2. Multi-Diameter Drilling with Clean, Burr-Free Finishes
The precision-stepped design allows you to drill multiple hole sizes with a single bit, eliminating frequent tool changes and enhancing productivity. Each step delivers gradual, controlled hole expansion and produces smooth, burr-free edges-minimizing the need for secondary finishing and ensuring professional-grade results on sheet metal, plastic enclosures, and more.
3. Professional-Grade Versatility for a Range of Industries
Built for reliability, this heavy-duty pagoda drill bit is trusted by electricians, metal fabricators, HVAC technicians, automotive professionals, and advanced DIYers. Whether you're installing junction boxes, modifying vehicle panels, or cutting access holes in plastic housings, this bit delivers precision, control, and performance you can count on across a wide range of fabrication and installation tasks.
CNC Precision Grinding
Each Heavy Duty Pagoda Drill Bit is manufactured using advanced CNC grinding technology, ensuring razor-sharp cutting edges, uniform step heights, and true-centered tips. This precision reduces vibration and chatter during high-speed drilling, delivering accurate, clean hole formation across a wide range of diameters-ideal for professional work on automotive panels, enclosures, and structural sheet metals.
Vacuum Heat Treatment for Maximum Strength
To enhance wear resistance and structural integrity, each bit undergoes vacuum heat treatment. This process hardens the outer surface while preserving core toughness-ensuring long tool life, even under repetitive use in harsh environments such as stainless steel, aluminum bodywork, and industrial-grade plastics like PVC and ABS.
Ultra-Fine Polishing for Smoother Operation
A highly polished finish reduces surface friction and promotes efficient chip evacuation. This helps minimize heat buildup and prevents material melting or edge tearing-especially when drilling into soft plastics or thin-gauge metals-ensuring smoother, cleaner holes and prolonged tool lifespan.
Advanced Steel Purification (EAF + LF + VD + RS ESR)
Our pagoda bits are forged from high-speed steel refined through Electric Arc Furnace (EAF), Ladle Refining (LF), Vacuum Degassing (VD), and Electro-Slag Remelting (ESR). This ultra-clean steel structure eliminates impurities and improves toughness-critical for precision drilling through layered sheet metals and structural composites.
Integrated Thermal Optimization
Each drill bit undergoes a multi-stage thermal process-including quenching, cryogenic treatment, and precision tempering-achieving up to HRC 67 hardness. This balanced hardness-to-toughness ratio prevents edge chipping and cracking, even in high-speed, high-pressure fabrication or electrical installation environments.
RS ESR Edge Reinforcement Technology
Through Rapid Solidification ESR, carbide and cobalt particles are evenly distributed across the cutting edge, greatly enhancing edge retention and wear resistance. The result is a tool that withstands heavy thermal and mechanical stress-perfect for high-load, multi-pass drilling in metal fabrication, HVAC panels, and automotive applications.
M35-Centric Material Configuration
We prioritize M35 high-speed steel for its optimal hardness and durability balance. It's ideal for heavy-duty applications involving both metal and plastic, offering extended performance life and edge retention. M2 and M42 versions are also available for application-specific requirements.
Custom Step Geometry & Coating Options
Step count, flute length, helix angle, and shank type (round or hex) can all be tailored to fit professional workflow needs. For enhanced performance, optional PVD coatings-TiN (general wear), TiAlN (high temperature), or TiCN (abrasion resistance)-can be applied, further improving heat resistance and tool longevity.
Multi-Step Flute Design
Flutes between each step are engineered for smooth chip flow and heat dissipation. This prevents clogging and allows for consistent, high-speed performance-especially when drilling through thermoplastics, coated metals, or thin sheet materials.
Precision-Tuned Cutting Angles
Carefully calibrated step transitions and tip geometries reduce axial force and prevent distortion. This ensures stable, deformation-free hole creation-crucial for thin automotive panels, electrical boxes, and soft-metal structures.
Performance Coatings for Harsh Environments
Application-specific coatings such as TiAlN and TiCN increase thermal stability and edge life, enabling clean, multi-diameter hole drilling in fast-paced industrial settings.
