Milwaukee 48-20-9052 Carbide Hammer Drill Bit Set 7pc

Product Description

The Milwaukee 48-20-9052 is a 7-piece carbide hammer drill bit set designed for demanding concrete, masonry, and hard-surface drilling applications. Built on a 1/4 inch hex shank platform, these bits seat directly into impact drivers and hammer drills without a chuck key. The carbide construction delivers extended cutting life compared to standard steel bits. This set is part of the SHOCKWAVE Impact Duty line, engineered to handle the torque and vibration loads generated by modern impact drivers in trade and jobsite use. Licensed electricians, plumbers, HVAC techs, and general trade contractors reach for this set when anchoring into concrete block, CMU, or brick.

This bit set is suited for residential and light commercial applications where drilling into masonry substrates is a routine part of rough-in or finish work. Typical scenarios include setting anchor points for pipe hangers, conduit straps, equipment mounts, and electrical boxes in concrete or block walls. The 1/4 inch hex shank makes these bits compatible with any impact driver or hammer drill that accepts a standard 1/4 inch hex quick-change chuck, eliminating the need for a separate SDS-style tool for light-to-medium masonry work.

Key Features

• Carbide construction for extended durability in concrete and masonry
• 1/4 inch hex shank seats in standard quick-change impact driver chucks
• 7-piece set covers a range of common bit sizes for varied anchor and fastener applications
• SHOCKWAVE Impact Duty design handles high-torque and vibration loads from impact drivers
• No chuck key required — fast bit changes on the jobsite

Compatibility

Designed for use with impact drivers and hammer drills that accept a standard 1/4 inch hex shank. Suitable for drilling into concrete, masonry, and similar hard substrates.

Installation Notes

Insert the 1/4 inch hex shank fully into the tool chuck before applying power. Always wear eye protection and a dust mask when drilling into concrete or masonry, as silica-bearing dust is a respiratory hazard. Confirm the tool is set to hammer mode when drilling into hard masonry to avoid premature bit wear. Follow all applicable jobsite safety codes and OSHA standards for masonry drilling operations.
