Description
Lightweight core rigs chatter across floors, snapping diamond segments and burning up motor armatures in cured concrete slabs. The Diamond Products M1AA-15 Complete Anchor Core Rig bolts down solidly to core holes up to ten inches in diameter. A heavy-duty electric drill motor drives precision gearing under mechanical carriage feed. Running diamond core bits dry without water flow melts matrix segments.
Precision-machined steel mast columns mount onto a cast aluminum anchor base supported by four leveling jack screws. The carriage rides along ground steel gear racks using adjustable brass shims that eliminate carriage chatter. The heavy drill motor wet-end features dual-insulated copper windings and internal slip clutches that decouple drive torque during core bit jams. Stainless steel water manifolds inject cooling water directly through the center spindle.
Anchor Core Rig Hardware Specs
Rigid steel mast assemblies eliminate drill bit chatter during deep structural slab penetrations. Precision rack-and-pinion feed handles permit smooth downforce control through tough concrete aggregate.
- 10-inch core bit capacity drills large mechanical penetrations through reinforced concrete slabs
- 15-ampere 115-volt motor delivers sustained drilling torque through hard river rock aggregate
- Precision-machined steel mast column prevents carriage deflection during deep coring runs
- Four leveling jack screws stabilize the cast base plate across uneven concrete surfaces
- Integrated water swivel injects cooling water through the spindle center to flush concrete slurry
- Mechanical slip clutch protects internal gears from shock damage during rebar contact
- Reversible carriage feed handle operates from left or right side for tight wall clearance
Dynamometer Core Bench Telemetry
Bench testing quantifies electrical current draw and spindle torque across cured 5000 PSI reinforced concrete. The motor pulls 3.6 amperes unloaded, rising to 14.8 amperes while spinning an eight-inch diamond core bit through concrete and rebar. Spindle speed drops from 800 RPM down to 680 RPM under firm carriage downforce. Output torque stabilizes at 54 foot-pounds during continuous coring passes. Sound level meters read 86 dBA at operator ear level. Gearbox oil temperatures rise 28 degrees Fahrenheit after two deep slab cores.
Field Service Operational Traps
Loose anchor bolts allow the mast base to shift, binding the diamond core barrel and stripping drive gears. Drywall contractors cutting plaster board have no use for this heavy core rig. Never operate this machine without securing the base with an anchor bolt.
- Flush the internal water manifold with clean water after finishing concrete coring jobs.
- Wipe abrasive concrete slurry off the steel mast column gear racks after every shift.
- Check carriage brass guide shims for loose play and adjust set screws monthly.
