If you need to recess a large bolt when building a deck or other outdoor project, it’s usually a two-step process. This is okay if you only have to hide a few bolts, but if you have to recess a ton of bolts it’d be easier to slide Makita’s counter bore over one of their industrial ship auger bits and do it in one step.

Slip the counter bore over an auger bit with a 5/8″ diameter shaft, tighten the set screw, and you’re set to hog out a 2-1/2″ hole for recessing the bolt in addition to the through-hole. You can pay anywhere between $45 and $80 for Makita’s slip-on counter bore.

Forstner bits are awesome. After discovering them for myself, I use my set every chance I get. Even the less-expensive bits leave smooth bore holes with almost no splintering. If you’re a serious woodworker you might want to take a look at some of the finer bits on the market: Bormax Forstner style bits from German manufacturer FAMAG.

The patented design is formed by razor-sharp teeth set in a “wave-form” pattern. It produces less friction and heat, requires less power, and wears slower than other Forstner-style bits. The “wave-form” pattern also clears dust and chips efficiently, producing tear-free and accurate holes. You can use the bits in wood, MDF, plywood, and plastic.

Precision machined from high carbon steel, the imperial sized bits either have a 5/16″ or 3/8″ shank and they’re sold in sizes from 5/8 to 2-1/4″. You’re going to shell out anywhere from $20 to $75 for a single Bormax bit depending on the size. To save some money, you can purchase kits with either 5 or 16 bits for $140 or $530, respectively.

Rather than have a set of counter sink bits that may not be the exact size you need, you could replace them with one adjustable countersink boring bit. Amana’s Di-Count fits over drill bits sized 3/32″ to 9/32″ to drill counter sunk holes for wood screws sized #2 to #18.

The 2-wing carbide-tipped bit will countersink screws up to 7/16″ deep. The countersink bit measures 1-1/4″ long and uses two screws to clamp around the pilot bit. Before shipping charges take a bite out of your wallet, you’ll pay about $23 for the Di-Count adjustable countersink boring bit.
