About this part

The ProTek R/C "TruTorque SL" Metric Ball End Hex Driver Set features large 20mm diameter handles with machined relief holes and cross hatch knurling to reduce weight and provide a high grip surface. The end of the handle features a rotating end cap that allows the tool to spin in your palm, maximizing comfort during long wrench sessions. Plus, the tip size is laser etched in not one - but the THREE different spots on the handle to help simplify identification. 

TruTorque SL tools also feature proven HSS steel tips. These tips are precision cut to create an exceptional fit with the fastener, and will continue to hold their edge throughout repeated use. The 80mm long tip is secured in the handle with an M3 set screw, and a full range of replacement tips are available so they are easily replaced if needed.

I have had this set of ball end drivers since April 2020 (now it is September 2020) first time I used the 2.0mm the end broke off and in to three pieces. But I am outside the 90 window so no warranty. It would be nice to get a year out of a out of tool.

Snapped the ball right off on a loctited servo mount screw. Didn't apply a lot of torque but its a hunk of junk now. Other than that, these are pretty nice.

While in the process of performing routine maintenance on my vehicle both the 2.0 and the 1.5 ball end’s broke in the screws I was attempting to remove. I recently purchased these tool and very disappointed in the quality of the tool. The metal appears to be brittle or very weak to say the least.

Broke two tips within a week and one was while using one of the drivers to tighten up the rest….apparently they all have grub nuts holding the shaft to the handle that all shipped loose.

These are some nice ball end driver. They are super light weight. That don’t give you hand fatigue. The handle feels nice and has grip that don’t slip off from you hand.

What reviewers say

Reviewers are sharply divided on this four-piece metric ball end hex driver set. Several one-star reviews report ball tips breaking, including on loctited servo mount screws, a pinion gear and while tightening other fasteners, with some describing the metal as brittle. One reviewer reported that the grub screws holding the shafts to the handles arrived loose. Five-star reviewers praise the light weight, comfortable knurled handle with good grip, and tight tolerances, with one preferring it to MIP drivers. Reviews do not clearly show whether breakage relates to a specific size, though 1.5mm and 2.0mm tips are mentioned most often in failures.

  • + Light weight
  • + Comfortable, grippy knurled handle
  • + Tight tolerances
  • + Good fit compared with MIP drivers
  • − Ball tips breaking under use
  • − Brittle or weak metal reported
  • − Grub screws shipped loose
  • − Poor value for the price
