Milwaukee 48-20-9162 Carbide Hammer Drill Bit 1/4x6 in 5-pack

Product Description

The Milwaukee Electric Tool Corp 48-20-9162 is a 5-pack of SHOCKWAVE Impact Duty carbide-tipped hammer drill bits designed for use in rotary hammer and hammer drill applications. Each bit measures 1/4 inch in diameter with a 4-inch working length and 6-inch overall length. The carbide tip is engineered to withstand the repeated impact and rotational stress of drilling into concrete, masonry, and block. These bits are a standard choice for electricians, plumbers, and HVAC techs who core anchor holes or conduit penetrations through concrete or CMU on commercial and residential job sites.

The 48-20-9162 bits are well-suited for light to medium masonry drilling tasks, including anchor hole placement, through-penetrations in concrete block, and setting fasteners in poured concrete slabs or walls. The 1/4-inch diameter makes them a go-to size for sleeve anchors, drop-in anchors, and similar hardware commonly used in mechanical and electrical rough-in work. The 5-pack format supports high-volume drilling where bit wear is a regular factor on jobsites.

Key Features

• Carbide tip rated for impact duty in hammer drill applications
• 1/4 inch diameter x 4 inch flute length x 6 inch overall length per bit
• SHOCKWAVE construction designed to resist tip fracture under repeated impact
• 5-pack format reduces downtime from bit wear on production drilling tasks
• Compatible with standard SDS-plus and keyed chuck hammer drills accepting 1/4-inch shank

Compatibility

Designed as an OEM-style replacement or consumable for hammer drills and rotary hammers accepting a 1/4-inch round or hex shank bit in standard chuck configurations.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with rotary hammer operation and applicable codes. Always wear eye protection and confirm the drill is set to hammer mode before use in masonry. Inspect bits for carbide tip damage or shank wear before each use and replace any bit showing cracks or excessive wear. Do not use hammer drill bits in rotation-only mode on hard masonry, as this will accelerate tip wear and can cause bit failure.
