Husqvarna K 4000 Cut-n-Break – Electric Deep Cut Power Concrete Cutter for Indoor Contractors

16" Cutting Depth. Zero Emissions. No Corner Overcutting. Flush Cutting Capable.

K 4000 Cut-n-Break 9" – 967 08 33-01 | Twin Blades Included | 120V Corded Electric

The Husqvarna K 4000 Cut-n-Break is a professional corded electric power cutter engineered for contractors who need deep cutting depth with precise corner control in indoor and emission-sensitive environments. Using Husqvarna's patented Cut-n-Break method, the K 4000 cuts up to 16 inches deep from one side using twin 9" blades — with zero exhaust emissions, no corner overcutting, and lower diamond tool cost than conventional large-blade cutting. Its adjustable blade guard enables flush cutting close to walls and floors, making it the go-to tool for window openings, expansion joints, and precision indoor concrete work.

Wet and dry cutting capable. Twin blades included. No additional blades required to get started.

Built for Indoor Deep Concrete Cutting Without Emissions or Corner Overcutting

From window and door opening adjustments in occupied buildings to expansion joint cutting, groove work, and flush cuts against walls and floors, the K 4000 Cut-n-Break handles the precision indoor applications where gas-powered cutters are prohibited and overcutting corners is not acceptable. Its step-by-step Cut-n-Break method reduces diamond segment wear by cutting a controlled core rather than grinding through the full material width — lowering tool cost per cut and extending blade life on high-production indoor jobs.

Cut-n-Break Method – 16" Deep, Square Corners, Lower Diamond Cost

The Cut-n-Break system uses two 9" blades mounted in tandem to make parallel cuts that define a controlled core in the material. The core is then removed with the included breaking tool — leaving a clean, deep cut with square corners and no overcutting. This method reduces diamond segment contact area compared to a single large blade, significantly lowering wear and cost per linear foot of cut. The adjustable blade guard allows cutting flush to walls and floors — a critical advantage for opening work in finished spaces.

Elgard™ Overload Protection – Motor Protection on Every Cut

The Elgard™ electronic overload protection system continuously monitors motor load and automatically varies rotation speed to warn of approaching overload — protecting the motor from damage during hard cuts through reinforced concrete and extending machine service life. No manual intervention required; the system manages power delivery automatically so operators can focus on the cut.

Zero Emissions & Flush Cutting – The Indoor Concrete Cutting Advantage

Powered by a 2.4 hp corded electric motor at 120V, the K 4000 Cut-n-Break produces zero exhaust emissions during use — making it safe for occupied buildings, hospitals, schools, and any indoor environment where gas-powered equipment is restricted. The wet/dry cutting capability and adjustable water valve provide effective dust suppression for both indoor and outdoor applications.
