مثقاب ثقب كربيد TCT 1 بوصة مع مثقب فورستنر 1 بوصة ومثقاب قطع معدني Drill Hog

Needed a clean 1" hole in a steel project box and this carbide-tipped cutter went through with almost no burrs, way cleaner than the bi-metal ones I've trashed. The 3" overall length gave me enough reach to clear the chuck, and the tungsten carbide teeth still look sharp after a dozen holes.

I've used a lot of hole saws that leave ragged edges, but this carbide-tipped one cut through my metal project with zero burrs, just clean holes. The 3-inch overall length gave me enough reach to get through the material without the chuck rubbing.

Bored six holes through 1/8" steel plate for a bracket project and every one came out clean with no burrs to file down. The carbide tips still feel sharp after that, which surprised me for the price.
