BeHappy 29Pcs Cobalt Drill Bit Set 135 Degree Tip - Durable HSS Kit

In this review of the BeHappy 29Pcs Cobalt Drill Bit Set, the bottom line is simple: this kit is aimed at DIYers and tradespeople who want a broad range of durable bits for drilling into metal, wood and plastic. The most compelling reason to buy is the combination of HSS cobalt construction and a 135 degree split point tip that reduces walking and speeds penetration, making routine drilling tasks feel more controlled and efficient. The included metal indexed case also keeps the full size range organized for workshop use.

Key Features

• Complete size range: Includes 29 sizes from 1/16in to 1/2in so the user rarely needs another set for common projects.
• HSS cobalt build: High speed steel with cobalt improves cutting performance and helps when drilling harder metals.
• 135 degree split point: Self-centring tips reduce thrust and prevent bit walking for more accurate starts.
• Black and gold oxide finish: Finish increases corrosion resistance and reduces wear for longer life.
• Hardened and polished tips: Professional hardening and polishing aid sharper edges and faster chip removal.

Who It's For

This set suits weekend DIYers, hobbyists and professionals who need a versatile collection of jobber-style drill bits for general purpose work on stainless steel, mild steel, wood and plastic. The broad size selection is convenient for repair work, metal fabrication and carpentry where a single kit should cover most hole sizes.

Those who frequently drill very hard alloys or require cobalt bits for heavy industrial continuous production might prefer a dedicated industrial-grade series with metric sizes or individually sourced premium bits. If you need metric-only sizes, this inch-based set is not ideal.

Pros & Cons

Pros

• Wide 29-piece size range provides solutions for many projects without buying extra bits.
• Sharp tips and 135 split point make starts easier and improve drilling speed.
• Durable black and gold finish helps resist corrosion and extends usable life.

Cons

• Quality feedback is mixed; while many users report good value and sharpness, some consider the overall quality inconsistent compared with premium brands.
