Premiere ball end tools

It’s no accident that Bondhus is recognized the world over for quality tools. Bondhus invented the ball-end, and continues to produce products unmatched in quality, machining, and durability, even in the smallest ball sizes. Engineering and manufacturing skills, coupled with a sales and support staff second to none, has made the name Bondhus synonymous with quality.

 Ballend Considerations:

  • Ballends provide very fast insertion into screw heads, even from an angle, or when working in the blind.
  • Screw-holding technology, such as Bondhus® ProHold® tip, is a dramatic improvement in the utility of ballend tools.
  • The concept by which ballends slide into a screw head is known as funnel insertion. Basically, it means that the sides of the ballend direct (funnel) it into place.
  • A ballend can be used in a power driver, and even at 500 RPM, funnel insertion will radially twist the ball into position and seat it in the screw head.
  • Quality ballends seat to full depth in a screw, and are no more prone to stripping than a straight blade.
  • A straight hex blade may have greater torque capacity than a ballend, but a ballend is far more efficient.
  • A high quality ballend is capable of generating the recommended seating torque for most screws, but care should still be exercised to not over-torque a ballend.
  • Due to its many advantages, a ballend is a tremendous timesaver.
  • Star ballends wear more rapidly than hex ballends, due to the star having less contact surface.
  • Operators can feel when a straight blade begins to ‘yield’, but ballends break without exhibiting any telltale warning signs.
  • Using ballends with a torque wrench or torque handle, reduces the chance of breakage and greatly extends the useful bit life.
  • A good rule of thumb is to set the torque level to about 20% less than the capacity of the ballend.
  • The maximum torque capacity, and the allowable working angle permitted by the ball are major factors to consider when evaluating a ballend. Increasing working angle decreases torque capacity, and increasing strength increases neck size, and thus decreases working angle.
  • As maximum allowable angle increases, neck size decreases, and strength also decreases. By contrast, increasing the strength of a ball-end tool requires a corresponding increase in neck size and decrease in maximum allowable angle.
  • Designing the perfect ball-end tool means choosing the ideal balance between strength and allowable angle.

Bondhus® Advantages:

  • Protanium® Steel is used in the manufacturing of all Bondhus® tools.
  • Protanium® Steel achieves levels of hardness, ductility, and wear unmatched in the industry.
  • ProGuard™ dry surface finish is standard on all unplated Bondhus® tools.
  • Bondhus has the most comprehensive lineup of handles, blades, bits, and packaging options available.
  • Exceptionally high quality machining means:
    • Tools fit better, so they last longer.
    • Engagement in screw heads is positive and stable.
    • Fastener heads exhibit less wear.
    • Stripping and breaking is noticeably reduced.
  • All Bondhus® ball end tools are carefully matched with handles of consistent torque capacity. Bondhus does not manufacture tools with handles capable of over-torqueing their blades!
  • Bondhus® ballends provide very fast insertion into screw heads, even from an angle or when working in the blind.
  • Ball end tools with or without ProHold® tips, are available in hex, star, and square tips.
