with titanium coated contact points
TiN-coated measuring contact points(over 6mm/.275" range models) provide excellent durability and impact resistance and allow the instrument to measure right to the bottom of a blind hole. 
Highly durable because of carbide-tipped contact points (anvils). 
Measurement can be taken closer to the bottom of the blind bore. 
Can measure deep holes using an Extension rod (optional) which is available on models over 6mm (.275") measuring range. 
With Ratchet Stop for constant force
