2Krmstr 24Pcs Wooden Beads Drills Bit Knife Set, 6-12mm Carbide Bit Ball Blade Wooden Bead Maker, DIY Wood Ball Woodworking Tools Kit.

These drill bits work decently well on soft wood, but they are not robust enough for hardwoods, and the centering bits break pretty easily. They likely work better on a platform drill where everything can be completely stable and the bit can be kept perfectly centered and wobble-free. If you're using a handheld drill, they still work, but you will run out of centering bits pretty quickly.

This is awsome

Bit as good as advertised. The bits constantly break and had to switch from my 20V battery drill to my older corded drill because the drill is stronger. The bits didn't break as much after the switch. However very disappointed in the product.

When I used the 22 mm one on a 2 x 2 piece of pine it broke the first time I used it, and when I used the 8 mm one on a small 1 x 1 piece of wood all it did was shred the wood. These do not make beads at all. A total waste of money. it is just cheaper to buy beads.

Made very cheap. The drill bits have already broken and only used it a few times. I purchased this so my husband could us it with the students he works with. Unfortunately it will not work.

Horrible, broke the first time we used them and we used soft wood. I should have read the reviews before wasting my money. Very disappointed

Terrible product. ALL of the drill bits provided snapped in half when trying to use! Huge waste of my money.

Broke the first time trying to use them, took forever to receive.
