Welcome to TRUTOPWAY, your trusted source for professional woodworking tools! Our 4-in-1 Router Circle Cutting Jig is a game-changing router accessory designed to elevate your woodworking craftsmanship. Whether you're a seasoned carpenter, a passionate DIY enthusiast or a hobbyist, this multifunctional router guide combines precision, durability and versatility to solve all your circle cutting and groove milling challenges.

Detailed Function Analysis
This innovative router jig integrates four essential woodworking functions into one compact tool: perfect circle cutting, precise groove milling, accurate center engraving and reliable right angle measurement. Crafted from high-grade aluminum alloy with CNC machining, it offers superior rigidity and stability, eliminating vibration during operation for clean, professional results every time.
As a premium circle router jig, it features an adjustable sliding rail that allows you to set the radius from 7.5cm to 40cm (2.95" to 15.75"), making it ideal for creating everything from small decorative circles to large table tops. The laser-engraved scale markings are clear and wear-resistant, ensuring precise measurements for consistent results.
The removable aluminum base is a standout feature, transforming this tool into a versatile router edge guide and slot-milling holder. It fits most compact routers and trimmers with diameters between 6cm and 10cm (2.36" to 3.94"), making it compatible with most popular wood router brands on the market. This design not only enhances the tool's functionality but also saves you money by eliminating the need to purchase multiple router jigs and guides.

Usage Guide
Using this router circle cutting jig is simple and straightforward:
Assembly: Attach the removable aluminum base to your router using the included screws (ensure your router's hole spacing matches the base).
Radius Adjustment: Loosen the locking knob, slide the rail to your desired radius using the laser-engraved scale, then tighten the knob securely.
Circle Cutting: Fix the center pin to your workpiece at the desired center point, turn on your router, and slowly rotate the jig around the center pin to cut a perfect circle.
Groove Milling: Remove the center pin, adjust the guide to your desired groove position, and slide the router along the edge of your workpiece to create straight, uniform grooves.
Important Note: Always wear appropriate safety gear when operating power tools. Ensure your router is securely fastened to the base before use, and test the setup on a scrap piece of wood first.

Maintenance & Care
To ensure the long-term performance and accuracy of your TRUTOPWAY router jig, follow these simple maintenance tips:
After each use, wipe the tool with a clean, dry cloth to remove wood dust, debris and moisture.
Apply a light coat of lubricant to the sliding rail and locking mechanism periodically to ensure smooth operation.
Avoid dropping or hitting the jig against hard surfaces, as this may damage the precision components and affect accuracy.
Store the jig in a dry, ventilated place away from extreme temperatures and humidity to prevent corrosion.
Inspect the base and screws regularly for wear and tear, and replace any damaged parts promptly.
This 4-in-1 router circle cutting jig is more than just a tool—it's an investment in your woodworking success.
