Dremel 454 rotary tool accessory

Precision ground Dremel 454 rotary tool accessories designed for quick and easy sharpening of chainsaw blades. The set includes three burrs with a 3.2 mm shank diameter and 4.8 mm working diameter; each bit is 50 mm long and rated for use at tool speeds up to 30,000 RPM. Compatible with Dremel chainsaw sharpening attachment No. 1453 and a range of Dremel rotary tools, these accessories are intended for detailed sharpening and precision work on chain teeth.

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.
