HKM Bit Guard 85 cm Diameter Black

They are super stiff. I had to put them on the bit with a work band and clamp, so with a lot of force. This says something about the good and sturdy quality. I've been using them for 3 months now and they still look new

• Good quality

• Hard to get the bit

A product that could have been good. However, the washers are not flexible: you can't fit them on the bit.

• Good and cheap

• Not flexible
• Rigid

These bit rings… a real frustration to attach but they have many benefits. They don't smell at all, are mega sturdy, smooth and well finished. I put them in boiling water, pulled them apart one by one with two straws and attached them to my bit with someone else's help. I don't think they will ever come back :)

• Good quality
• Good and cheap

• My goodness those things are stubborn
• Hard to get the bit

Top bit rings Good quality and good value for money I recommend +++

• Good and cheap

• Good quality
• Easy to get around the bit
• Easy to clean
