Industrial Wood Drill Bits
Brad Point (Dowel) Bits for Wood
These are one of the three main types of wood drill bits, characterized by the small point at the tip. Spurs on either side of the point will cut clean, straight holes.

Industrial Auger Drill Bits HSS 6542 Black & Gold Finishing Twist Drill Bit Roll Forged DIN338
Auger Drill Bits
These cut large, deep accurate holes. The spiraling shaft comes to a fine, threaded point. Carbon-steel bits are best and can be resharpened.

Industrial Wood Drill Bits
Wood Spade or Paddle Bits
The pointed tip begins the hole and the paddle-shaped blade bores large, wide holes. The size is clearly marked on the paddle’s face.

Industrial Metal Drill Bits
Metal Drill Bits
These are known as high-speed steel (HSS) bits and are characterized by their black color. More expensive, durable ones may contain cobalt or be titanium-coated. They can also be used on wood or plastic, but they last longer if reserved for metalwork.

Industrial Masonry Drill Bits M35 Cobalt Straight Shank Drill Bit HSS DIN338 For Stainless Steel Drilling
Masonry Drill Bits
These can cut into many masonry surfaces. The shaft spirals up to a tip that is often composed of an extra-hardened material. Bit colors vary because of the different materials used. The tip may be a different color from the shaft due to a hardened coating. For instance, a chrome-vanadium shaft may be finished with a tungsten-carbide tip.

Industrial SDS Drill Bits
SDS Bits
In addition to the standard drill bits, there is a wide range of specialty bits are available made for a specific task, or to fit a particular type of chuck. These are made specifically to fit an SDS chuck mechanism, and won’t work with any other. The end that fits into the chuck has a fluted appearance; the drilling part of the shaft is normal. DIN338 AND ANSI Standard Straight Shank Surface Finish Drill Bits
