If you’ve ever fired up a chop saw (or abrasive cutoff saw) to slice through steel, aluminum, or other ferrous metals, you know the drill: the satisfying cut is followed by a chaotic spray and pile of sharp, hot metal shavings everywhere. They scatter across the floor, get tracked into the house, clog shop vacs, and create serious cut hazards. Sweeping them up is tedious and risky.
Enter a simple but brilliant workshop tool: the DTLHCNCT 180 LB On/Off Magnet (full title: DTLHCNCT 180 LB ON/Off Magnets, Magnetic Welding Holder, Multipurpose Switch Magnet for Lifting and Handling, Metal Screening, Weld Positioning, Metal Salvage).
This compact, powerful switchable permanent magnet is designed exactly for jobs like yours — catching and containing metal debris quickly and cleanly.
Unlike a standard fixed magnet that stays “stuck” until you pry everything off (risking cuts), this one features a clever on/off lever.
- ON position: Delivers up to 180 lbs of pull force (professionally tested), strongly attracting and holding ferrous metal shavings, chips, screws, nuts, and small parts.
- OFF position: Instantly releases the collected material — it drops cleanly into a bin or bucket with zero fuss.
Built from durable alloy steel with a bright red top and silver base, it’s compact, portable, and built for real workshop abuse. It comes with clear instructions and is marketed for metal screening, machining/welding positioning, lifting/handling, and salvage work.Perfect Use Case: Catching Shavings from Your Chop SawThis is where the magnet truly shines for metal fabricators and DIYers. Here’s how to put it to work:
- Place the magnet on a metal tray, stand, or directly on the floor/table near your chop saw (it magnetically attaches to ferrous surfaces).
- Flip the lever to ON before you start cutting.
- As you cut, falling and flying shavings are drawn to the magnet instead of scattering everywhere.
- When you’re done, hold the magnet over a scrap bucket or recycling bin and flip it to OFF. The entire pile of shavings drops out cleanly — no stuck pieces, no finger cuts from sharp debris.
Pro tip: For maximum effectiveness with flying shavings, position it slightly below or to the side of the cut zone and combine it with a simple shield or your existing dust collection setup. The on/off feature makes post-cut cleanup ridiculously fast.
Many users already love these switch magnets for general shop cleanup and metal separation. Your chop-saw application is a natural extension of its “metal screening” and “machining positioning” capabilities.
This isn’t a one-trick pony:
- Welding & fabrication — Hold and position metal pieces securely while you tack or weld.
- Lifting & handling — Pick up dropped fasteners or small-to-medium metal parts.
- General cleanup — Sweep or place it near grinders, drills, or mills to catch filings.
- Salvage/screening — Separate metal from wood, plastic, or other debris.
