    🛡 Enhanced Safety & Control Features for Demanding Work

    This grinder integrates advanced safety and user-control systems. The soft start feature reduces initial torque reaction for smoother, more controlled startup. Anti-restart protection prevents the tool from accidentally turning on if power is restored after an interruption. A removable anti-slip auxiliary handle offers multiple mounting positions for optimal two-handed control during heavy cutting or grinding. The included protective cover is essential for deflecting sparks and debris, safeguarding both the operator and the tool's internal components.

    Frequently Asked Questions
    Q What type of motor does the KAG71801 use, and why does it matter?
    The KAG71801 uses a 4835 all-copper brushless motor. Unlike brushed motors or copper-clad aluminum alternatives, a brushless all-copper motor delivers superior torque, greater energy efficiency, significantly less heat buildup, and a much longer operational lifespan — making it ideal for sustained professional use.
    Q What safety features are built into this angle grinder?
    The KAG71801 includes two critical safety systems: a soft start feature that gradually ramps up motor speed to reduce sudden torque reaction at startup, and anti-restart protection that prevents the grinder from unexpectedly restarting if power is interrupted and then restored. Together, these features help protect both the operator and the workpiece.
    Q What battery sizes are compatible with the KAG71801?
    The KAG71801 operates on a 20V DC battery platform and is compatible with 2.0Ah, 3.0Ah, and 4.0Ah lithium-ion battery packs. All compatible packs include standard electrical protections. This flexibility allows users to balance runtime requirements against tool weight depending on the job at hand.
    Q What tasks can the KAG71801 angle grinder handle?
    This grinder is designed as a multi-purpose professional tool for metalwork applications. It is capable of metal cutting (pipes, rebar, conduit, sheet metal), metal grinding (weld seams, rust removal, edge smoothing), and surface preparation using sanding or flap discs. Its 115mm wheel capacity and 8,500 RPM speed make it well-suited for demanding job site tasks.
    Q What accessories are included in the KAG71801 kit?
    The KAG71801 comes as a complete ready-to-work kit including: the angle grinder unit, abrasive discs, a spanner, a removable anti-slip auxiliary handle, a protective cover, a lithium-ion battery, and a charger. No additional purchases are required to begin work immediately upon delivery.
