Engineered for Tough Metal Drilling
This high-speed steel (HSS) pagoda drill bit is designed specifically for challenging materials like stainless steel, hardened alloys, and high-strength sheet metals. Whether you're working with aluminum, brass, or industrial-grade steels, it delivers clean, accurate holes with minimal burring and reduced tool wear.
Multi-Diameter Drilling with Built-In Deburring
Featuring a precision step design, this bit allows for drilling various hole sizes using a single tool-eliminating the need for frequent bit changes. Each step is machined for smooth transitions and includes a deburring edge that creates clean, finished holes without secondary processing.
Heat-Treated for Maximum Durability
Made from premium HSS and reinforced through vacuum heat treatment, this drill bit offers excellent thermal resistance and edge retention. It stays sharp and stable under the high-speed, high-temperature conditions typically encountered when drilling hard metals like stainless steel or carbon steel.
High-Performance Across Demanding Applications
Trusted by professionals in electrical work, automotive fabrication, HVAC installation, and industrial manufacturing, this bit excels in any job that requires clean, burr-free holes in durable metal surfaces. It's also highly effective on plastics such as PVC and ABS when precision and clean results are required.
1. Razor-Sharp Cutting Edge for Hard Metals
Crafted from industrial-grade high-speed steel (HSS), this drill bit features precision-ground cutting edges designed to pierce stainless steel and other hard metals with ease. The sharp edges reduce cutting resistance and minimize burr formation, enabling clean, smooth holes with less effort and longer tool life.
2. Self-Centering Split Point Tip for Accurate Starts
Equipped with a self-centering split point, the bit ensures stable, walk-free starts even on hardened or curved metal surfaces. No need for center punching-this feature delivers improved control and precision from the very first contact, which is critical when working with dense alloys.
3. Spiral Flute Design for Efficient Chip Evacuation
Each step includes a spiral flute optimized for rapid chip removal. This design minimizes heat buildup and prevents clogging during high-speed drilling, especially in hard metals where debris can slow progress and dull tools prematurely.
4. Corrosion-Resistant, Wear-Tough Coating
The bit is finished with a polished or optional titanium coating, providing added protection against rust and surface wear. This is especially important when drilling in industrial settings where lubricants, coolants, or high humidity are present.
5. Multi-Stage Step Design for Versatile Hole Sizes
The stepped geometry allows you to drill multiple hole diameters with a single eliminating frequent tool changes and improving workflow efficiency. Its balanced design ensures stable, vibration-free operation, making it ideal for applications such as control panel fabrication, steel enclosures, or automotive bodywork on hard metal surfaces.
1. Exceptional Wear Resistance & Heat Tolerance
Crafted from premium high-speed steel (HSS), this pagoda drill bit is engineered for the high friction and intense heat generated during drilling in stainless steel and other hard metals. Its advanced hardness and structural strength ensure long-lasting sharpness and resistance to edge wear-ideal for demanding, repetitive metalworking tasks.
2. Multi-Diameter Drilling with Clean, Burr-Free Results
With a stepped design optimized for metal drilling, this bit allows you to drill multiple hole sizes with one tool-saving time while maintaining accuracy. Each step delivers a smooth, controlled cut and clean hole edges, reducing or eliminating the need for post-drill deburring, even on tough materials.
3. Built for Heavy-Duty, Professional Use
Whether you're fabricating stainless steel panels, modifying industrial enclosures, or installing hardware in high-strength alloys, this bit provides precise control and consistent results. It's a trusted choice for metal fabricators, HVAC professionals, electricians, and advanced DIYers who need a reliable solution for drilling hard metals efficiently and cleanly.
Q1: What makes high-speed steel (HSS) pagoda drill bits ideal for stainless steel and hard metals?
A: Unlike standard drill bits, our HSS pagoda drill bits are engineered from premium alloy steel and undergo advanced heat treatment. This gives them superior wear resistance and thermal stability, allowing them to maintain sharpness and structural integrity even when drilling tough materials like stainless steel, hardened steel, and titanium. The titanium coating (if applied) further reduces friction and heat buildup.
Q2: What materials can these pagoda drill bits handle?
A: These step drill bits are specially designed for high-hardness applications, including stainless steel, carbon steel, aluminum alloys, brass, and even layered composite metals. They also perform excellently on rigid plastics like PVC and ABS, making them a versatile tool for electrical panels, control cabinets, and industrial fabrication.
Q3: Are these drill bits available in various specifications?
A: Yes, we offer multiple size combinations to accommodate a wide range of hole diameters. Each pagoda bit includes several step sizes in one tool, reducing the need for frequent tool changes. Custom designs-such as tailored flute lengths, step intervals, or hex/square shanks-can be provided upon request to match specific application requirements.
Q4: Can these bits be used for high-speed, continuous drilling?
A: Absolutely. These drill bits are optimized for high-RPM operations. The precision-ground cutting edges, spiral flutes, and thermal-resistant coatings work together to ensure efficient chip removal, prevent overheating, and deliver smooth, clean cuts-even during continuous drilling in hard metals.
