Steinless steel H-files are very effective and invasive
The H-file has a great cutting ability and it is designed in a shape proposed by Dr. Hedström. The Hedström file is designed to be used with longitudinal filing and rotary cutting (up to 1/4 turn) actions. It is particularly recommended in pediatric dentistry.
Great cutting ability
One cutting edge angled at 90 °
Extraction of dentin debris improved by increasing feed of cutting edge
Very good flexibility greater than stainless steel instruments
