Milwaukee 48-20-9012 Carbide Hammer Drill Bit 1/4 X 12 Inches

Product Description

The Milwaukee Electric Tool Corp 48-20-9012 is a SHOCKWAVE Impact Duty Carbide Hammer Drill Bit engineered for use with impact drivers in demanding drilling applications. Built with a carbide tip, this bit delivers durable penetration through masonry, concrete, and similar hard substrates. The 1/4 inch hex shank seats directly into standard impact driver chucks without a separate adapter. Overall length is 12 inches, providing extended reach for deeper holes or access-restricted drilling situations. This bit ships as a unit of measure of each (EA) and is sold in a package quantity of 3. It weighs 0.32 pounds total.

This bit is suited for residential and light commercial work where an impact driver is the primary tool. Common install scenarios include anchoring into masonry walls, drilling through concrete blocks for conduit, piping, or fastener placement, and similar hard-material penetration tasks. Electricians, plumbers, and general contractors who use impact drivers rather than dedicated rotary hammer tools will find this bit a practical addition to their kit. The carbide construction holds an edge longer than standard steel bits when working in abrasive material.

Key Features

• Carbide tip construction for extended durability in masonry and concrete
• 1/4 inch hex shank for direct chuck compatibility with standard impact drivers
• 12 inch overall length for deep-reach or restricted-access drilling
• SHOCKWAVE Impact Duty design rated for the torque output of impact drivers
• Sold in a package of 3 bits per order unit

Compatibility

Designed for use with impact drivers equipped with a standard 1/4 inch hex chuck. Also compatible with standard drill/drivers or hammer drills that accept 1/4 inch hex shank accessories.

Installation Notes

This bit is installed and used by any trade professional who works with impact drivers or compatible drill/drivers. Ensure the tool is powered off and the battery removed or power disconnected before inserting or removing the bit from the chuck. Wear appropriate eye protection when drilling into masonry or concrete, as carbide-tipped bits generate chips and dust. Follow applicable OSHA and site safety guidelines for rotary tool operation.
