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

With proper use and cooling, they can last for hundreds of holes. Lifespan depends on the material, drilling speed, and maintenance.

Lifespan depends on the material, drilling technique, and cooling—quality bits can last for dozens of large holes when used correctly.

It depends on material, speed, and care—properly used, quality bits can last for hundreds of holes.

They’re extremely precise compared to twist drills, producing burr-free holes with tight tolerances and clean edges.

Insert the shank into the chuck, tighten it securely, and ensure the bit is straight before starting.

Match the bit diameter to the anchor or hole needed, ensure it’s carbide tipped, and choose the right shank for your drill.

Rinse in water to remove debris. For heavy buildup, scrub gently with a soft brush.

Use a larger hole saw with the right arbor, or use a hole saw guide to enlarge an existing hole without wandering.

Use a metal-rated hole saw or step bit, slow drill speed, firm pressure, and cutting oil for lubrication.
