• ANGLE DRILL BIT DRIVER

This allows the spade to cut a wider, bigger, more accurate hole in wood pieces.Īdjustable Wood Bit: This is similar to a spade bit, but the spade part at the end of the tool is adjustable. It features a long shaft, at the end of which is a flat, pointed spade. Spade Bit: The spade bit looks much different from twist and twist-like bits. The brad point bit is usually used for drilling wood. This added accuracy is coupled with flaps on the threads which remove and clear chips. It can be used to remove pre-drilled standard screws, or in situations where left-handed drilling is much easier due to the nature of an application.īrad Point Bit: Similar to a twist bit, the brad point bit has brads for positioning and cutting purposes. Left-Hand Bit: This is a bit that runs counterclockwise. Their tips are usually flat as they never need to start holes, only enlarge them. The design of the helical groove is such that the shaft can have strong structural integrity, while the fluted groove drives chips upwards.Ĭore Drill Bit: This bit is used primarily on pre-drilled holes, and is used to make them bigger without disrupting their structural integrity. The center bit is easy for hand use because the torque alone can draw the bit deeper in to the wood, but electric versions are also available.Īuger Bit: Similar to a center drill bit, the auger bit is primarily focused on moving swarf and chips out of its way.

Directly behind the screw thread is a radial spur which increases the size of the hole. The external method flushes chips out in the standard format.Ĭenter Drill: The center drill bit has a tapered screw thread as a tip, used for drilling holes into wood. The internal method has a hollow area running through the main cylindrical section, and the coolant flushes out the chips. The function of both is the same, as it filters coolant into the hole being drilled while flushing out the swarf and chips created by the drilling process. Gun Drill: A more complicated bit, the gun drill is available in two basic set ups, internal and external. Twist bits can be long, wide and feature different thread angles to ensure faster drilling or prevent breakage in different courser, stronger materials, such as steel. In addition to its originary status, the twist bit is also one of the more common drill bits as it can function on metal, wood and plastic. Its name is descriptive, as the bit is simply a long cylinder of metal with grooves on opposite sides which has been twisted to form a screw-type shape. Twist Bit: The oldest type of bit, the twist bit was invented in 1863 by Steven Morse. As the options for drill bits for a given application can be daunting, it is helpful to look into the different bit specifications and configurations before choosing the proper bit for the job. Drill bits can be used on wood, metal, plastic or, in same cases, porcelain, and due to the broad ranger of drill bit configurations available, they can make a variety of holes for many different applications and purposes.
