In the world of metalworking, stainless steel is notoriously difficult to machine. Its high toughness and work-hardening properties often lead to "bird-nesting"—where long, stringy chips clog the drill flutes, causing heat buildup and catastrophic tool failure. If your production line is struggling with these bottlenecks, Ningbo Lianchuang Hewo Precision Tools Co., Ltd has the precision-engineered solution you need.
The secret to high-speed drilling in gummy materials like M-group stainless steel lies not just in the hardness of the tool, but in the friction coefficient of the flute surface. Conventional drills often have microscopic ridges left over from the grinding process. These ridges act as friction points, causing chips to stick.
At Ningbo Lianchuang Hewo Precision Tools Co., Ltd, our Solid Carbide Twist Drills undergo a proprietary Fine Polishing process. By creating a mirror-like finish within the flutes, we drastically reduce friction. This allows chips to flow out smoothly and rapidly, boosting overall drilling efficiency by up to 30% while maintaining lower cutting temperatures.
Our tools are more than just bits of metal; they are high-performance instruments manufactured to the DIN 6537 standard. Key features include:
Optimized Geometry: Specifically designed for stable Centering Performance, preventing tool walking on hard surfaces.
Advanced Coating Technology: Complements the polished flutes to provide superior heat resistance and wear protection.
Material Versatility: While excelling in stainless steel (M), these Universal Drills are equally effective in Steel (P), Cast Iron (K), and Heat-Resistant Alloys (S).
Choosing Ningbo Lianchuang Hewo Precision Tools Co., Ltd means choosing a partner dedicated to your bottom line. Our High-Performance Drills are engineered to reduce cycle times and minimize scrap rates. When chip removal is no longer a hurdle, your CNC machines can run at their true potential.
Stop letting chip congestion slow down your factory. Upgrade to the polished excellence of Lianchuang Hewo tools and experience the difference in every hole.
