K4022-1 - Lincoln Electric Radius Spiral Handle Chipping Hammer

Industrial-Grade Slag Removal

The Lincoln Electric Radius Chipping Hammer (K4022-1) is a precision-engineered hand tool designed to meet the rigorous demands of professional welding environments. In processes such as Shielded Metal Arc Welding (SMAW) and Flux-Cored Arc Welding (FCAW), the efficient removal of slag is critical for inspecting weld quality and preparing for subsequent passes. This tool addresses the common challenges of manual slag removal through a robust design that prioritizes both durability and operator comfort.

Shock-Reducing Spiral Design

One of the defining features of the Radius line is the "bulletproof" spiral handle. Unlike solid steel or wood handles that transmit the full force of impact directly to the operator's wrist and forearm, the spiral wire construction acts as a mechanical dampener. This spring-like structure absorbs a significant portion of the shock generated when striking hardened slag, thereby reducing operator fatigue and the risk of repetitive strain injuries over long shifts. The open spiral design also aids in heat dissipation, keeping the handle cooler than solid counterparts when working near high-temperature weldments.

Versatile Head Configuration

The hammer head is forged from high-strength steel and features a dual-purpose configuration. One side presents a flat chisel edge, ideal for removing broad sections of slag and spatter from flat surfaces. The opposing side features a sharp spike or cone, designed to penetrate and dislodge slag from tight corners, root passes, and deep grooves. This versatility ensures that welders can clean complex joint geometries without needing to switch tools.

Practicality and Durability

Measuring 11 inches in length, the K4022-1 offers excellent leverage while remaining compact enough for confined spaces. The steel construction ensures long service life even in abusive industrial settings like shipyards, pipelines, and heavy fabrication shops. An integrated hook formed into the end of the spiral handle provides a simple yet essential solution for tool storage, allowing the hammer to be hung on pegboards, welding carts, or belt loops when not in use.
