The Little Tungsten Factory That Turned a Supply Crisis Into Its Best Quarter Ever

Most metals are shaped by melting them and pouring them into a mould. Tungsten does not cooperate that way. Its melting point is around 3,422 degrees Celsius, so the industry works with it as a powder instead.

That powder gets mixed with a softer metal, compressed, and heated just enough for the softer metal to flow around the hard grains. The result is a material that can cut steel, drill rock, and survive repeated impact. For decades, one country dominated the global supply of the raw materials behind that process.

A 1970s factory that bet on the hard stuff

Rapicut Carbides Limited entered this world in the late 1970s. It was incorporated as a public company in April 1977, and production began in October 1979 at a plant in the GIDC estate in Ankleshwar, Gujarat. From the start, the company tried to do something rare: run the entire tungsten carbide value chain, from chemical intermediates to finished inserts and tools.

The metallurgy behind the miracle

The core skill is powder metallurgy. Tungsten carbide starts as a fine powder, combined with carbon and then carburized. Because pure tungsten carbide is extremely hard but brittle, a softer metal—usually cobalt—is added as a binder. That mix is milled wet for anything from 24 to 48 hours until the particles are an ultrafine 0.5 to 2.0 micrometers across.

Next comes pressing, with compaction pressures between 200 and 400 MPa. That creates a 'green' compact at roughly 50% to 60% of its final density. Then the compact goes into a controlled-atmosphere or vacuum furnace.

• Debinding and presintering at 400°C to 800°C, over one to two hours
• Solid-phase sintering at 800°C to 1,300°C
• Liquid-phase sintering at 1,400°C to 1,600°C, when the cobalt binder melts and fills the pores

For parts that will face high impact, manufacturers go further with Sinter-HIP. That step uses argon gas pressure during cooling to push the material toward near 100% theoretical density. Internal voids are not welcome in a mining bit or an aerospace component.

The ratio of tungsten carbide to cobalt, plus grain size, decides how a grade behaves. International standards group the grades into ISO series: K for cast iron, M for stainless and difficult-to-machine alloys, and P for steel. Rapicut formulates to ISO, British, Swedish, and German specifications.

What the factory actually sells

The product range is broad. In mining, Rapicut makes drill steel inserts brazed onto drill rods, tungsten carbide buttons for percussive and down-the-hole drilling, and heavy inserts for bucket wheel excavators used in open-cast lignite and brown coal mining. The active catalogue runs to more than 2,000 standard and custom varieties.

In precision machining, Rapicut supplies brazed tips, indexable milling inserts, and solid carbide cutters for automotive and heavy machinery. Its wear-parts division makes ladle cleaning inserts, shear blades, hole punching dies, mechanical seal rings, V-notch dies, squeeze rolls, and oil and gas flow control parts. For tube manufacturers, it supplies solid plugs, semi-floating plugs, and scarf tools.

But the shift most relevant to the turnaround sits in intermediates and metallurgical powders. Rapicut sells tungsten metal powder, tungsten carbide powder, ammonium paratungstate, tungsten trioxide powder, cobalt oxide, and cobalt metal powder. Commercial intermediates are often priced between ₹2,500 and ₹6,500 per kilogram depending on the compound and purity. That upstream business lets the company spread revenue across raw-material demand as well as finished tools.

The uncomfortable geography of tungsten

Tungsten is not just another industrial raw material. It is a strategic mineral with no easy substitute in aerospace, defence, advanced electronics, and heavy manufacturing. Global supply is overwhelmingly dominated by China, which controls most primary mining output and most midstream processing, including the conversion of ore into ammonium paratungstate, or APT.

In recent years, China has tightened export restrictions and quotas on tungsten products, including powders and carbide materials, citing national security and industrial priorities. Exporters must now secure government permits before shipping minerals overseas. One immediate effect was a cost shock: APT surged by over 20% in a compressed timeframe, and manufacturers scrambled for supply.

India has officially classified tungsten and cobalt among the 30 minerals considered critical to national security, defence manufacturing, and the clean energy transition. But primary mining is virtually absent, historically limited to marginal output from sites like Degana in Rajasthan. So the more practical path is reclaiming tungsten from old tools, worn drilling bits, and industrial scrap.

Rapicut has focused on exactly that. Using chemical or zinc-melt processes, it separates tungsten carbide grains from the cobalt binder in end-of-life tools and scrap. That creates a domestic secondary source of supply, and it changes the company's exposure to China.

A supply chain vulnerability became a competitive moat: the same export restrictions that once threatened Rapicut's margins are now the reason its order book is full.

From losses to a record quarter

For years before this shift, the financials were not good. Revenue moved from ₹28.01 crore in FY21 to ₹60.16 crore in FY24, then fell back to ₹41.99 crore in FY25. The company reported total revenue of ₹42.13 crore in FY25 and a net loss of ₹2.33 crore. Management cited raw material price volatility and global restrictions on rare earth metals as key catalysts. EBITDA margin for FY25 was negative, at -2.49%, while total expenses of ₹44.38 crore outpaced revenue.

