FAQ's: Carbide Drills

Yes—carbide bits excel at cutting stainless steel with proper speed, feed, and lubrication.

Tungsten carbide is costly to produce and machine, plus it offers superior performance and lifespan.

Cobalt is better for general hard metal work; carbide tipped is best for extreme hardness or abrasive materials.

For most metals—nothing. For masonry, diamond bits can outperform carbide in speed and durability.

Longer life, better heat resistance, faster cutting, and the ability to drill harder materials.

Drilling through masonry, concrete, tile, hardened steel, and other tough materials.

No. Carbide tipped uses tungsten carbide inserts; diamond tipped uses bonded diamond grit for cutting.

The cutting edges will be visibly brazed onto the steel body, often a different color or texture.

Look for a silver or gray insert at the cutting edge—different from the bit’s main body.

With proper use, they can outlast HSS by 10–20 times, especially in hard materials.

They’re extremely hard but brittle—excessive side pressure or flexing can cause breakage.

Yes, but you’ll need a diamond grinding wheel—standard grinders won’t work.

Yes. Many scrap yards and tool suppliers buy used carbide for recycling.

No. Titanium-coated bits are still HSS underneath. Carbide is harder and more wear-resistant.

For stone, tile, and glass—yes, diamond is better. For metal, carbide outperforms diamond bits.

Not for the hardest materials. Cobalt is tougher and more forgiving, but carbide stays sharper longer and handles extreme hardness better.

Yes—if you drill hard materials like stainless steel, cast iron, or hardened alloys. They cut faster, stay sharp longer, and handle heat better than HSS.
