- Light metal
A 14-piece HSS drill set (1/16-1/2 in.) with a titanium-nitride coating, a low-cost all-rounder for wood, plastic, and light-gauge steel. Split-point tips start without skating, and the 3-flat shank resists spinning in a keyless chuck. The TiN coating is only surface-deep, so bits dull fast in metal; they're not for stainless or hardened steel.
Pros
- Cheap, versatile all-rounder that handles wood, plastic and thin metal in one household set
- Split-point tips give no-skate starts and clean holes without a pilot punch
- 3-flat shank on larger bits grips in a keyless chuck and resists spinning
Cons
- The TiN coating is only surface-deep - once it wears off, the bit dulls fast in metal
- Not suited to stainless or hardened steel where a true cobalt bit is needed
- Includes only one of each larger size, so a snapped 1/2 in leaves a gap
