Slow speed with steady pressure—fast speeds overheat and dull the teeth.

No. Wood drills best dry; lubrication is for metal or masonry.

Only for certain materials and bits. For hole saws, use a regular drill for better control and cleaner cuts.

Yes. Lubricants like cutting oil reduce heat and friction, extending bit life.

They cut large-diameter holes in metal efficiently, removing only the material at the hole’s perimeter, which reduces cutting time and effort.

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

They’re heavy-duty drill bits with a tungsten carbide tip designed to handle tough materials like concrete, brick, and stone, providing longer life and faster drilling than standard steel bits.

Drilling through glass, ceramic, porcelain, tile, granite, marble, and other hard, brittle materials.

Drill bits with an extended flute and shank length designed to reach deep or hard-to-access areas while maintaining hole accuracy.

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