How the Extended Shank Design Improves Reach and Control
The extended 3" shank lets you get into deeper grooves or hard-to-reach spots that shorter burrs just can’t touch. Imagine trying to reach the back of a narrow bottle neck with your fingers—having a longer reach makes all the difference. Plus, the extended shank combined with double cut flutes reduces chatter and gives you excellent control over the grinder, so the tool feels like a natural extension of your hand. This means less fatigue and more precise results every time.
Installation and Maintenance Guide
Setting It Up
- Ensure the grinder or rotary tool is unplugged before installation.
- Clean the collet or chuck to remove any debris for secure fitting.
- Insert the shank fully into the collet to avoid wobbling during use.
- Tighten the collet nut firmly but do not overtighten to prevent damage.
- Perform a slow speed test run to confirm the burr is properly seated and balanced.
Keeping It Going
- Clean the burr after each use using a wire brush to remove metal shavings.
- Store in a dry place to avoid corrosion on the shank or carbide edges.
- Inspect regularly for dulling or chips and replace when necessary to maintain performance.
- Avoid overheating the burr by using moderate pressure and proper speed settings.
- Lubricate or cool with cutting fluids on tough materials to extend burr life.
