1/2" Diameter Reduced-Shank Drill Bits
The shank has a smaller diameter than the tip, allowing you to drill large holes with machines that have small-capacity chucks. Also known as Silver and Deming bits, they have a 1/2” diameter shank.
Drill bits with flats on shank have three flat sides to prevent the bit from slipping in the drill chuck.

Round- and Hex-Shank Masonry Drill Bits for Rotary-Only Drilling
Instead of using a hammering action to break up masonry material, these bits drill with rotary action only, requiring more pressure to grind up material. Use with handheld power drills, drill presses, and in hammer drills set to rotary-only mode. Do not use in hammering applications.
When using bits with a maximum drilling depth of 10 1/2” or greater, take the bit out of the hole every 4” and remove debris before drilling deeper to achieve maximum drilling depth.

Smooth-Finish Drill Bits for Wood
Bore clean, flat bottom holes in soft wood, veneer, and laminates. The center guide point prevents the bit from wandering. Also known as Forstner bits.
Carbide-tipped steel drill bits maintain their sharp edges longer than alloy tool steel bits, and can cut through tough, abrasive material such as plywood, hard wood, and composites.

Fast-Cutting Smooth-Finish Drill Bits for Wood
Multiple outlining teeth bore clean, flat-bottom holes without chipping or splintering your surface—even when cutting across the grain. These bits are excellent for boring straight holes, overlapping holes, and holes on close centers in soft wood, veneer, and laminates. The center guide point prevents the bit from wandering. Also known as multispur bits or Forstner bits.

Replaceable Carbide-Insert Drill Bits
Use these bits to drill a large number of holes with high precision. When the cutting edges dull, replace the carbide inserts (sold separately) instead of the entire bit. Each drill bit requires two inserts—one on the inner cutting edge and one on the outer cutting edge. Bits can be used in CNC machines with coolant-through technology; holes in the bit allow coolant to be channeled through the tool for more efficient chip evacuation.
