Made of tough high speed steel, these bits are ideal for mounting bindings.
They fit any mounting jig, are a full 3" long, and will countersink the screw holes so you don't "bubble-up" the top ski surface when you tighten down the screw.
Drill bits are sold individually.
FOUR OPTIONS AVAILABLE (first number indicates diameter, second indicates depth)
3.6 x 9mm bit is best for most adult alpine skis.
4.1 x 9mm bit is for metal laminate alpine skis or those with a metal or titanal mounting plate internally located in the ski.
