Features:

• Self feed: This permits the tap to act as its own lead screw, allowing even inexperienced operators to produce gage perfect threads. Thread depth repeatability can be maintained accurately.
• Pre-selective torque drive: A spring loaded ball-detent clutch is completely adjustable for material and tap size, to prevent tap breakage. The clutch is impervious to oil or grease contamination and maintains consistent torque repeatability through highest production runs. The clutch design is intended as a safety device only, and a machine stop should be set to allow the tap to release in neutral before bottoming whenever possible.
• 1.75 x 1 reverse ratio: Permits the tap to retract from tapped hole 75 percent faster than it entered, which greatly increases production. Right or left hand tapping without modification.
• Re-entry cushion: A cushioned drive eliminates cross threading. It is possible to re-enter the same hole as many times as necessary and still maintain a gage perfect thread.
