Versatile Drilling Across Materials
Engineered for precision and adaptability, these high-speed steel (HSS) pagoda drill bits are ideal for drilling into a wide range of materials. From sheet metals like aluminum, brass, and mild steel to plastics such as PVC and acrylic, they deliver clean, burr-free holes with minimal effort.
Controlled, Multi-Diameter Cutting
The pagoda (step) design enables gradual enlargement of holes without the need to switch bits. Each step is precisely machined for smooth transitions between diameters, allowing for controlled cutting and integrated deburring at every stage-resulting in clean, finished holes with reduced need for secondary work.
Heat-Treated for Extended Performance
Constructed from premium HSS and enhanced through advanced heat treatment, these bits are built to withstand the rigors of high-speed, high-temperature drilling. Their thermal stability ensures long-lasting sharpness and structural integrity, even when working with tougher metals.
Reliable Across Industries
Trusted by professionals and DIYers alike, these drill bits excel in electrical work, HVAC installation, metal fabrication, and plastic crafting. Whether modifying enclosures or creating precise panel cutouts, they offer unmatched efficiency and reliability in multi-purpose applications.
1. Razor-Sharp, Precision-Ground Cutting Edge
Crafted from high-speed steel (HSS), each bit features razor-sharp, precision-ground edges designed for efficient and controlled penetration into metal and plastic. These sharp cutting surfaces minimize resistance and reduce burr formation, producing clean, accurate holes with less effort.
2. Self-Centering Split Point Tip for Accurate Starts
The split-point tip is engineered to self-center on contact, eliminating the need for a center punch. This anti-slip feature ensures stable, walk-free drilling-even on curved or hardened metal surfaces-resulting in smoother, more controlled entry.
3. Step-by-Step Chip Evacuation for Smooth Operation
Each step is optimized for gradual cutting and effective chip removal. A spiral flute design enhances chip evacuation, minimizing heat buildup and reducing the chance of clogging. This promotes consistent drilling performance and extends the life of the tool during repetitive use.
4. Corrosion-Resistant Finish for Extended Durability
Protected by a polished or titanium-coated surface (where applicable), the bits resist wear and corrosion in harsh or moisture-prone environments. Ideal for professionals working with lubricants or in outdoor settings, the coating ensures lasting durability and reliability.
5. Multi-Stage, Balanced Cutting for Versatile Applications
The pagoda-style step geometry allows for multiple hole sizes with a single tool, reducing downtime from bit changes. Each step maintains optimal balance and control, making it especially effective for thin materials in electrical panels, automotive work, HVAC, and general fabrication.
Exceptional Wear Resistance & Thermal Stability
Crafted from premium high-speed steel (HSS), our pagoda drill bits are built to endure the intense heat and friction generated during metal and plastic drilling. Their superior hardness and thermal resistance maintain cutting sharpness and structural integrity, even when used repeatedly on demanding materials like stainless steel, aluminum, and PVC.
Precision Multi-Diameter Cutting with Clean Results
The pagoda-style step design allows for accurate, gradual hole enlargement across multiple sizes-without changing bits. Each step delivers a smooth transition with integrated deburring, resulting in clean, burr-free holes on both metal and plastic surfaces. This reduces the need for secondary finishing and streamlines your workflow.
Versatile, Professional-Grade Performance
Engineered for both professionals and advanced DIYers, this drill bit excels across a range of tasks-from electrical panel work and junction box drilling to plastic enclosure fabrication and HVAC installations. Its controlled, stable cutting action ensures reliable results with every use, making it an indispensable tool in workshops and job sites alike.
Advanced Steel Purification - EAF + LF + VD + RS ESR
Our bits are crafted from ultra-clean high-speed steel using cutting-edge metallurgical techniques: Electric Arc Furnace (EAF), Ladle Refining (LF), Vacuum Degassing (VD), and Electro-Slag Remelting (ESR). This reduces impurities, increases structural reliability, and ensures toughness needed for demanding applications like layered composites or hardened alloys.
Integrated Thermal Optimization for Structural Integrity
Each bit undergoes a precise sequence of quenching, cryogenic treatment, and tempering. This thermal cycle elevates hardness to HRC 67 while maintaining ductility-minimizing chipping and cracking during high-speed or high-pressure drilling in automotive, electrical, or fabrication environments.
RS ESR Edge Enhancement
Through Rapid Solidification ESR processing, the cutting edge is strengthened with evenly distributed carbides and cobalt content. This microstructure improves edge retention and wear resistance, ensuring high-performance cutting even under elevated thermal and mechanical loads.
Material Flexibility - M35-Centric Configuration
While M2 and M42 versions are available, our standard utilizes M35 high-speed steel for its balanced hardness and toughness. This makes it especially effective in drilling operations involving both metals and plastics where edge durability and longevity are critical.
Tailored Geometry and Coating Options
We offer customizable step dimensions, flute lengths, and helix angles to meet industry-specific needs. Additional PVD coatings-such as TiN, TiAlN, or TiCN-can be applied to boost thermal resistance, reduce friction, and extend operational life in harsh environments.
Multi-Step Flute Optimization
Each inter-step flute is engineered for smooth chip flow and thermal management. This prevents clogging and ensures consistent performance when drilling thermoplastics or thin metal sheets-especially under high RPM conditions.
Precision-Engineered Cutting Angles
Step transitions and tip geometry are carefully calibrated to lower axial force and increase stability. This reduces deformation in soft metals and prevents cracking in plastic components, delivering reliable, clean results.
Application-Specific Performance Coatings
Optional coatings like TiAlN and TiCN are available to enhance resistance to extreme temperatures and wear. These coatings are ideal for industrial applications requiring multi-diameter, continuous drilling through a range of materials.
Q1: What makes high-speed steel pagoda drill bits different from regular drill bits?
A: High-speed steel (HSS) pagoda drill bits are made from a specialized alloy known for its excellent heat resistance, edge retention, and durability. Unlike standard twist drill bits, pagoda bits feature a stepped design that allows for drilling multiple hole sizes with a single tool. The HSS construction ensures long-lasting performance, especially when drilling into tough materials like stainless steel, aluminum, and various plastics.
Q2: What materials can these pagoda drill bits handle?
A: These HSS step drill bits are engineered for precision drilling in both metal and plastic materials. They are ideal for use on sheet metals (aluminum, brass, mild steel, stainless steel) as well as plastic types such as PVC, ABS, and acrylic. Their clean cutting and integrated deburring make them perfect for electrical work, panel fabrication, and enclosure modification.
Q3: Are these pagoda drill bits available in different sizes or step configurations?
A: Yes, our pagoda drill bits come in a variety of step sizes and configurations to accommodate different hole diameters and material thicknesses. Whether you're drilling small openings in junction boxes or larger cutouts in control panels, we offer standard and customizable options to match your specific application requirements.
Q4: Can these drill bits be used for high-speed or continuous drilling operations?
A: Absolutely. Thanks to their HSS construction, advanced heat treatment, and optimized flute design, these bits are well-suited for high-speed and repetitive drilling. They resist heat buildup, maintain sharp edges, and provide smooth, controlled cutting-even under demanding conditions found in industrial, automotive, and electrical applications.
