Rotozip Spiral Saw Fit The Rotozip Collets and Nut Kit CN1 is made for RotoZip Spiral Saws and supports ZipBits, XBits, and XCores, giving you a straightforward replacement or size-change kit for your cutting setup.
Overview
Rotozip Collets and Nut Kit CN1 is a replacement accessory kit for RotoZip spiral saws. This is a collet and nut kit designed for holding different accessory shank sizes in a spiral saw. Model Number: CN1. If your current collet is worn, damaged, or limited to one accessory size, this kit gives you the parts needed to get the tool back in service with more flexibility.
The big value here is simple: you get three collet sizes in one package, including 1/8 in, 5/32 in, and 1/4 in, plus the matching nut. That matters because RotoZip users often switch between different cutting accessories depending on the job. Instead of hunting for individual parts, this kit lets your spiral saw accommodate multiple accessory sizes with the proper clamping hardware.
RotoZip builds these parts from stress and fatigue-proof steel, which is exactly what you want in a collet. A collet has one job: grip the accessory shank consistently when the tool is running at speed. Material quality matters because repeated tightening and loosening can wear out lower-grade parts fast. Good steel helps maintain holding power and reduces the chance of slippage from a tired collet.
For practical use, this is the kind of small part that can make the difference between a tool that is ready to work and one that sits in the truck. If your existing nut is rounded off or your collet no longer clamps cleanly, swapping in fresh parts is a smart fix. It is also a handy kit to keep around if you use different accessory diameters regularly and do not want downtime in the middle of a cut.
Compatibility is clear and specific. This kit is intended for RotoZip Spiral Saws and is listed for use with ZipBits, XBits, and XCores. That makes it a good fit for users already working inside the RotoZip accessory system who need the right collet size for the accessory they are running.
Who should buy it? Anyone maintaining a RotoZip spiral saw, especially contractors and serious DIY users who rely on the tool for repeated accessory changes. If you need a clean, correct way to fit multiple accessory sizes without guessing on aftermarket parts, this is the right kind of kit: small, specific, and useful.
