Product Introduction
For metal fabrication, steel structure construction, industrial machining and professional DIY projects, an annular cutter (hollow drill bit) is the go-to tool for fast, precise, and burr-free hole drilling in steel plate, stainless steel, alloy steel, iron plate and other ferrous/non-ferrous metals. However, the performance of an annular cutter is only as good as its connection to your power tool. Our annular cutter adapters (also known as hollow drill bit adapters, drill chuck adapters) are precision-engineered to solve this critical link, delivering secure, high-torque, and reliable connections between annular cutters and all mainstream power tools, maximizing drilling efficiency, extending tool life, and ensuring operational safety.
Manufactured from high-strength carbon steel with a hardened surface (HRC 45-50), our annular cutter adapters are built to withstand the extreme torque and impact of heavy-duty metal drilling. With universal compatibility, professional-grade clamping design, and tool-specific tailored structures, they are the essential power tool accessory for every metalworking professional.

| 1/2" Square Drive Electric Wrench Adapter | Cordless/AC Electric Wrenches (1/2" drive) | On-site mobile metal drilling, steel structure construction, field fabrication | 1/2" square male drive | 300-800 N·m |
| Flange Type Core Drill Adapter | Fixed Core Drill Machines | Large-diameter deep hole precision drilling, industrial metal processing, thick steel plate machining | Flange mount (M8/M10 bolt pattern) | 200-600 N·m |
| SDS Plus/SDS Max Electric Hammer Adapter | Rotary Hammers (SDS Plus/SDS Max chuck) | High-hardness metal drilling, thick steel plate, alloy steel machining | SDS Plus / SDS Max shank | 150-400 N·m |
| Triangular Shank Adapter | Standard Electric Drills / Hand Drills | Light-duty metal drilling, thin steel plate, DIY metal fabrication | 6mm / 8mm standard triangular shank | 80-200 N·m |
Product Line Overview & Compatibility
Our annular cutter adapter series includes 4 core models, each designed to match the output characteristics of different power tools, ensuring perfect fit and optimal performance for every metal drilling scenario:
Universal Compatibility
All our annular cutter adapters are fully compatible with leading global power tool brands, including but not limited to: Bosch, DeWalt, Makita, Hilti, Milwaukee, Ryobi, Hitachi (Hikoki). They fit all standard-size annular cutters (6mm-160mm diameter range), making them a one-stop solution for all your metal drilling needs.
Key Product Advantages
1. Premium Material & Precision Manufacturing
- High-Strength Carbon Steel: Forged from high-quality alloy carbon steel, with a quenched and tempered surface treatment (HRC 45-50), delivering exceptional impact resistance, wear resistance, and anti-deformation performance, even under continuous heavy-duty drilling.
- Precision Machining: CNC-machined with ±0.01mm tolerance, ensuring perfect coaxiality between the power tool, adapter, and annular cutter, eliminating radial runout and vibration during drilling.
- Rust & Corrosion Resistance: Black oxide surface treatment provides long-lasting rust protection, suitable for harsh on-site construction and industrial workshop environments.
2. Secure & Anti-Slip Clamping Design
- Dual Locking Screws: Each adapter features 2 symmetrically placed high-strength set screws, ensuring 360° uniform clamping force on the annular cutter shank, completely eliminating slippage during high-torque metal drilling.
- Tool-Specific Locking Mechanisms:
3. Efficiency & Tool Life Extension
- High Torque Transmission: 100% power transfer from the power tool to the annular cutter, reducing energy loss and improving drilling speed by 30% compared to generic adapters.
- Heat Dissipation Design: Optimized cylinder structure reduces heat buildup during continuous drilling, protecting both the annular cutter and adapter from overheating wear.
- Reduced Cutter Damage: Stable coaxial connection prevents annular cutter chipping, bending, and premature wear, extending the service life of your expensive annular cutters by 2-3 times.
4. Versatile Application Scenarios
- Industrial Machining: Precision hole drilling for mechanical parts, steel structure fabrication, and metal sheet processing.
- Construction & Steel Structure: On-site mobile drilling for steel beams, columns, and metal frameworks.
- Fabrication & DIY: Light-duty drilling for home improvement, metal furniture, and custom metal projects.
- Heavy-Duty Drilling: Thick steel plate, stainless steel, and alloy steel machining for industrial manufacturing.
Professional Installation & Usage Guide
Pre-Installation Preparation
- Safety First: Disconnect the power supply of your power tool (remove batteries for cordless tools) to avoid accidental startup.
- Inspection: Check the adapter, annular cutter, and power tool for wear, cracks, or debris. Replace damaged parts immediately.
- Compatibility Check: Confirm the adapter model matches your power tool and annular cutter specifications to prevent overload damage.
Step-by-Step Installation
1. 1/2" Square Drive Electric Wrench Adapter
- Align the adapter's square drive with the electric wrench's 1/2" socket, push firmly until a "click" sound confirms the spring ball lock.
- Rotate the adapter's lock sleeve counterclockwise to open the clamping port.
- Insert the annular cutter shank fully and straightly, then rotate the lock sleeve clockwise to tighten.
- Use a wrench to further fasten the set screws (torque: 50-80 N·m) to prevent slippage.
- Test the connection with a low-speed run to confirm no vibration or runout.
2. Flange Type Core Drill Adapter
- Secure the core drill to a dedicated stand. Remove the original output flange cover and clean the flange surface.
- Align the adapter's flange with the drill's output flange, insert bolts, and tighten evenly in a cross pattern (torque: 40-60 N·m).
- Insert the annular cutter into the clamping cylinder, adjust coaxiality, and lock the side set screws symmetrically.
- Test at low speed to confirm runout ≤0.2mm before formal drilling.
3. SDS Plus/SDS Max Electric Hammer Adapter
- For SDS Plus: Insert the adapter shank into the hammer's chuck, rotate 90° clockwise to lock automatically.
- For SDS Max: Push the hammer's chuck sleeve forward, insert the adapter fully, and release to lock.
- Insert the annular cutter and tighten the lock ring clockwise.
- Test the impact connection at low speed to confirm no disengagement.
4. Triangular Shank Adapter
- Open the electric drill's 3-jaw chuck fully, insert the adapter's triangular shank, aligning the flat surfaces with the jaws.
- Tighten the chuck by hand, then use a chuck key to fasten evenly in 3 directions.
- Secure the small-diameter annular cutter (≤40mm) with the adapter's set screws.
- Test for looseness before use.
Usage & Maintenance Tips
- Speed Matching: Adjust drilling speed based on cutter size and material: 800-1500 RPM for small cutters/thin steel, 100-400 RPM for large cutters/thick stainless steel.
- Cutting Fluid: Use continuous metal cutting fluid during drilling to cool the cutter and adapter, reduce friction, and extend service life.
- Post-Use Maintenance: Clean the adapter with compressed air to remove metal shavings, apply anti-rust lubricant, and store in a dry environment.
- Periodic Inspection: Check clamping force and wear every 3 months; replace the adapter if runout exceeds 0.3mm.
Troubleshooting Common Issues
表格
| Problem | Root Cause | Solution |
|---|
| Annular cutter slips during drilling | Insufficient clamping force, worn clamping port | Retighten set screws; replace adapter if port is worn |
| Abnormal vibration during drilling | Poor coaxiality, loose connection | Reinstall adapter and cutter, check alignment |
| Adapter overheats during use | Overload operation, lack of cutting fluid | Reduce speed/feed, add cutting fluid, lubricate adapter |
| Adapter won't fit power tool | Shank size mismatch, debris in chuck | Confirm adapter model, clean tool chuck thoroughly
