Milwaukee Tool 48-20-8031 Sds-plus Drill Bit 7mm

Product Description

The MILWAUKEE TOOL 48-20-8031 is a carbide-tipped rotary hammer drill bit designed for SDS-Plus rotary hammer tools. It features a 7mm diameter and a spear cutting shape optimized for drilling into masonry, concrete, and similar hard substrates. The bit measures 160mm overall length with a 100mm usable flute length, giving tradespeople sufficient depth capacity for common anchor and fastener applications. The carbide-tipped construction provides durability in abrasive materials where standard high-speed steel bits wear prematurely. Weighing approximately 0.13 pounds, this is a compact, single-piece consumable suited for both light and repetitive drilling tasks.

This drill bit is intended for use in SDS-Plus rotary hammers across residential and light commercial jobsites. Typical applications include drilling anchor holes in concrete block, poured concrete, and brick for electrical conduit supports, pipe hangers, mechanical equipment mounting, and structural fasteners. It is a fit for electricians, plumbers, HVAC installers, and general mechanical contractors who use SDS-Plus tools as standard equipment.

Key Features

• 7mm diameter with spear cutting geometry for clean entry in masonry and concrete
• SDS-Plus shank for secure, tool-free bit changes on compatible rotary hammers
• Carbide-tipped cutting edge for extended service life in abrasive materials
• 100mm usable flute length accommodates standard anchor depths
• 160mm overall length provides working clearance in tight spaces
• Lightweight at 0.13 pounds for reduced tool fatigue during repetitive drilling

Compatibility

Designed for use with SDS-Plus rotary hammer tools. The SDS-Plus shank is an industry-standard interface compatible with SDS-Plus chucks from major rotary hammer manufacturers.

Installation Notes

Install and remove SDS-Plus bits only when the rotary hammer is powered off and unplugged or the battery pack removed. Confirm the bit is fully seated and locked in the chuck before operation. Eye protection and hearing protection are required per standard jobsite safety practice when operating rotary hammers. Follow applicable OSHA and local safety codes for drilling into concrete or masonry, including silica dust controls where required.
