About Drill Bits

Drill Not Included

Drill precise holes without a drill press. Simply attach the chuck on your hand-held drill to the drill guide's 5/16” round connection shaft. A dual-locking knob and handle with an easy-read protractor let you position your drill up to 45° in either direction. Guides have a built-in V-groove that centers round material.

Portable Drill Guides for High-Speed Drilling

Drill Not Included

Connect this guide to your portable drill for increased leverage so you can quickly power through your most difficult drilling jobs. A lightweight alternative to magnetic-base drills, use it when drilling into steel plates, pipes, and I-beams. The guide has a V-groove that centers round material. It comes with two drill clamps that will fit onto most portable drills that have a round collar.

Mini Magnetic Drill Base

Drill Not Included

Get the accuracy of a drill press when you use this lightweight, portable drill base with Milwaukee electric drill models 0234-6 and 0244-1. The powerful electromagnetic base firmly attaches to flat, ferrous surfaces such as steel and cast iron. Holding force (also called drill-point breakaway) is calculated against a 1" thick steel plate.

Hex-Shank Drill Bits with Guide for Countersunk Holes

The built-in guide has a beveled tip that fits into countersunk holes in hardware, such as hinges and latches, to center the bit. Guides are spring loaded; drilling pressure compresses the guide body and extends the drill bit into the workpiece. Insert directly into power screwdrivers, impact drivers, and other tools that accept a 1/4" hex shank. Also known as Vix bits.
