Product details

Insoul chisels are meticulously engineered for tradesmen who refuse to compromise on precision. Forged from high-carbon steel graded at C1045 and C1050, the blades undergo a rigorous heat-treatment process to achieve a consistent Rockwell hardness of 58 to 60 HRC. This hardness level ensures the cutting edge withstands high-impact use without deformation or rolling. The cutting geometry features a precision-ground bevel angle calibrated between 25° and 30°, optimized for clean engagement with wood, masonry, or metal. To guarantee uniform cuts and flat recesses, each blade maintains a strict straightness tolerance of ≤0.1mm runout across its entire 150-250mm length, delivering professional-grade results with every strike.

Electric Hammer Chisel Performance Specifications

Blade material: High-quality alloy steel (40Cr grade) with HRC 60-62 hardness rating, specially forged for electric hammer compatibility, ensuring excellent edge retention and resistance to dulling under high-frequency impact.

Precision-ground cutting edge with a 30°-35° bevel angle, optimized for electric hammer’s impact force transmission, enabling effortless penetration into concrete, brick, stone, and reinforced mortar without edge chipping.

Edge sharpness retention: Maintains stable cutting efficiency for up to 80+ hours of continuous use on C20-C30 concrete, resisting wear caused by high-frequency vibration and hard aggregate impact, reducing re-sharpening frequency.

1.Blade Hardness & Sharpness (Electric Hammer Adaptation)

High-frequency impact resistance: Withstands continuous electric hammer impact (up to 3000 BPM, 250N impact force) without blade bending, deformation or chipping, thanks to integral quenching and tempering treatment of the blade core.

Material removal rate: Cooperates with electric hammer’s impact mechanism, removing up to 2.5cm³ of C25 concrete per impact cycle, 1.8cm³ of brick per cycle, significantly improving construction efficiency for wall chiseling, groove opening and demolition work.

Straightness tolerance: Blade runout ≤0.08mm over the entire length (200-350mm), ensuring uniform force transmission with electric hammer, avoiding deviation during groove opening and chiseling, and ensuring construction precision.

2.Impact Resistance & Power Transmission (Electric Hammer Matching)

Blade coating: Titanium nitride (TiN) coating with high hardness and wear resistance, salt spray test resistance of 72+ hours, effectively preventing rust and corrosion in humid construction environments and extending service life.

Shank connection: Standard SDS plus/SDS max shank (compatible with most electric hammer models), with precision machining and anti-slip grooves, achieving a pull-out force of ≥300N, avoiding shank slipping during high-frequency impact.

Blade toughness: The blade adopts a multi-layer forging process, with impact toughness ≥12J, resisting cracks and breakage from accidental collisions and uneven force during electric hammer operation, adapting to heavy-duty construction scenarios.

3.Durability & Corrosion Resistance (Heavy-Duty Operation)

Weight balance: Optimized shank and blade weight distribution, matching electric hammer’s center of gravity, reducing arm fatigue during long-term holding and operation, and improving operation stability.

Installation design: Quick-release shank design, enabling one-hand installation and disassembly with electric hammer, no additional tools required, saving time for construction switching.

Vibration reduction coordination: The shank is equipped with a shock-absorbing gasket, reducing the transmission of electric hammer vibration to the hand by 40% compared to ordinary electric hammer chisels, minimizing operator fatigue during long-term (6+ hours) continuous operation.

4.Ergonomics & Installation Convenience

Insoul chisels are engineered to perform reliably across a wide operating temperature range of -20°C to 80°C. Whether used in freezing outdoor construction sites or high-temperature continuous operation environments, the material maintains stable hardness and impact resistance without becoming brittle or suffering performance degradation. This thermal stability ensures that tradesmen can rely on consistent cutting and chipping action regardless of weather conditions or prolonged tool use, making these chisels a versatile choice for year-round professional applications.
