## Description

Some examples of these chemicals are:lead from lead-based paints,crystalline silica from bricks and cement and other masonry products, andarsenic and chromium from chemically treated lumber.Your risk from exposure to these chemicals varies, depending on how often you do this type of work.

Review: Great bits. Strong and sharp, reasonable deal. Learning how to drill different metals is just as important as buying good drill bits. These are good bits if they are used properly. Educate yourself on technique and these bits will last a long time.
Review: They work as advertised and are way cheaper than bits from the hardware stores I go to. I've had to drill holes through a number of thin steel plates and I'm still on my first bit after 30 holes. It is drilling slower so I'll start using the next one and leave first one for my plastic or wood drilling applications. Also love the small case it comes with. Will definitely buy again in the next size I need.
