Stewart Fastener CM9514X4X6 Sds Bit 1/4 X 4 X 6

Product Description

The STEWART FASTENER CM9514X4X6 is a CM95-series SDS drill bit sized at 0.25 inches in diameter, 4 inches in working length, and 6 inches in overall length. SDS bits use a slotted shank that locks into SDS and SDS-Plus rotary hammer chucks, allowing the chuck to drive the bit forward with a hammering action while the bit rotates. This combination of rotation and percussion makes the CM9514X4X6 effective for drilling into concrete, masonry, block, and similar hard substrates. Electricians, plumbers, HVAC techs, and general contractors reach for SDS bits when running conduit anchors, pipe hangers, or equipment mounting hardware through concrete slabs and masonry walls.

This bit is suited for light-diameter anchor and fastener pilot holes in residential and commercial construction and service work. The 0.25-inch diameter is a common size for concrete anchor pilots used with threaded rod, drop-in anchors, and screw anchors. The 4-inch flute length provides adequate depth for standard slab and block penetrations, while the 6-inch overall length keeps the bit clear of hammer body obstructions in tight spaces. Trade professionals installing mechanical, electrical, or plumbing systems in concrete-framed or masonry structures will find this a standard working bit.

Compatibility

Designed for use with SDS and SDS-Plus rotary hammer drills. No specific tool model compatibility data was provided in the product input.

Installation Notes

SDS bits are installed and removed by a licensed or qualified tradesperson using a compatible SDS or SDS-Plus rotary hammer — standard keyless chucks will not accept SDS shanks. Always disconnect or power down the tool before changing bits. Wear appropriate eye and hearing protection when operating rotary hammer equipment in concrete or masonry. Follow applicable OSHA silica dust regulations when drilling concrete, and use vacuum shrouds or wet methods where required.
