Description of Foredom H 18 Quick Change Handpiece
he H.18 is for use with only 2.35mm (3/32") shank burs. It features a very slim grip and pre-lubricated ball bearings. 7" long, 19/32" dia. Member of the Foredom system of "Interchangeable Handpieces".
I have another fake quick change handpiece and then this one. The off-brand brand has worked well for two years in heavy use this tip was used in light service for about 5 months before one of the bearings failed (out of warranty) not sure if there is a reason to buy an accessory. with her name on it again.
Pros
H.18 is only for use with 3/32" (2.35mm) shank drill bits
