Why it works

Built for Deep Core Drilling

Extended reach

465mm length lets the pilot lead all the way through thick masonry and multi-skin walls in a single pass.

Accurate start-up

The A-taper tip keeps the bit centred and reduces wandering when starting a hole in brick, block or sandstone.

Stable drilling

Extra length improves control and stability through deep or awkward-access walls.

Adaptor compatible

Fits SDS and Hex core drill adaptors, so it works with the core rig you already run.

Frequently asked questions

What is an A-taper pilot drill used for?
It centres and guides a diamond core drill bit, keeping the hole straight and accurate as the core bit cuts through masonry.

Why would I need the 465mm length over a standard pilot drill?
The extra length lets the pilot lead all the way through thick or multi-skin walls where a shorter pilot would run out of reach before the core bit finishes cutting.

Will this fit my core drill machine?
It is compatible with SDS and Hex core drill adaptors, so it works with rigs using either fitting.

Does it reduce wandering when starting a hole?
Yes - the A-taper tip keeps the bit centred at start-up, which is where wandering is most likely on hard or uneven masonry.

Can I use this pilot drill with any core bit diameter?
The pilot is fitted to the core drill's adaptor rather than the core bit itself, so it works across the diameters your adaptor supports. Check your core bit and adaptor spec if you are unsure.

Is this a wear part I will need to replace?
Like any pilot drill, the tip will wear with heavy use on abrasive masonry, so keep a spare on hand for demanding jobs.

What materials will this drill through?
It is designed for brick, block, sandstone and similar masonry - the kind of thick or multi-layer walls where a standard-length pilot cannot reach.
