Milwaukee 48-20-9011 Carbide Hammer Drill Bit 1/4x6 in

Product Description

The Milwaukee Electric Tool Corp 48-20-9011 is a SHOCKWAVE Impact Duty carbide hammer drill bit designed for use with impact drivers in masonry and concrete drilling applications. The bit features a 1/4-inch hex shank and measures 1/4 inch in diameter by 6 inches in overall length, with a 4-inch usable drilling depth. Constructed from carbide, it is built to withstand the rotational and impact forces generated by modern impact drivers. Licensed tradespeople and skilled DIYers working with concrete, block, or masonry will find this bit suited to demanding fastening and anchor-hole tasks.

This hammer drill bit is intended for use in residential and light commercial applications where anchor holes or fastener pilot holes must be driven into concrete, block, or similar masonry substrates. It pairs with 1/4-inch hex impact drivers commonly used by electricians, plumbers, and general contractors for setting anchors or drilling through masonry without switching to a dedicated rotary hammer. The SHOCKWAVE design is built to handle the torsional shock loads produced during impact-driver-assisted drilling.

Key Features

• Carbide construction for durability in masonry and concrete drilling
• 1/4-inch hex shank for direct compatibility with impact drivers
• 6-inch overall length with 4-inch usable drilling depth
• SHOCKWAVE Impact Duty design rated for impact driver torsional loads
• Sold as a single unit (each)

Compatibility

Designed for use with impact drivers accepting a 1/4-inch hex shank. Suitable for drilling into concrete, block, and masonry substrates where a hammer drill or impact driver with hammer mode is available.

Installation Notes

Installation should be performed by a qualified tradesperson following applicable safety guidelines. Ensure the impact driver is powered off and the battery is removed before inserting or removing the bit. Wear appropriate eye protection when drilling into masonry, as debris and fragments are generated during operation. Do not use this bit with a standard drill driver in place of a hammer drill or impact driver, as it is designed specifically for impact-rated tools.
