Designed with a sturdy ¼" hex shank for quick change, the hole saws provide a solution for creating holes that can be used with hammer drills.

Here are the key features:

• Uses a thin wall, 8 TPI design for burr-free cutting up to 40% faster than standard bi-metal hole saws.
• Includes a spring ejector that eliminates the need for manual removal of the plugs by automatically ejecting the material.
• The shoulder stop design prevents over-drilling and potential damage to the internal components of electrical boxes.
• Suitable for use on plastics and thin metals up to 1/8" thick.
