Milwaukee 3/4 in. Keyed Chuck for No. 3 Taper
Model Number: 48-66-2000
The Milwaukee 48-66-2000 is a genuine OEM Milwaukee 3/4 in. keyed chuck replacement for Milwaukee right-angle drills, hole hawg drills, and magnetic drill presses that use a No. 3 morse taper spindle. The drill chuck is the fundamental interface component between the tool's spindle and the drill bit or cutter being driven — chuck condition directly determines hole quality, dimensional accuracy, and bit retention safety during drilling operations. A worn chuck exhibiting excessive runout, jaw slippage, irregular gripping, or damaged jaw threads produces oversized holes with poor dimensional tolerance, allows bit movement that can damage the workpiece during hole entry, and creates a safety hazard if bit slippage occurs under drilling load. Replacing a worn chuck with a genuine Milwaukee OEM part restores the original dimensional specifications for taper fit accuracy, jaw gripping range, jaw thread condition, and overall chuck runout performance. This is a keyed chuck design requiring the use of a chuck key to open and close the jaws for bit installation and removal — the keyed design provides higher clamping force than keyless chucks for heavy-duty hole hawg and right-angle drill applications.
The No. 3 taper specification refers to the internal Morse Taper bore machined into the chuck's mounting shank — Morse Taper No. 3 is a standardized taper angle and diameter that must precisely match the corresponding Morse Taper on the drill spindle for correct seating, accurate alignment, and safe retention under drilling forces. Installing a chuck with an incorrect taper number on a drill spindle will result in improper seating, misalignment, excessive runout, and potential chuck ejection during drilling — always verify the exact Morse Taper number of your specific Milwaukee drill's spindle before selecting a replacement chuck. Milwaukee tool specifications, including chuck taper size, vary by model number and can also vary by production serial number range within the same model designation — consult Milwaukee's official service parts lookup tool at milwaukeetool.com or reference the service parts diagram for your specific tool model and serial number to confirm the correct chuck specification before ordering.
Genuine Milwaukee OEM replacement chucks ensure the correct dimensional specifications, metallurgical quality, and performance characteristics required for safe, accurate operation in professional Milwaukee drilling equipment — do not substitute non-OEM chucks with potentially incorrect taper specifications or inferior material quality in professional power tool applications.