Then FY26 changed the picture. Revenue from operations jumped 129% year-on-year to ₹96.28 crore. Net profit came in at ₹2.06 crore, reversing the prior year's loss. The driver was exports: export revenue surged from ₹18.15 lakh in FY25 to ₹46.21 crore in FY26. International buyers, cut off from Chinese supply lines, turned to companies that could still ship tungsten intermediates.

Cost of materials consumed rose too, to ₹100.49 crore. The ability to remain profitable despite that cost inflation points to pricing power: international clients ultimately paid for supply security.

One quarter that rewrote the comparison

Q1 FY27, which ended June 30, 2026, turned the accelerator into something closer to a launch. Revenue from operations for the single quarter was ₹82.04 crore, up from ₹10.37 crore in the corresponding quarter a year earlier—a jump described as 690% to 800%. Net profit hit ₹8.16 crore, against a net loss of ₹1.41 crore in Q1 FY26. That one quarter produced more profit than all of FY26.

There is an accounting nuance worth noticing. The cost of materials consumed, at ₹87.70 crore, exceeded revenue for the quarter. But a favourable change in finished goods, work-in-progress, and stock-in-trade provided a positive adjustment of ₹20.10 crore. The company was essentially running at full capacity, converting expensive raw material into finished inventory against a large order book. Net profit margin for the quarter was 9.96%.

A zero-debt company stocking up

By the end of FY26, Rapicut had repaid its cash credit facilities and reported debt-to-equity of zero. Total assets doubled from ₹31.78 crore in FY25 to ₹65.53 crore in FY26. A large share of that growth was inventory, which rose to ₹38.71 crore. In a normal manufacturer, that might scream weak demand. Here, with tungsten prices rising and export quotas spreading, it reads more like pre-emptive stockpiling.

Operating cash flow turned positive at ₹11.77 crore in FY26, versus a ₹3.90 crore outflow the prior year. Cash and equivalents closed at ₹3.00 crore, up from just ₹1.63 lakh a year earlier. Then, at the 49th Annual General Meeting scheduled for September 26, 2026, the board sought permission to raise aggregate borrowing limits to ₹100 crore to fund expansion and working capital.

Who is steering the factory

The company is run by Chairman and Managing Director Abhishek Vipinchandra Gami. The board includes Non-Executive Director Shruti Abhishek Gami and independent directors Kishore Dindayal Sharma, Atul Ravindra Garg, and Nrupang Bhumitra Dholakia. A new CFO, Pratham Pandya, was appointed effective August 10, 2026, following the resignation of P.R. Venkatta Ramanan. Kamlesh M. Shinde is company secretary and compliance officer.

Auditors are changing too. M/s S M R P & Associates have been proposed for a five-year term, replacing M/s K C Mehta & Co. LLP. The new audit fee is ₹5.00 lakh per annum, slightly lower than the ₹6.00 lakh previously paid.

Shareholding is mostly promoters and public investors. Promoter holdings rose to 41.72% in June 2026 from 40.46% a year earlier. Promoter pledge is 0.00%. Institutions barely feature: DIIs hold 0.19% and FIIs, mutual funds, and other institutional investors hold 0.00%. That is a microcap dynamic, but it also means the turnaround is not yet widely owned by large institutional money.

What the market is now paying

Rapicut Carbides is listed exclusively on the BSE under scrip code 500360 (ISIN INE350D01015). The stock has made a multibagger move. As of mid-September 2026, the equity traded in a range of ₹340 to ₹66.66. That works out to a 1-year return in excess of 280% to 291%, and a 5-year return exceeding 936%.

On valuation measures, the stock trades at a trailing P/E of 15.78 to 16.15 and a price-to-book of 6.29 to 8.48. Return on equity is 9.49% to 9.98% on a trailing basis, with ROCE at 11.3% to 12.5%. Those multiples are below the broader industrial machinery sector median, which often exceeds 55x. That suggests the market is not yet pricing a smooth continuation of Q1 FY27 earnings.

Peer context includes Kennametal India Ltd. and Sandvik Asia, plus domestic peers such as Jasch Gauging Technologies and KPT Industries. Rapicut's edge is agility: custom form tools, quick supply of intermediate powders, and import-substitution products where larger players may not compete on short lead times.

The next test

The risk is that commodity cycles do not stay friendly forever. If global demand slows, or new non-China tungsten projects come online quickly, the premium prices on intermediate products could compress. The large inventory position at ₹38.71 crore is a hedge against rising input costs, but it also creates write-down risk if tungsten prices suddenly fall.

The upside is equally specific. The board's ₹100 crore borrowing-limit plan signals management expects durable expansion, not a one-quarter spike. If capital goes into press machines, grinding equipment, and additional Sinter-HIP capacity—especially for aerospace and defence work—the company could raise baseline output and reduce its reliance on cyclical mining tools. Deeper recycling capability would also lock in a domestic supply source while China restricts exports.

Why this moment matters

This is not a story about a stock tip. It is a story about how an old-line Indian factory used metallurgical skill and a zero-debt balance sheet to step into a global supply gap. The company emerged from losses by selling high-value tungsten intermediates and finished products to buyers who no longer had the luxury of waiting for Chinese shipments.

Whether Rapicut can turn an extraordinary export quarter into a durable baseline is the real question. The inventory, the borrowing-limit expansion, and the recycling push all point the same way: management is betting that the world's tungsten problem will not resolve overnight.
