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.
- 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
- 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
Using ballends with a torque wrench or torque handle,
reduces the chance of breakage and greatly extends the useful
- 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.
- 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®
- 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.
