Stanleys ID07 Impact Drill/Wrench embodies the latest product improvements in this tool. Delivering impact torque of up to 500 ft. lbs. (675 Nm), the ID07 is capable of breaking loose some of the toughest bolts and nuts. The ID07 can drive wood augers into the hardest salt-cured or creosote-treated poles. The ID07 has the work-site proven swing-hammer mechanism that will deliver high performance and long-term service. The integral Stanley Hyrevz gear motor is manufactured to exacting standards to deliver maximum efficiency. Available in 7/16-inch hex quick-change chuck or -inch square drive. The quick-change chuck has three large detent balls to positively retain the 7/16-inch hex shanks. The rib on the chuck sleeve makes it easy to push-to-release, even with gloved hands. The new over-sized reversing spool is protected by heavy-duty wiper seals. These wiper seals clean away dirt as the spool is moved. Dirt cannot get in between the spool and housing bore to create leak-causing scratches. A clean spool always runs in the housing; the dirt is left outside. The built-in reverse-check valve prevents operating the wrench when reverse-plumbed to the hydraulic system. Preventing reverse operation ensures a long operating life for the hydraulic seals. Coated with a thick, tough layer of foamed-plastisol, the handle transmits very little heat. The foamed plastisol gives a more comfortable grip to the tool. The forward position of the handle places more of the tool weight on your hand for better balance and control. The cast-in lifting eye is always available, unlike screwed-in lifting rings which may come loose and fall off. The Stanley dual-spool selector is accessible under a seal plug at the rear of the tool. Setting the tool for open or closed-center operation is as simple as opening or closing a valve. The selector is not susceptible to moving under the vibration of use and is completely protected from accidental or unintentional access. The seal plug also protects the end of the trigger spool and dual-spool selector from water and dirt.
