Buying advice

Consider the materials you'll be cutting most often. For heavy-duty or repetitive work, invest in carbide or diamond bits. For occasional DIY, a multi-pack of reinforced cutting wheels offers good value. Always match the mandrel size (usually 1/8-inch shank) to your tool. Check reviews for disc thickness and breakage reports.
