Nonsparking Drill Bits
Drill safely in flammable environments. Made of Factory Mutual (FM) approved beryllium copper, these bits won’t create sparks that could ignite if they made contact with combustible vapors or residues. These drill bits help you meet OSHA requirements in areas such as mines, refineries, and chemical plants where flammable materials are present.
Do not use these bits in direct contact with acetylene. Dust from beryllium copper can be toxic, so don't grind or sharpen them.
