Q: How do I use it?
Line up the drill bit with your mark and butt the guide against the bit so one of the V-notches flanks it from two sides. The notch stops the bit skating on the surface and holds it at 90° as you start the hole.
15J7401 - Pocket Drilling Guide
Far more useful than its compact one-piece design might suggest, this simple guide block lets you drill holes that are both precisely placed and accurately set at 90° without a drill press.
To use it, just line up the drill bit with your mark and butt the guide up against the bit, flanking the bit from two sides with one of the V-notches in the guide. As you begin to drill, the notch stops the bit from skating on the surface, keeping it centered on your mark. It also ensures that the bit remains held at 90°, much better than even the most steady-handed woodworker can accomplish free hand.
Made of case-hardened O1 tool steel to resist wear from contact with spinning drill bits, the 1 3/4" diameter guide has knurled edges for grip and two notches – one 7/8" tall, and one 1/2" tall for use with shorter bits. You may be surprised how much your drilling accuracy can benefit from less than an inch of bearing surface.
