Why it works

Built for Deep, Accurate Core Drilling

Centred, accurate start

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

Adaptor compatible

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

Built for thick walls

The 300mm length reaches through deep or multi-skin masonry that shorter pilots cannot clear.

Trade-grade build

Hardened steel construction built for repeated use on abrasive masonry.

Frequently asked questions

When would I need the 300mm pilot drill over a shorter one?
Go for the 300mm when you're drilling through thick or multi-skin walls - the extra length lets the pilot keep reaching and guiding the core bit even where a standard-length pilot would run out before the bit finishes cutting.

What does the pilot drill actually do?
It centres and guides a diamond core bit as it starts cutting, so the bit doesn't wander off-line and you get a straight, clean hole through brick, block or sandstone.

Which adaptors does it fit?
Both SDS and Hex core drill adaptors, so it works with either fitting without needing a separate adaptor.

How does this compare to the 175mm A-Taper Pilot Drill?
Length is the only real difference - the 300mm is for deeper or thicker masonry where the 175mm can't reach through before the core bit finishes; both share the same A-taper tip and SDS/Hex compatibility.

What materials is it suitable for?
Brick, block, sandstone and similar masonry commonly drilled with diamond core bits.

Does the tip wear out?
Yes - the tip is a wear part on any pilot drill used against abrasive masonry, so it's worth keeping a spare for busy jobs.

Does it fit a specific core bit diameter?
It fits into your core drill's adaptor rather than the core bit itself, so it works across whatever diameters your adaptor supports.
