If your Dad has the basic collection of tools for use around the house, he may believe that what he has will serve him well and, like most Dads, think that he doesn't need any power tool or gadget upgrades. All the better to give him a treat this Fathers Day, and surprise him with the newer versions of craft tools that will make his hobby or work tasks a lot easier.
For example, this from Dewalt -- their 20 Volt Combo Kit (was $279; on sale now from Amazon for $242. Click through to Amazon to get the deal). You get a lightweight -- easy to handle in confined spaces -- 1/2" drill that sports a two-speed transmission for a wide range of working speeds, with a delayed-off LED light source. Add to that the 1/4" impact driver -- 53 impacts per second -- with one-hand loading. Also included are a pair of quick-charging lithium batteries, a charger, a pair of belt hooks, and a carry bag. Nice.
One of my personal favorites, the Dremel 4000 120 Volt Variable Speed Rotary Tool (regularly $260; now on sale at Amazon for $132. Click through to Amazon to get the deal). I love the handling characteristics of this engraving/cutting/polishing tool; rotation speeds vary from 5000 to 35000 rpm to accomplish any job around the house or shop; it arrives with a variety of 50 accessories and it will accommodate all the available Dremel tools. Five year (limited) warranty on this fine tool for Dads Day.
For a hands-free approach to lighting the nooks and crannies around the house, this 3 Watt Cree LED Headlamp (was $50; now on sale at $32). This little jewel of a headlamp uses three AAA batteries, for a max of four hours continuous illumination. Weighing in at a featherweight five ounces, and with an adjustable headband, this 10,000 hour lamp is sealed against moisture by an O-ring.
