Description of DEWALT 21 Pack Black Oxide Twist

DEWALT 21-pack black oxide twist drill bit set is ideal for general-purpose drilling materials like metal, hardwood, softwood, PVC and fiberglass. Parabolic flute design increases chip ejection in metal and wood drilling applications. Black oxide coating helps resist corrosion and increase durability, so your drill bits last longer. 135° Split-point tips drill on contact and prevents walking on the hard surface you’re working on. 31° Helix reduces over aggressiveness of true parabolic flute, making it ideal for drilling deep holes.

DEWALT 21 This is a serious metal kit - all pros and cons about this

Greetings to all! Today I want to share with you my impressions of the "one-on-one" use of a set of metal drills from DeWalt. The kit includes 6 drills with diameters of 2.3, 4.5, 6 and 8 mm.

Pros
  • Long kilometers, quickly cut metal and wood
Cons
  • Price

DEWALT 21 Drills that drill: my truth review

I bought such a set of drills in Castorama. 1100 rubles for 10 drills. Moreover, next to the set, the same drills were sold separately. A 10mm drill, for example, cost 400 rubles. So the benefit of buying the whole set was obvious. The transparent lid of the set is very flimsy, but hasn't broken yet. Although, even if it breaks, nothing will fall out anywhere. Drills 1-5 mm are quite ordinary in appearance. Except for the gold oxide coating that protects the drill from overheating. But even…

Pros
  • Drilling speed, set price
Cons
