Rebar Thread Cutting Machine

Engineered for high-throughput production in demanding fabrication environments, the Rebar Thread Cutting Machine by National Cutting Tools is built for <p>The Rebar Thread Cutting Machine is a specialized site and workshop machine engineered for cutting parallel metric threads onto the ends of reinforcing steel bars (TMT bars) used in mechanical rebar splicing. In modern high-rise buildings, bridges, and infrastructure projects, traditional lap splicing wastes valuable steel, causes steel congestion in concrete pour zones, and fails under seismic shear loads; mechanical couplers with parallel-threaded rebar ends provide full 100% bar-break tensile connections conforming to IS 16172 and ACI 318.</p>.

<p>Equipped with an automatic rebar clamping vise, an electric-powered hollow spindle, and adjustable tangential or radial chaser heads, the machine cuts clean, uniform threads on rebar diameters from 16 mm up to 40 mm (Fe 500, Fe 550, and Fe 600 grades). The threading cycle takes only 30 to 45 seconds per bar end, producing sharp thread profiles that thread effortlessly into standard rebar couplers on the construction site.</p>

<h3>Key Features</h3>

<ul>

<li><strong>High-Tensile TMT Threading:</strong> Specially tempered chasers easily machine through the hard martensitic outer layer of Fe 500D and Fe 550D TMT rebar without chipping.</li>

<li><strong>Parallel Metric Thread Profile:</strong> Cuts straight M16 to M40 threads with consistent pitch for seamless mechanical coupler engagement.</li>

<li><strong>Heavy-Duty Rebar Clamping Vise:</strong> Hardened serrated clamp jaws bite into rebar ribs firmly, preventing any bar rotation under heavy cutting torque.</li>

<li><strong>Micro-Adjustable Length Stop:</strong> Ensures exact thread length matching coupler barrel depth, eliminating exposed incomplete threads.</li>

<li><strong>Rigid Mobile or Shop Frame:</strong> Compact structural footprint allows mounting on a shop floor or placing directly on large infrastructure project job sites.</li>

<li><strong>High-Efficiency Coolant Circulation:</strong> Keeps cutting chasers cool during continuous rebar production, maximizing tool life per regrind.</li>

</ul>

<h3>Applications</h3>

<ul>

<li>Infrastructure projects: metro rail viaducts, bridge piers, and flyover pillars</li>

<li>High-rise commercial and residential reinforced concrete construction</li>

<li>Rebar processing yards and cut-and-bend steel service centers</li>

<li>Nuclear power plant and heavy civil engineering foundation rebar splicing</li>

</ul>

<p>Manufactured at National Cutting Tools in Ludhiana. Every machine is tested on high-tensile TMT rebar samples with thread go/no-go gauges and tensile coupler pull-out verification prior to dispatch.</p>
