Corner-Cutter®

[:en]

For Dustless Cleanup of Concrete and Steel Surfaces

P/N: Z-001 (PDF version)

The Corner-Cutter® is designed to remove lead-based paints, radioactivity and other hazardous contaminants from both steel and concrete surfaces in an environmentally safe manner. Pentek developed the Corner-Cutter to scarify walls, joints, ceilings, stairs, girders, pipes, and other areas which are inaccessible to our MOOSE® and SQUIRREL®-III surface preparation products.

Corner-Cutter® operating principle is simple and effective.

The Corner-Cutter® operates on the same principle as a pneumatically operated needle scaler. Specially hardened needles operate within an evacuated stainless steel enclosure which prevents the escape of dust, debris and airborne contamination to the environment. Standard shrouds are provided with each unit to allow the cutters to conform to inside corners, outside corners, and flat surfaces. Special shrouds are available to conform to particularly odd geometric shapes, such as door and window frames. The Standard Shroud Set (P/N: X-009) includes 1 each of:

The Corner-Cutter® incorporates unique vacuum flow design features which provide high-efficiency performance in contaminated or clean room environments that require stringent control of loose material. Users will find that the Corner-Cutter® eliminates the need for the respiratory protection from radiological and toxic particulate hazards.  It also eliminated the need to erect tents or temporary protection enclosures.

The Corner-Cutter’s lightweight, low reaction forces and infinitely adjustable vacuum enclosure minimize operator fatigue and provide for comfortable operation in any position. The ergonomic design of the operator’s handle provides complete operator control and is equipped with a quick-release-to-off safety feature. A depth adjustment feature controls the cutting of cementitious surfaces.

Corner-Cutter® Applications

Surface Preparation

• Power Plants
• Water Tanks
• Public Housing
• Bridges & Tunnels
• Shipyards
• Industrial Plants
• Pulp & Paper Mills
• Food Processing Plants

Removes

• Radioactivity
• Lead Based Paint
• PCBs
• Concrete
• Rust & Corrosion
• Asbestos Gaskets
• Epoxy Coatings
• Chemical Spills

Specifications

Production Rate:

Flat surfaces: 20-30 square feet per hour (Nominal)
Edges and corners: 30-60 linear feet per hour (Nominal)

Cutting Width:

1-3/4 inches

Tool Length:

14 inches

Weight:

9 lbs.

Cutting Needles:

• 2mm diameter steel needles (flat top), best used to remove paint from steel and prepare the surface to SSPC specifications for the application of coating systems
• 3mm diameter steel needles (chisel point), best used to clean and prepare concrete for coating or new concrete application, and removal of thick marine and nuclear grade coatings
• 3mm diameter copper-beryllium needles (flat top), best used for reduced sparking applications in some explosive environments
• 4mm diameter steel needles (chisel point), best used to resurface brick and other fired materials

See Accessories & Spare Parts for part numbers.

Air Consumption

5 scfm @ 90 psig. Unit requires a 1/2-inch diameter air supply hose.

Vacuum Flow

To ensure adequate containment of dust/debris/contamination, the user must supply a minimum 50 scfm vacuum source at the 1 1/2-inch diameter vacuum hose connection. The unit will interface with Pentek-designed VAC-PAC® self-cleaning HEPA filtered vacuums or other high capacity, industrial quality vacuums.

Options

• Buffed and polished stainless steel surfaces.
• Vacuum hose with tool end cuff.
• Air supply hose.
• Quick-disconnect hose coupling at tool end.
• Custom shrouds for odd contours.
• Vibration-damped needle drivers.
• Hand Guard (replace P/N with A02001900)

Availability

Stock item; 3-4 weeks maximum delivery for special orders.

Limited Warranty

The Corner-Cutter® is warranted to be free of defects in material or workmanship for a period of 1 year from the date of delivery. Pentek makes no other warranties or representation, expressed or implied, with respect to functionality or fitness for use of a particular purpose. In no event shall Pentek be liable for any incidental or consequential damages arising out of the application or
use of any products provided.
