Hand Reamers
HSS Hand Reamers with Left Hand Spiral (right hand cutting).
Hand reamers are turned in the hole by means of a tap wrench which is mounted on the square. The feeding action is produced manually. To ensure a proper guidance a hand reamer taper lead length is made longer than a Machine Reamer.
For best results reaming by hand: Turn the tool only in the cutting direction - NEVER reverse the tool - cutting edges will become immediately blunt if the reamer is turned back.
