What Are Routers?
Routers are power tools that rotate a grinding stone attached to their shafts for polishing tasks. These tools are ideal for intricate work in complex shapes or tight spaces, making them useful in industries for polishing curved surfaces and deburring, as well as in crafts for carving on wood or glass.
The grinding stone, known as a bit, is secured in the router’s chuck. A variety of bit types can be selected based on the task at hand.
How to Use Routers
Before starting, attach the desired bit to the router’s tip using the collet chuck. Once the router is activated, wait for the rotation to stabilize before bringing it close to the target object. Stable rotation is crucial for effective polishing.
When using routers, observe the following safety measures:
- Wear protective goggles and gloves to shield against burrs or sparks.
- Avoid getting hands or body close to the rotating bit.
How to Choose a Router
In selecting a router, consider the work environment and the bit you intend to use. Routers are available in AC-powered and cordless models, each with specific advantages.
- AC-powered routers are restricted by a power cord, but are generally more consistent for extended use.
- Cordless routers offer workspace flexibility, but may be less ideal for prolonged tasks due to battery weight.
Ensure compatibility between the collet chuck and the router’s shaft diameter. Also, check the maximum tool diameter the router can accommodate, which varies from 25 to 49 mm. For versatile use, consider routers with adjustable rotation speeds, ranging from 7,000 to 29,000 rotations per minute.
