Husqvarna K 40 Pneumatic Power Concrete Cutter – Air-Powered Cutting for Confined & Indoor Job Sites

No Electricity. No Emissions. Powerful Cutting Anywhere Compressed Air Reaches.

K 40 Pneumatic Power Cutter - 968 37 24-01

The Husqvarna K 40 is a professional-grade pneumatic power cutter built for contractors who work in environments where electric and gas-powered cutters can't go. Powered entirely by compressed air, the K 40 delivers 4.3 hp (3.2 kW), 5 inches of cutting depth, and a 14-inch blade capacity — with zero emissions, no electrical hazard, and no fuel to manage.

Its long, slim body with excellent lateral balance and ergonomic handle design makes it the right tool for pipeline trenches, deep foundation sites, marine docks, and any low air-change-rate environment where gas or electric cutters are impractical or prohibited. Diamond blade not included.

Built for Confined Spaces, Trenches & Low Air-Change Environments

From cutting cast concrete and curbstones in pipeline trenches to floor and wall cutting in enclosed indoor spaces, the K 40 handles the applications that gas and electric cutters can't. No exhaust fumes in confined spaces. No electrical hazard near water or in wet environments. No generator required on remote sites. Just connect to a compressed air supply and cut.

Pneumatic Motor – Zero Emissions, Intrinsically Safe Operation

The K 40's air-powered pneumatic motor produces zero combustion emissions during use — making it the only safe choice for cutting in pipeline trenches, underground vaults, marine environments, and other confined spaces where exhaust fumes or electrical sparks are a hazard. An oil mist lubrication system keeps the motor running smoothly with minimal maintenance.

Smooth Blade Stop – Faster Job-to-Job Transitions

The smooth blade stop system reduces blade deceleration time when the machine is switched off — so operators can safely move to the next cut faster without waiting for the blade to coast to a stop. On high-production confined-space jobs, this translates directly to more cuts per shift.

Ergonomic Design – Low Fatigue in Tight Spaces

The K 40's slim, well-balanced body with good lateral weight distribution and an ergonomic handle reduces operator strain in the awkward positions common to trench and confined-space work. At 21.8 lbs, it's manageable in tight quarters where heavier gas cutters become a liability.
