Dressing diamond bits

[shanky887614]

haha very true! but you'll give some of the old boys on here a heart attack if they see you using sexual innuendos

? you mean your family is very prude?

mine must be the opersit.

at my grand mothers wedding (in her 60's) everyone was singing along to suzie bear and worse songs, that was before a couple bikers went onto the dance floor in the nude on there harleys

Just bought some MARCUIST core hole drills these are designed to be used on hammer as someone used my new core hole set for about 8 holes over 4 days & totally f....d it, also the other day we used a core hole drill HILTI & HILTI BIT & done about 20 holes in about 4 hours very good machine & core BIT, we did also get the BIT re-toothed at cost of about £120.00 but this had done loads of core holes before hand.

I've been slipping it in and out for the last 2 days and it's goin quite well. Most are 5 1/2 inches but I did manage an 8 incher today lol

A handy tip, especially for bigger cores is to core out approx. 5-10mm deep. Then get a 5mm SDS bit and stitch drill as many holes as you want/can around the circle. Then crack on core drilling again. Reduces wear on the core. I use the same technique on timber with routers and jigsaws, as router bits can be expensive also.

But why oh why are you coring 28mm holes... Just get a big SDS drill bit out! You are far too professional for my liking mate! :smiley2:

why not do what the site boys do though, drill in 10mm from outside with core bit then use the clump hammer & just smash through apparently saves loads of time

Yep, I do that occasionally also Marc. Usually if the brick is rock hard though, and I normally core to around 30-40mm first, so when drilling for wall plugs there is less chance of having nothing to drill into. If it's soft brick and the weather is nice I would probably just stay coring!
