Step Tip Step Drill TiAin

Bordo Step Tip Drill 8-32mm Co5 (Cobalt) TiAlN 3-Flat Round Shank

Used on my aluminium boat

This is one of those tools that makes drilling clean holes in sheet metal way easier.

I use this when working with aluminium and thin materials because instead of swapping drill bits for different sizes, you can step up through sizes with one bit. It cuts clean, doesn’t grab as much, and gives a much better finish than standard drill bits.

Once you use one of these, it’s hard to go back.

What I use it for:

• Drilling clean holes in aluminium sheet

• Enlarging holes without tearing material

• Quick size changes without swapping bits

• General fabrication and workshop use

Details:

• Range: 4–32mm

• Material: HSS Cobalt (Co5)

• Coating: TiAlN

• Shank: 3-flat for secure grip

 Why this one:

Standard drill bits can grab and leave rough holes in thin material. This gives you better control, cleaner cuts, and a more professional finish.

Real workshop tip:

Use steady pressure and let the tool do the work — forcing it will reduce its life and rough up the cut.
