Advantages

The Dremel 454 burrs are precision-ground for consistent cutting action and fast material removal when sharpening chainsaw teeth.

How to use

Fit a Dremel 454 burr into the rotary tool collet and tighten according to the tool manufacturer's instructions. If sharpening chainsaw blades, mount the chainsaw sharpening attachment No. 1453 on the rotary tool to maintain the correct filing angle, then run the tool at an appropriate speed—up to 30,000 RPM—while applying light, consistent pressure along each chain tooth. Replace the burr when cutting performance decreases or the profile is worn.

Recommendations

Use eye and hand protection while operating the rotary tool. Verify compatibility of the 3.2 mm shank with your Dremel model and use the 1453 chainsaw attachment for best sharpening results. Allow the burr to cool between extended uses to prevent overheating and premature wear.
