Clamp-On Drill Guides

Drill precise holes without building a fixture. Clamp the jig onto your material and lift and turn the turret to select the hole size you need. Use the graduations to set the jig to the centerline of your workpiece.

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.

Wrenches with aligner square your tap to your work surface for proper alignment and reduced tap breakage. A V-groove at the base provides stability on round surfaces.

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

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 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.

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.

Economy Straight-Handle Tap Wrenches

For occasional or light-duty hand tapping, connect a tap to these wrenches. They have long handles to provide more leverage than T-handle wrenches, but they require more space for tapping.
