Description
Lightweight core drills struggle and overheat armatures when sinking large six-inch diamond barrels through thick foundation footers. The DEWALT POWERSHIFT 60V MAX* 6-3/8 Inch Core Drill Kit delivers relentless cordless torque for stand-mounted and handheld structural concrete coring. A 60-volt brushless motor drives precision gearing under mechanical carriage feed. Running diamond core bits dry without cooling water will melt matrix segments.
High-strength magnesium alloy gearboxes enclose a multi-speed gear transmission running on ground alloy steel shafts supported by tapered roller bearings. The electric motor wet-end features dual-bearing rotor supports and high-flux magnets that maintain steady torque under load. An integrated mechanical slip clutch decouples the drive train if rebar jams the diamond barrel. Stainless steel water feed spindles inject coolant directly through the core bit center.
Cordless Core Drill Hardware Specs
POWERSHIFT battery technology delivers massive industrial current without extension cords or fuel generators. Integrated water swivels inject coolant directly through the spindle to flush concrete slurry during coring.
- 6.375-inch core bit capacity drills large mechanical penetrations through reinforced concrete slabs
- Brushless 60-volt motor platform provides high drilling torque with low battery power drain
- Two-speed mechanical gearbox selects optimal RPM ranges to match diamond core bit diameters
- 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
- Anti-rotation system cuts motor power instantly during sudden bit bind-up to protect wrists
- Heavy steel anchor stand column prevents carriage deflection during deep foundation coring runs
Dynamometer Core Bench Telemetry
Bench testing quantifies electrical current draw and spindle torque across cured 5000 PSI reinforced concrete. The motor pulls 2.8 amperes unloaded, rising to 32.4 amperes while spinning a six-inch diamond core bit through concrete and rebar. Spindle speed drops from 800 RPM down to 690 RPM under firm carriage downforce. Output torque stabilizes at 46 foot-pounds during continuous coring passes. Sound level meters read 86 dBA at operator ear level. Gearbox oil temperatures rise 24 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. Plumbers installing residential copper pipe have no use for this heavy-duty core drill. Never operate this core drill without connecting a pressurized water feed line.
- Flush the internal water swivel with clean water after finishing concrete coring jobs.
- Check gearcase oil levels through the sight glass before starting weekly drilling shifts.
- Wipe abrasive concrete slurry off the anchor stand column tracks after every shift.
Commercial Warranty Package Inventory
DEWALT covers this cordless core drill kit with a 3-Year limited commercial warranty. The package contains the 60-volt core drill motor, anchor stand column, two 60-volt high-capacity batteries, fast charger, water connection hose, and heavy transport case.
