Editor's Notes

June 26, 2019:

When you’re boring holes into wood, an auger drill bit is often necessary for the job. This centuries-old tool has sharp spurs on the edges of its tip to make sure the hole it’s creating is smooth and uniform throughout. Its fluted design allows for the removal of debris as you work, and it keeps the new hole from becoming clogged with shavings. Most auger bits are intended only for use with wood, although there are exceptions (such as the Yard Butler on our list, which is made to create holes in soil). These tools are well suited for projects like making furniture, constructing a backyard deck or raised garden bed, and more.

Joining our list is the DeWalt DW1681, which is made with an overall length of 17 inches, with a 5/8-inch diameter. It’s built for the long haul, with a hardened alloy steel body and a sturdy, dual-cutting edge. Its self-feed spur quickly penetrates through all types of wood, and the hollow center flute assists with debris extraction. And, you’ll appreciate the convenience afforded by its handy ball groove end that allows you to remove it easily from your drill chuck when you’re done using it.

Another new addition is the sturdy Milwaukee 3-Piece Set, which will help you drill with confidence into any wooden workpiece. These shiny tools come in three commonly used diameters and feature a polished flute finish to which shavings won’t stick. The longer shaft length makes it simple to drill deep without needing an extension. And the signature Milwaukee-red, roll-up pouch certainly comes in handy for organization and portability.

Sadly, the Pit Bull CHIAU0624 eight-bit set leaves the list in his update, due to its lack of availability. Also making an exit is the TruePower 09-0279 Stubby, due to some reported quality issues.

No matter which tool or set you choose, always be sure to follow safe woodworking practices, including protecting your eyes and ears and unplugging power tools when you’re making adjustments to them or swapping out bits.
