Before you believe a bad review about us

We would like to respond openly to every negative review about us. Many are posted anonymously, so we cannot reach those customers directly. This open letter is our reply, and we would be grateful if you took a moment to read it.

But here is what a one-star review will never tell you:

  • We import from 70+ official distributors. That is why you pay far less than local retail — and why delivery takes longer. We publish the date before you pay, never after.
  • You can pay only when your goods land in Johannesburg. Pay on Arrival, no full payment up front. Ask yourself what scammer offers that.
  • Nobody has ever lost money with us. You get the product, or you get a refund. There is no third option, and there never has been.
  • We are part of the ITwork group — ten years trading in Europe, nine stores, thousands of positive reviews.
  • Johannesburg and Cape Town stores open this year — real shelves, real stock, walk in and buy the same day.

We are not satisfied with our review scores, and we are not going to fix them by hiding anything. We are fixing them by being faster, clearer and easier to reach than any reason to complain.

Read the full letter — photos and video of real shipments, and a straight answer to every accusation.

The RUKO SPB-DIN338 4.4mm HSS-Co twist drill bit is built for demanding drilling in hard materials where standard HSS bits fail. Its 5% cobalt alloy and fully ground flutes deliver high heat resistance and precise holes in stainless and acid-resistant steels.

Highlights

  • DIN 338 twist drill bit with 4.4 mm diameter
  • HSS-Co (5% cobalt) for high hardness and wear resistance
  • 135° split point for self-centering and reduced walking
  • Right-hand cutting, cylindrical shank, tolerance h8
  • Bright bronze-tinted finish for chip flow and corrosion resistance

In daily use

Ideal for professional and industrial drilling in stainless steel, alloyed steel, cast iron, and non-ferrous metals up to 1100 N/mm². The split point starts on contact without a center punch, while the fully ground flutes clear chips efficiently for fast, accurate holes.
