Milwaukee Tool 48-20-8040 Sds-plus Drill Bit 8mm

Product Description

The MILWAUKEE TOOL 48-20-8040 is a carbide-tipped rotary hammer drill bit designed for use with SDS-Plus rotary hammers. The 8mm diameter bit features a spear-style cutting tip ground from carbide-tipped high speed steel, delivering the impact resistance and edge retention needed for drilling into concrete, masonry, and block. With a usable flute length of 100mm (approximately 3.94 inches) and an overall length of 160mm (approximately 6.30 inches), it suits standard depth-of-drive requirements on most residential and light commercial masonry work. The SDS-Plus shank provides positive locking engagement in compatible chuck systems, eliminating bit slippage under rotary-hammer impact loads. Electricians, plumbers, HVAC technicians, and general contractors reach for this bit when penetrating concrete walls or block for sleeve anchors, conduit, or pipe passage.

This bit is suited for rotary hammer applications in residential and commercial construction, remodeling, and mechanical trades where masonry penetration is required. Typical use cases include drilling anchor holes in poured concrete, CMU block, and brick for equipment mounting, structural fasteners, and utility penetrations. The 8mm diameter is a common size for wedge anchors and sleeve anchors used in mechanical and electrical equipment installation.

Installation Notes

Installation should be performed by qualified trade professionals familiar with rotary hammer operation and applicable codes. Ensure the rotary hammer is powered off and unplugged before inserting or removing the bit. Confirm the bit is fully seated and locked in the SDS-Plus chuck before beginning drilling. Eye protection and dust control measures are recommended when drilling concrete or masonry per standard jobsite safety practice.
