Bosch hcfc2041b25 Sds-plus Bulldog Extreme Bit 25 Pack

Product Description

The BOSCH hcfc2041b25 is a 25-pack of SDS-Plus Bulldog Extreme rotary hammer drill bits sized at 1/4 inch diameter with a 4-inch working length and 6-inch overall length. These bits are designed for use in SDS-Plus rotary hammers, delivering high-speed drilling into concrete, masonry, and block. The SDS-Plus shank provides secure tool-free bit retention and efficient hammer energy transfer. The multi-pack format suits contractors and tradespeople who need consistent bit supply across multiple jobsites or extended drilling applications.

These bits are suited for residential and commercial concrete drilling tasks, including anchor hole installation, conduit penetrations, and structural fastening applications. Electricians, plumbers, HVAC technicians, and general contractors routinely use SDS-Plus bits for penetrations through concrete slabs, block walls, and masonry substrates. The 1/4-inch diameter is a common size for drop-in and sleeve anchors used in mechanical and electrical rough-in work.

Installation Notes

Insert the SDS-Plus shank fully into the chuck until the bit locks into place before drilling. Always wear appropriate eye and hearing protection when operating a rotary hammer. Ensure the hammer is set to the correct mode for the application — rotary hammer mode for concrete drilling.
