Bosch 7 In. Extension SDS-plus for SPEEDCORE Thin-wall Core Bits

The 7-Inch Extension SDS-plus® for SPEEDCORE™ Thin-wall Core Bit from BOSCH lets you get through thicker walls by adding length to your regular bits. It spins at speeds of up to 600 rpm for working at a moderate speed. This Bosch SDS-plus thin-wall core bit is easy to install. Just screw the regular bit into it and you're ready to go. As part of the SDS-plus system, it's compatible with various hammer drills and is easy to swap out with just one hand. The Bosch thin-wall core bit fits cores 1-1/2 inches or longer to give you an overall reach of at least 8 inches. Use it with smaller hammers in cramped quarters or to handle your drilling needs without carrying extra tools.
