Sustainable Bolting and Bolt Removal



Hole cleaning brushes and blowers are essential for goood bolt placement.

Failing to clean the hole properly can lead to massive reductions in holding power, whether it is glue or bolt-ins. For a test of this look at Strength and Tests

Core Drills- these are specially imported diamond core drills for drilling out old bolt stubs to allow new bolts to be fitted.

As you can see they are expensive, but they do the job where nothing else will.

Core Drills

The only effective way to remove old bolt stubs and leave a usable hole, these are the highest specification sintered diamond core drills in the world with a life 20X longer than electroplated drills.(electroplated drills have a single layer of diamonds held in place by electroplating, sintered drills have a metal/diamond matrix bonded to the drill under high pressure and temperature).

With a 2mm wall thickness these are the only suitable drill we can find for drilling up to 9,5 Mohr hardness for drilling quartz, granite, sandstone etc, normal electroplated drills are for use up to 5 Mohr and cannot drill ultra-hard materials.

These drills drill to a depth of 76mm, suitable for nearly all older bolt systems (most "normal" core drills only go to ca 50mm). Longer drills are available if required- please contact us for details.

Made in America for use with a hand held drill they require some water cooling, the normal high pressure centre feed is totally impractical and we supply an external feed adaptor which fits onto a standard drill handle and depth guage. This is supplied with water from a pump-up garden spray.

After the bolt is removed the drill hole must be re-drilled with a normal tipped drill to roughen the surface as these core drills leave a rather smooth hole and also are imperial dimensioned though for glue-ins this is irrelevant.

We normally keep three sizes in stock to suit the most common bolts you will meet but can order other sizes if required,

We operate a hire scheme if you are re-equipping with Bolt-Products bolts, this includes a battery powered angle grinder for hanger or eye removal if required.

These are only to be used in rotary drilling NOT hammer action.

Drills are supplied complete with an adaptor to fit a standard 1/2"/13mm chuck.

If your drill has only SDS you will need an SDS adaptor and normal drill chuck to fit these core bits. These are available in all good tool shops.
