Yes, Our Tapping Chucks with safety clutches are very reliable and tap will stop rotating as soon as it touches to the bottom, because of safety ball clutch mechanism.

Q.3] Many times we find oversize threads and Bell mounted too. What are the reasons for correction?

  • Misalignment
  • InCorrect feed rate
  • Incorrect pre-drilled Hole
  • Tapping Device or Machine faulty
  • Insufficient or Incorrect Lubricant
  • Incorrectly ground or eccentric Tap
  • Wrong tap Selection

Q.4] Many times we find damage to the start of the threads?
Slow return feed causing the full compression of the length compensation while the tap leaves the workpiece.

To correct this Increase the feed for the return movement, so that the tap leaves the workpiece when the length compensation is extended.

Q.5] The tap holder length compensation acting on compression is compressed before the tap starts to cut?

  • Tap is blunt or damaged
  • Tap drill hole is small or of insufficient depth
  • Burrs clogging
  • Torque setting too low
  • Incase of KWFLK series Adj. Screw setting improper
    • For Best Results
    • Use ‘KTA’ Tapping Chucks
    • Choose correct lubricants, use the correct type of tap for the job, use correct drill size
    • Choose the correct speeds and feeds, keep taps sharp, ensure thread guages are recently certified, they do wear.
