Silverline Titanium-Coated HSS Step Drill - 4 - 30mm

It is very efficient for drilling holes in drywall frames above or below to let electric cables through.

Hello; Product meets my expectations, very effective with aluminum, work impeccable!

Excellent cutter allowing a large diameter to be drilled cleanly without reaching the rear wall. (case of cleaning intervention on 50mm PVC evacuation pipe).

I purchased it to make grooves in a stainless steel tube. I am very satisfied with the results.

After several uses, the product is effective in materials such as pvc, plexiglass or thin metal sheets. The cut is very clean. However, pay attention to the speed of rotation because the cutter can very quickly engage in the cut at the larger diameter! Tip to avoid this: attach a pvc collar type cerflex to the diameter not to exceed. The strawberry will not be able to engage beyond!

practical for cutting in the plastic, to see in the metal
