Milwaukee 48-20-7432 Sds Plus Drill Bit 1/4 X 8 Inch

Product Description

The MILWAUKEE 48-20-7432 is a 2-cutter SDS Plus rotary hammer drill bit engineered for general concrete and masonry drilling in both corded and cordless rotary hammers. The bit measures 1/4 inch in diameter with an 8-inch overall length and 6-inch working length. A variable flute geometry accelerates debris extraction, which sustains drilling speed and extends runtime per battery charge in cordless applications. The breaker point pulverizes material ahead of the cutters, improving penetration rate. A reinforced flute reduces vibration during extended use. Licensed HVAC, plumbing, electrical, and general construction tradespeople install this bit when core drilling through concrete slab, block, or hard aggregate is required.

This bit is suited for residential and commercial jobsite drilling in poured concrete, hard aggregate, and rebar-bearing masonry. It is compatible with any SDS Plus chuck rotary hammer, corded or cordless, making it a common choice when running conduit penetrations, anchor bolt holes, and pipe sleeve openings through structural concrete. The variable flute design is particularly effective in cordless rotary hammers where maintaining holes-per-charge efficiency is a priority.

Key Features

• 2-cutter SDS Plus shank fits all SDS Plus rotary hammers, corded and cordless
• Variable flute geometry maximizes debris extraction for sustained drilling speed
• Breaker point pulverizes material ahead of cutters for faster penetration
• Enhanced rebar guards increase durability in hard aggregate and rebar-bearing concrete
• Centering tip enables accurate spot drilling without bit walking
• Wear mark indicator shows when the bit diameter no longer meets ANSI requirements
• Reinforced flute design minimizes vibration during prolonged use

Compatibility

Designed for use with SDS Plus chuck rotary hammers in corded and cordless configurations for general concrete drilling applications.

Installation Notes

Installation is performed by qualified tradespeople familiar with rotary hammer operation. Confirm the tool chuck is an SDS Plus type before inserting the bit — do not force an SDS Plus bit into an SDS Max or spline chuck. Wear appropriate PPE including eye protection and hearing protection during concrete drilling. Inspect the wear mark indicator periodically and retire the bit when the diameter falls below ANSI tolerance.
