Frequently Asked Questions
Can I use hole saws on a cordless drill for fence posts?
Yes — many hole saw kits (like HYCHIKA and ASNOMY) are compatible with standard cordless drills. Use proper pilot bits, steady pressure, and low speed for metal. For large-diameter or thick metal, a drill with higher torque or a drill press/magnetic base is safer and more effective.
How do I prevent carbide teeth from chipping?
Avoid forcing the cutter and use appropriate speed and cutting fluid on metal. Let the cutter do the work, use pilot bits to stabilize, and back out frequently to clear chips. Carbide is brittle but very hard — misuse or side-loading increases chip risk.
Are Dremel rotary accessories good for outdoor use?
Yes for trim, sanding, small cuts and polishing — Dremel kits offer great versatility for finish work on decks and patios. However, smaller Dremel bits are not meant for heavy structural metal cutting; choose dedicated hole saws or carbide cutters for that.
