Specifically engineered for automotive sheet fabrication, these high-precision HSS pagoda drill bits deliver consistently clean, burr-free holes in a variety of materials. Ideal for aluminum panels, mild steel sheets, plastic housings, and composite body components, each bit allows multi-diameter drilling with precise control-perfect for applications demanding professional-grade finish and fit.
Each step on the pagoda drill bit is CNC-ground for exact sizing and smooth step transitions. The integrated deburring design creates clean hole edges at every diameter, eliminating the need for secondary finishing. This significantly streamlines workflow in auto body shops, custom fabrication, and component fitting tasks.
Crafted from heat-treated high-speed steel, these drill bits deliver superior hardness and structural reliability under high-speed, high-friction conditions common in automotive environments. Their exceptional thermal stability ensures lasting sharpness and minimal wear, even when drilling coated or multi-layered vehicle panels.
Whether you're modifying dashboards, installing sensors, cutting access ports, or mounting brackets, this pagoda drill bit delivers precise, repeatable results across automotive sheet metals and plastics. Its ability to produce clean holes without deformation makes it an essential tool for technicians, custom builders, and high-precision fabricators.
1. Precision-Ground Cutting Edge for Clean Entry
Crafted from premium high-speed steel (HSS), each pagoda drill bit features ultra-sharp, CNC-ground cutting edges designed for effortless penetration through automotive-grade sheet metals and plastics. This precision ensures minimal burring and creates clean, accurate holes-critical for panel fittings, bracket mounts, and cable pass-throughs.
2. Self-Centering Split Point for Accurate Start
The split-point tip delivers instant self-centering without the need for pilot holes, minimizing bit walking on curved or painted metal surfaces. This ensures precise hole placement during vehicle panel drilling, interior modification, and electrical component installation.
3. Optimized Flute Design for Smooth Chip Ejection
The high-efficiency spiral flutes are optimized for clean chip evacuation during step transitions. This reduces heat buildup and prevents clogging-maintaining a smooth cutting path through thin-gauge steel, aluminum skins, and plastic automotive trim materials.
4. Protective Anti-Corrosion Coating for Longevity
Each bit is coated with a durable anti-corrosion finish such as titanium nitride (TiN), which enhances surface hardness and resists wear. This extends tool life in demanding auto body environments-especially where moisture, heat, or abrasive materials are present.
5. Balanced Multi-Diameter Cutting in One Tool
With a precisely engineered stepped design, this pagoda drill bit allows technicians to drill multiple hole sizes with a single tool-eliminating the need for bit changes. It's ideal for automotive tasks requiring accurate, repeatable holes for wiring grommets, sensor ports, mounting hardware, and ventilation cutouts.
1. Precision Engineering for Clean, Accurate Hole Making
Designed for automotive-grade sheet metal, our pagoda drill bit delivers clean, concentric holes with minimal burring. CNC-machined step geometry ensures tight tolerances, reducing chatter and deformation-ideal for tasks like panel mounting, bracket installation, and component fitting in vehicle fabrication.
2. Superior Wear Resistance and Thermal Control
Manufactured from high-grade heat-treated HSS, this bit resists edge wear and distortion even under continuous high-speed use. Whether you're drilling aluminum body panels, mild steel enclosures, or plastic interior trims, it maintains sharpness and temperature control to prevent damage to both tool and workpiece.
3. Multi-Diameter Drilling Without Sacrificing Accuracy
Each step is precisely defined to allow progressive hole enlargement without compromising alignment or surface integrity. This eliminates the need for tool changes and ensures consistent hole sizing-perfect for electrical ports, sensor holes, or grommet cutouts on automotive assemblies.
4. Built for Automotive Precision Tasks
From dashboard mods and under-hood wiring to custom bodywork and trim retrofits, this pagoda drill bit delivers flawless results in applications where precision is non-negotiable. It ensures tight fits for fasteners, cable entries, and integrated components across automotive sheet and plastic materials.
5. Maximum Efficiency, Minimal Effort
Combining clean hole quality, multi-size functionality, and excellent control, this tool streamlines drilling operations in auto shops and fabrication bays. Whether you're a professional technician or a custom car builder, it delivers fast, repeatable results-reducing labor time and improving finish quality.
1. CNC Precision Grinding for Perfect Hole Geometry
Each pagoda drill bit is CNC-ground to exact specifications, delivering concentric step geometry and uniform step heights. The razor-sharp cutting edges and centered split-point tip ensure accurate, burr-free holes in automotive sheet metal, plastic trim panels, and enclosures-ideal for fastener ports, wiring access, and bracket mounting.
2. Vacuum Heat Treatment for Strength Under Load
To withstand the demands of automotive fabrication, each bit is vacuum heat-treated to optimize core toughness and surface hardness. This treatment allows for sustained performance in stainless steel, aluminum body panels, ABS interior plastics, and other vehicle materials under high-speed, repetitive use.
3. Ultra-Fine Polishing for Smooth Operation
The mirror-polished finish significantly reduces friction and heat buildup-crucial for preventing surface distortion and melting when drilling through thermoplastics or coated metal panels. Improved chip evacuation ensures faster hole formation and cleaner cutting paths.
1. Ultra-Pure Steel Production: EAF + LF + VD + RS ESR
Our bits are forged from premium high-speed steel using a multi-stage purification process-including Electric Arc Furnace (EAF), Ladle Refining (LF), Vacuum Degassing (VD), and Electro-Slag Remelting (ESR). The result: reduced impurities, increased structural consistency, and superior performance in multi-layered automotive sheet assemblies.
2. Full-Spectrum Thermal Optimization
The bits are treated through quenching, cryogenic hardening, and precision tempering to achieve up to HRC 67 hardness while maintaining crack resistance. This thermal profile ensures edge durability and longevity under high-speed, high-pressure drilling tasks common in auto body and custom fabrication.
3. RS ESR Edge Reinforcement
Using Rapid Solidification ESR technology, cutting edges are strengthened by the even distribution of fine carbides and cobalt. This extends wear life and ensures sharpness is retained when drilling high-strength steel, aluminum skins, or composite structures in automotive panels.
1. Material Options for Specialized Use
Our default choice-M35 high-speed steel-delivers the ideal combination of edge strength and toughness for automotive-grade materials. M2 and M42 variants are also available to suit specific fabrication demands or budget constraints.
2. Geometry & Coating Flexibility
Tailor your bit for the job: choose step counts, flute lengths, helix angles, and shank styles (round or hex). Optional PVD coatings like TiN, TiAlN, and TiCN provide enhanced heat resistance and durability-essential for long runs in high-speed drill presses or hand drills used in vehicle assembly and retrofitting.
Multi-Step Flute Geometry: Engineered to rapidly clear chips and manage heat-crucial when drilling coated or thin-gauge automotive sheet metal.
Tuned Cutting Angles: Lower axial force reduces panel distortion and ensures a clean finish on thin, curved, or soft automotive surfaces.
High-Performance Coatings: Application-specific coatings extend tool life while maintaining clean, accurate hole edges in fast-paced fabrication lines or repair settings.
