I bought a 13 piece HSS hex bit set to put in my bag to find a refurbished 18 volt pistol style screwdriver that is fully drillable and even has a setting for it on the swivel adjuster. This kit allowed me to use a screwdriver and drill a pilot hole instead of installing two tools, but these titanium hex bits break easily when used with a hand drill. In the future I will avoid titanium bits and just go back to using my drill, hammering in a regular bit and not breaking my bits as regularly as I do with these "hardened" titanium bits. Not worth the grief of a click indicating another racquet has broken in use. I hope this helps you avoid the heartache of drilling despair.
