cycle result and should be validated against the machine's rigid-tapping behavior and the actual tap.
• Pitch, tap geometry, hole type, material, coolant, speed, and reversal strategy remain application-critical.
