### ⭐⭐⭐⭐⭐ Excellent piece of kit
*by F***K on 31 July 2025*

It was quite good for the short time it lasted The hex shank broke off on the light duty work enlarging a hole from 6 to 8 mm on a light fitting update the seller has told me he will replace to step drill

### ⭐⭐⭐⭐⭐ Works
*by B***Y on 3 October 2025*

Excellent piece of kit sharp and clears swarf down the four flutes

### ⭐⭐⭐⭐ Very sharp and easily drilled into stainless steel
*by D***R on 26 April 2024*

Easily drilled into tough materials, including stainless, leaving a very clean hole. No sign of blunting after drilling about 30 20mm holes, but I haven't used it for long enough to know how well it will keep its sharpness.
