Carrier-mounted percussion drilling
Turn the excavator already on site into a drill, seven CPA attachments covering 26 mm to 127 mm holes at depths up to 30.9 m.
Montabert's CPA range converts a standard excavator into a versatile drilling rig, eliminating the need for a dedicated drill on smaller jobs and the cost of mobilising a second machine. Seven models scale from the Micro CPA (9 to 12 tonne carriers, 26-76 mm holes at 3.2 m depth) up to the CPA 35 160 (28 to 40 tonne carriers, 64-127 mm holes at 30.9 m depth). Used across blasting preparation, cliff and embankment bolting, tunnel ceiling reinforcement and trench drilling. Distributed in Australia by Monty Products.
From Rig to Attachment
No dedicated drill, no second mobilisation, no extra operator. The excavator already on site does the drilling between digs.
Wide Diameter & Depth Range
Holes from 26 mm to 127 mm and depths from 3.2 m to 30.9 m across seven models, the right spec for blasting, bolting or production drilling.
Production-Class Drilling
CPA 30 and 35 series deliver drilling performance comparable to dedicated rigs, mounted on a carrier you already own.
Range Spectrum
Maximum drilling depth (m)
Where each CPA model sits across the range, shallow utilities work on the left, deep production drilling on the right.
Where It Works
Common applications across Australian construction, demolition and civil sites.
Pre-splitting & blasting
Drilling pattern shots ahead of blasts on quarries, civil cuts and surface mining benches.
Cliff & embankment bolting
Rock anchor and bolt installation for slope stabilisation and retaining structures.
Tunnel ceiling reinforcement
Roof bolting and ground support inside tunnels and underground excavations.
Trench drilling
Pre-drilling for excavation, services trenches and rock-fill foundation works.
Quarry production
Production hole drilling on quarry benches where a drill rig isn't economic.
Civil & infrastructure
Foundation drilling, anchor holes and ground reinforcement on construction sites.
