The STEWART FASTENER CM9512X4X6 is a CM95-series SDS drill bit designed for rotary hammer applications. It measures 1/2 inch in diameter with a 4-inch flute length and 6-inch overall length. The SDS shank interface provides positive bit retention in SDS-compatible rotary hammers, eliminating the need for a chuck key and allowing quick bit changes under load. This bit is suited for drilling into concrete, masonry, and similar materials in commercial and residential construction and mechanical trades.
This SDS bit is a practical choice for electricians, plumbers, HVAC mechanics, and general contractors who need to core through concrete block, brick, or slab for penetrations, anchor holes, or equipment mounting. The 1/2-inch diameter suits standard anchor and fastener hole requirements common in trade work. The 6-inch overall length provides enough reach for most through-wall and slab applications without requiring an extension.
Designed for use with SDS-chuck rotary hammers; verify your tool accepts standard SDS (SDS-Plus) shank bits before installation, as SDS-Max tools require a different shank profile.
Installation should be performed by a qualified tradesperson following applicable codes. Always power down and unplug or lock out the rotary hammer before inserting or removing the bit. Seat the SDS shank fully into the chuck until the retention mechanism clicks. Wear appropriate PPE including eye protection when drilling into masonry or concrete.
