Large Drill bit for steel rod bracing approx 1.5m trunk

[Tommy O]

Hi does anybody know anywhere you can purchase very long drill bits to drill through a tree so that I can put a steel rod brace in. Tree Diameter probably just under 1.5m . 
thanks

What diameter, and what length? Not difficult to find 600mm long auger bits. Screwfix do 300mm extensions for them, at about £8 each.

Maybe need to get creative with some steel bar, buy a long auger bit and Loctite an extension on. I've extended drill bits with high strength Loctite, its plenty strong enough to pass the drive of a drill.

 

Otherwise the green oak framers probably have tools for this but guess expensive.

From past experience of boring a 25mm hole in some oak at a depth of 550mm, it wernt good to do but i was going with the grain, i think across the grain would be easier, use plenty of candle wax on the auger bit and for gods sake keep pulling the auger out to clean the hole out or it gets blocked up and the auger goes solid, (had to split one length of timber to free the auger) and take your time as i burnt a £140 Boch SDS drill out after 2 holes,,,,

Could you weld some stud iron onto the auger bit. Might just survive a one off job. I would imagine 1.5m drill bits would be very expensive

Tree stuff in America has what you need , the only problem is you have to pay import duty, but it was the only place I could find an auger big enough for a monster splitting beech we rod braced back together.

Just buy the auger price it into the job. if you win you get auger for next job, 

trying to bodge an auger to drill that  will only end in tears, if it comes apart half way through the whole just how are you getting it out, you will need a pretty hefty drill to power it I get mine from Swiftfix in Southampton 02380446644

they can make any size you want up to 2.4 metres In length

An SDS is totally the wrong drill for the job. You need a low geared high torque drill like oak framers use. I have the Milwaukee variant.

Thats ok but wouldn't the SDS Milwaukee Fuel ( that I have ) M18 CHD be better . The Hawg has a key chuck where as the SDS Max fitting would not slip . ?
