Feature(may vary by option.)

●[SIZE] - 4mm bore 8mm thickness drill stop. Hex wrench is included to help adjust and install the stop rings.
●[MATERIAL] - Strong and durable steel with black-oxide finished for better corrosion-resistance. Set screw type will stay sturdy when tightened and is specially designed not to break the bits.
●[ADJUSTABLE] - Drill stop bit can be quickly and easily adjusted at any point on drill bit flutes, helps to drill holes to exact depths, prevents under and over drilling.
●[APPLICATION] - Set-screw type drill stop is suitable for low axial loads and simple positioning. It is great for jobs that use a bit and need precision.
●[NOTICE] - For maximum holding power, make sure the set screw material is harder than your shaft material. Do not move the drill bit stop after tightening.

Feature

  • Set-Screw type drill stop is suitable to use on a shaft softer than the set screw.
  • Slide the stop ring onto an unhardened shaft and tighten the set screw, the set screw would bite into the shaft and hold it.
  • This type of drill bit stop features great torque capacity and holding power.

Notes

  • In order to maximize the holding power, the shaft must be softer than the set screw.
  • Tightening the set screws will cause damage to the surface of the shaft, which is an inevitable disadvantage. Please do not move it after locking. To prevent this, small flats are often added under the set screw.

Application

  • The drill stop is suitable for low axial loads and simple positioning. Applications that require repositioning or high axial loads are not applicable.
  • Can be used to limit the movement of a shaft and retain power transmission components such as sprockets, pulleys, and bearings.
