Domestic tungsten steel drill bits achieve a significant breakthrough
Recently, a company in the Torch High-tech Zone
Xiamen Maida Intelligent Technology Co., Ltd.
announced
the successful production of
tungsten steel drill bits with a diameter of only 0.009mm (9 microns)
which can be applied in the fields of semiconductors,
medical devices (such as micro-hole processing for cardiac stents),
and other high-end manufacturing sectors
This also means
that our country has achieved technological autonomy and control
in the “micro battlefield” of ultra-micro drill bits below 0.01mm

“Although the drill bit is small, it is the ‘tooth’ of industrial manufacturing.” Liu Guangda, chairman of Maida Intelligent, explained that high-end manufacturing such as semiconductors is like building skyscrapers on a “hair strand,” requiring extremely high precision for drill bits—not only must they drill accurately, but the error must also be controlled at the micron level.
For a long time,
0.01mm has been regarded as the “limit size” for domestic tungsten steel drill bits.
There are very few companies globally that can stably mass-produce smaller specifications.
“Only a handful”
0.009mm
is roughly one-tenth the diameter of a common hair strand.
From 0.01mm to 0.009mm
may seem like a mere 0.001mm leap,
but it is actually a technological “gap”
that must achieve collaborative breakthroughs in material formulation, processing technology,
and quality control.
“The R&D team innovatively adopted a ‘counterintuitive’ material ratio, enhancing toughness while increasing hardness.” Liu Guangda explained, “The smaller the size, the more pronounced the contradiction between hardness and toughness; too hard can lead to cracking, while too tough can cause deviation during drilling. After multiple formulation experiments, we finally found the best balance point.”
In the processing phase, the R&D team implemented micron-level breakthroughs, not only advancing the drill bit diameter to 0.009mm but also controlling the edge sharpness error within 0.3 microns, achieving performance indicators at the international advanced level.
Successful R&D is just the first step; high yield and stable mass production are key.To this end, Maida Intelligent has established a full-process monitoring system from materials to finished products, marking each drill bit with micron-level laser markings to achieve quality traceability throughout its lifecycle.
A micro drill measures the precision of Chinese manufacturing and witnesses the firm steps of Xiamen technology companies moving towards “new” and “high” advancements. As a national high-tech enterprise, Maida Intelligent has been deeply engaged in the precision tool manufacturing field for many years, focusing on high-end links in the industrial and value chains, accelerating the transformation towards semiconductor processing tools. Previously, the company has successively broken through key sizes of 0.015mm and 0.01mm.
“Achieving ‘millimeter precision’ relies on unwavering focus and dedication to the core business.” Liu Guangda stated that the company has not only achieved self-reliance in core technologies but has also gained recognition in the international market, with products exported to countries such as Japan and South Korea, “In some key indicators, such as continuous drilling life, our products have surpassed international brands.”
