le foret et trop petit le truc est inutilisable

The pilot drill is too short, so I was not able to use the core drill without an additional pilot drill.

This core bit is not useable due to the pilot bit not being long enough to lead the bit. Bit will not cut masonry.

The pilot drill is shorter than the core drill making the entire thing completely useless misleading not as shown in the picture

The core drill bit failed after one hole. The weld failed. I have picture but cannot get it sent to you.

You may be thinking of purchasing this as a cheaper option, but it's not worth it. The bit didn't drill even 1/4" deep before the threads on the arbor broke, the threads on the pilot set screw broke, the pilot bit is way too short. The metal is too soft for the use it is supposedly designed for. Terrible quality, I couldn't even drill out one hole.

The core bit was good prices and delivered quick but the pilot bit was shorter than the outside core making it impossible to start the hole. I had to grind down an existing sds bit to make it fit so I could get the job done. Very dissapointing.

Never received drill bit

produit visuelemnt de bonne qualité, le soucis c'est que le foret centreur est plus court que la carotte,, tu as interré de bien tenir ton perfo pour faire mordre dans le beton,,

A waste of my time and money. Pilot bit shorter than the core bit, no way to keep the core bit from walking to get the hole started. Vevor hasn't let me down before but this was ridiculous.
