15-Piece Drill Chuck Collet Kit for Dremel

This NSI set supplies 15 collets covering shank diameters from 0.5 mm to 3.2 mm, plus a keyless chuck and brass collets with metal nuts. It is designed for owners of Dremel rotary tools who need a complete range of bit holders in one package.

Shank Range 0.5 mm to 3.2 mm

The collets accept accessories from 1/32 inch up to 1/8 inch, covering drill bits, sanding drums, polishing wheels, wire brushes and cut-off wheels. Light-duty tasks are well supported, but heavier cutting or high-torque drilling will exceed the holding capacity of these small shanks.

Keyless Chuck with Brass Collets and Metal Nuts

The spring-loaded keyless chuck secures bits without tools, while brass collets resist wear and metal nuts avoid the breakage common with plastic versions. In normal rotary-tool use the assembly runs cool and quiet, adding minimal vibration to the hand piece.

Highlights

  • Secure grip from keyless chuck spring preventing bit release
  • Wide shank range 0.5mm to 3.2mm covers 15 collet sizes
  • Brass collets resist wear and hold bits firmly at speed
  • All-metal nuts replace plastic for durability and stability

Questions about this item

Will the 4486 keyless chuck fit the collets from my older Dremel rotary tool?

The 4486 keyless chuck accepts shank sizes from 1/32" to 1/8" and works with the included 4485 brass collets in sizes .5, .8, 1.0, 1.2, 1.5, 1.8, 2.0, 2.4, 3.0, and 3.2mm.

How can I confirm the 4486 keyless chuck is gripping bits securely after I install it?

The built-in spring in the 4486 keyless chuck provides a positive lock; test by hand-tightening a bit and verifying it does not pull out under light pressure before starting the rotary tool.

Does the 15-piece set include the 4486 keyless chuck, 4485 brass collets, and metal nuts, or must I buy any of those separately?

The 15-piece set contains the 4486 keyless chuck, ten 4485 brass collets (.5 to 3.2mm), and the required metal nuts — no extra components are needed for operation.
