Rotary carbide bits are designed for use in a rotation only drill equipped with a 3 jaw
Jacobs type chuck. The bits meet ANSI standards and can be used to drill in soft or brittle
masonry materials using rotation only. Fast spiral flutes are for fast drilling in soft to
medium masonry materials such as block or brick. Deep fluted drills perform best in
concrete where the wide fluting helps clean concrete chips and dust from the hole.
