Milwaukee 48-20-7411 Sds Carbide Drill Bit 3/16x4x6 in

Product Description

The Milwaukee Electric Tool Corp 48-20-7411 is a 44 Magnum SDS carbide drill bit engineered for use with SDS rotary hammers. It measures 3/16 inches in diameter with a 4-inch maximum drilling length and 6-inch overall length. The bit features a unique tip geometry combined with a 4-flute design that delivers up to 25% longer drilling life and faster cutting speeds compared to standard SDS bits. The geometry also allows for easier centering at the start of each bore, reducing wander on hard surfaces. Reduced vibration output contributes to operator comfort during extended use. Licensed HVAC, plumbing, and electrical contractors regularly rely on SDS bits of this type for penetrations through concrete, block, and masonry.

This bit is suited for residential and light commercial applications where SDS rotary hammer use is required. Typical scenarios include drilling anchor bolt holes in concrete slab, running conduit or pipe penetrations through block walls, and setting anchor hardware in poured concrete. The 3/16-inch diameter is a common size for drop-in anchor and sleeve anchor pilot holes. The 4-flute design improves chip evacuation in deep-hole drilling, keeping the bit running cooler and reducing the chance of binding in cured concrete.

Key Features

• 44 Magnum carbide tip for extended wear life in hard masonry and concrete
• 4-flute design provides up to 25% longer drilling life and faster material removal
• Unique tip geometry enables easier bit centering at hole start
• 4-flute flute configuration lowers vibration for improved operator comfort
• SDS shank fits any standard SDS rotary hammer chuck
• 4-inch maximum drilling length suitable for common anchor and penetration depths

Compatibility

Designed for use with any SDS rotary hammer accepting a standard SDS shank bit.

Installation Notes

This bit is installed and used by licensed electricians, plumbers, HVAC technicians, and general contractors performing masonry penetrations. Always power down the rotary hammer and disconnect it from the power source before changing bits. Wear appropriate eye protection and dust control measures when drilling concrete or masonry, as required by applicable OSHA and jobsite safety standards. Do not use this bit with standard drill chucks — it requires an SDS-compatible rotary hammer.
