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.

This step drill bit delivers a 4–20 mm drilling diameter range across 9 precisely ground steps, each incrementing by 2 mm, making it a versatile choice for clean, burr-free holes in sheet metal, non-ferrous metals, plastics, and wood up to 4 mm thick.

Overview

The kwb 524010 is a high-speed steel (HSS) step drill bit with a titanium nitride (TiN) coating for enhanced wear resistance and reduced friction.

What stands out

  • 9 steps from 4 mm to 20 mm in 2 mm increments
  • TiN coating for longer life and smoother cutting
  • Cross-ground tip for precise centering
  • Deburrs and chamfers as it drills
  • 8 mm cylindrical shank fits standard drill chucks
