Description
Overview:
The Spindle for DeWalt D21441 and D21720 drills is a genuine DeWalt/Black & Decker replacement part designed to restore smooth, accurate drive in your tool. Made from robust metal, it sits within the drill's drive train to transfer power from the gearbox to the chuck while maintaining alignment and concentricity. This helps reduce wobble and preserves drilling accuracy across everyday tasks. As a direct replacement for OEM No. 494630-00, it fits correctly without modification and supports reliable performance on site and in the workshop. Suitable for selected DeWalt corded drills, including the D21441 and D21720, it is a practical choice for routine maintenance or repairs when the original spindle shows wear or damage.
Key Features:
- Genuine DeWalt/Black & Decker part for assured compatibility and quality
- Direct replacement for OEM No. 494630-00 to simplify sourcing and fitting
- Durable metal construction for long service life under regular use
- Precision fit to maintain spindle alignment and reduce run-out at the chuck
- Supports smooth power transfer for consistent drilling performance
- Straightforward installation using standard workshop tools to minimise downtime
- Suitable for everyday site and workshop conditions across a range of materials
Typical Applications:
Used during routine drill servicing or when symptoms such as excessive chuck wobble, noise, or poor drilling accuracy suggest spindle wear. Ideal for restoring performance when drilling into timber, metal, plastics, and masonry with compatible DeWalt corded drills in trade, maintenance, or DIY settings.
Also known as:
Drill spindle, spindle shaft, output spindle, drive spindle, chuck spindle, drill output shaft, arbor (drill arbor). These terms are commonly used to describe the same rotating component that supports and drives the chuck in compatible DeWalt drills.
