Since its introduction, the OlyLog has changed the way log homes are constructed. Here's why: No Predrilling! The OlyLog® zips right through all species of logs. Self Countersinking head design:Buries itself below the log surface and allows for natural log settling. Removable: Just put the drill in reverse and back it out. Strong pull down power, no sledge hammer damage, greatly reduced labor time, 100% American Made.
