THANK YOU FOR YOUR INTEREST FOR OUR 1/4 INCH HEX SHANK COARSE CARBON STEEL WIRE BRUSH SETS
First, pls check these Warm Tips before you use:
1. Pls check and make sure it can hold this 1/4 inch shank when installing it to your drill machine. Meanwhile, pls use a special wrench to tighten properly and check whether it is firm and strong.
2. For safety, pls wear the Safety Glasses/Gloves and other protective equipment when working with these wire brush sets.
3. During the grinding, the operator should increase the force slowly and stand on top of the workpiece to prevent it from flying, chipping and hurt.
