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
