Shibuya TS-255Pro Angle Base Core Drill

Description

Standard core rigs lack mast tilt capabilities, preventing technicians from drilling angled drain penetrations through thick concrete abutments. The Shibuya TS-255Pro Angle Base Core drill anchors securely to bore holes up to twelve inches in diameter at angles up to forty-five degrees. A multi-speed 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 angle base supported by heavy locking pivots and four leveling 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.

Angle Base Core Drill Specs

Tilting mast columns drill accurate angled holes up to 45 degrees for specialized mechanical drains. Precision rack-and-pinion feed handles permit smooth downforce control through tough concrete aggregate.

• 12-inch core bit capacity drills large mechanical penetrations through reinforced concrete slabs
• Two-speed motor gearbox selects 450 RPM or 950 RPM to match diamond core bit diameters
• 45-degree tilting angle base allows precise angled penetrations through foundation walls
• 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

Dynamometer Core Bench Telemetry

Bench testing quantifies electrical current draw and spindle torque across cured 5000 PSI reinforced concrete. The motor pulls 3.8 amperes unloaded, rising to 18.2 amperes while spinning an eight-inch diamond core bit through concrete and rebar. Spindle speed drops from 450 RPM down to 390 RPM under firm carriage downforce. Output torque stabilizes at 68 foot-pounds during continuous coring passes. Sound level meters read 87 dBA at operator ear level. Gearbox oil temperatures rise 30 degrees Fahrenheit after two deep slab cores.

Field Service Operational Traps

Loose pivot clamp bolts allow the mast angle to slip during drilling, binding the diamond core barrel. 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.

• Tighten mast angle adjustment bolts to specified torque before beginning angled drilling passes.
• 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.
