Milwaukee Tool 48-20-8056 Sds-plus Drill Bit 12mm

Product Description

The MILWAUKEE TOOL 48-20-8056 is a carbide-tipped SDS-Plus rotary hammer drill bit designed for use in rotary hammer drills on masonry, concrete, and similar hard substrates. At 12mm in diameter with a 110mm usable flute length and 160mm overall length, this bit delivers consistent material removal in demanding drilling applications. The spear cutting shape improves penetration and helps clear debris from the bore. Licensed electricians, plumbers, HVAC technicians, and general contractors reach for SDS-Plus bits when core drilling or anchor-hole drilling is required during rough-in work.

This bit fits any SDS-Plus rotary hammer and is suited to residential and light commercial applications where 12mm diameter holes are required - common when setting concrete anchors, installing conduit supports, hanging pipe hangers, or penetrating masonry walls. The carbide-tipped construction handles repetitive use in aggregate-heavy concrete and block without premature wear compared to standard high-speed steel bits.

Key Features

• 12mm diameter with spear cutting tip for fast, accurate masonry penetration
• Carbide-tipped cutting edge resists wear in concrete, block, and aggregate
• 110mm usable flute length provides effective chip clearance during deep drilling
• 160mm overall length suits standard rotary hammer chuck depth and reach requirements
• SDS-Plus shank locks into compatible chucks without the need for a key

Compatibility

Designed for use with any SDS-Plus rotary hammer drill. The SDS-Plus shank is the standard interface across a wide range of rotary hammer tools used in residential and commercial trade applications.

Installation Notes

Installation of this bit is performed by a qualified tradesperson using an SDS-Plus rotary hammer. Insert the bit fully into the chuck until it locks, and confirm it is seated before drilling. When drilling overhead or near existing utilities, verify the work area is clear of embedded conduit, rebar, or pipe before starting. Follow applicable OSHA standards and site safety protocols when operating rotary hammers in confined or occupied spaces.
