T-Handle Tap Wrenches

Use with a tap to thread holes by hand. These wrenches are more compact than straight-handle tap wrenches, so they can be used to tap in tighter spaces. However, they provide less leverage.

Tap Wrenches

Sliding Ratcheting Handle—Sliding ratcheting handle moves from side to side and can lock in a fixed position. It adjusts for right- or left-hand ratcheting.

Machine-Mount Tap Wrenches

Machine-mount wrenches have a guide shank that fits into the chuck on your drill press and holds the tap steady. Use them after drilling to thread holes manually without moving the workpiece.

Sliding Handle—Sliding handle moves from side to side to allow tapping in spaces where fixed handles don't have room to turn.

Air-Powered Tap Wrenches

Powered by compressed air, these tap wrenches thread holes faster and with less effort than manual tap wrenches. They’re often used in place of manual tap wrenches when threading many holes and hard materials. Compared to drill presses and CNC machines, which are stationary, these wrenches are portable so you can take them to the part that needs to be threaded. To remove chips from your hole, press the reverse button to rotate the tap counterclockwise. Switch different taps in and out of the chuck when your tap is worn down or you need a new size. Use with machine tool taps and tapping lubricants for best results.
