Detailed Review
This 21-piece high-speed steel twist drill bit set handles everyday general-purpose drilling across varied workshops and home projects. It provides a wide range of standard fractional diameters designed specifically for boring into metal, hardwood, softwood, PVC, and fiberglass.
The engineering focuses on precision and efficient waste removal. Featuring 135-degree split-point tips, these bits start cutting on contact to prevent the bit from wandering across hard surfaces. A parabolic flute design improves chip ejection in wood and metal, while the 31-degree helix moderates cutting aggression so you can drill deep holes without binding.
For durability, the bits are treated with a black oxide coating that helps resist corrosion and extends working life under regular use. In terms of trade-offs, the set is explicitly intended for general materials like wood, plastics, and metal, so it is not listed for masonry or concrete tasks. The listing also does not mention whether a storage case or index is included to organize the 21 pieces.
Verdict: This set is a solid choice for DIYers and tradespeople who need a dependable collection of bits for wood, plastic, and metalwork. It delivers reliable starting accuracy and smooth chip clearing across deep-hole tasks.

FAQ
What materials can these drill bits cut through?
They are designed for drilling into metal, hardwood, softwood, PVC, and fiberglass.
What is the benefit of the 135-degree split-point tip?
The 135-degree split point begins drilling immediately on contact and stops the bit from walking across hard work surfaces.
Which bit sizes come with duplicates in this 21-pack?
The set includes two of each for the 1/16-inch, 5/64-inch, 1/8-inch, 3/16-inch, and 1/4-inch sizes, alongside single units of the other listed dimensions up to 1/2-inch.
