Buying Guide

Smooth cuts. Easy use.
You will love the fast, clean holes.

Engaging experience
When the bit meets the material, it feels like a gentle glide. The result is a perfect, flush screw head every time.

Factors to consider

Material of the bit
Choose high‑speed steel (HSS) for durability. Cobalt or TiAlN coatings add extra wear resistance.
Cutting angle
82° works well for most wood and metal screws. 90° gives a deeper chamfer for larger fasteners.
Flute count
5‑flute bits reduce vibration. 6‑flute bits clear chips faster.
Shank size
A 1/4‑inch shank fits most drills. Larger shanks give more rigidity for big holes.
Length of the bit
Short bits are stiff and easy to control. Long bits reach deeper countersinks.
Finish
Black oxide or gold coating protects against rust. A plain HSS finish is fine for occasional use.
Size range
A set that includes 1/4″, 3/8″, 1/2″, 5/8″, and 3/4″ covers most projects.
Case or storage
A plastic or aluminum case keeps bits organized and protected.
Price vs. performance
Spend a bit more for coated bits if you work often. Basic HSS sets are cheap and work well for light jobs.
Compatibility
Make sure the bit fits your hand drill or magnetic drill. Check the shank type (round or Weldon).

Quick tip
After each use, wipe the bit and apply a drop of oil. This stops rust and keeps the edge sharp.
