Product Description:
GEARWRENCH has taken the ratcheting wrench design and applied it to the tap and die application. The ratcheting handles and adapters allow for easy back and forth movement required while cutting threads on either taps or dies. The 5° ratcheting arc with reversing lever eliminates hand over hand turning. The hex die adapters work on either round or hex shaped dies. 

• Die adapter works on round and hex shaped dies.
• Ratcheting T-handles wind dies with a 5° swing arc and have a reversing lever to eliminate hand-over-hand turning
• Twist Lock guide system reduces the “walk back” of the die guide and keeps the dies centered while cutting
