Kannen jigi

Those hardened-steel drill guides keep the bit dead-on straight every time, which made a huge difference on my long run of boards. I've used cheaper jigs that wobbled, but this one feels solid and the handle gives you real control. My deck joints all line up perfectly now.

The hardened-steel guides kept the bit perfectly straight on every board I laid, so the seams lined up without any fuss. Even after a full afternoon of work, the handle stayed comfortable and gave me the control I needed for tight joints.

The easy-grip handle really does make a difference—my hand never slipped even on damp boards. Spacing and alignment turned out spot-on with the stepped bit, so the whole deck went down in one weekend.
