Impact drill bits are durable bits used in high torque applications. These drill sets contain bits that are specially designed for drilling holes in glass and tile. These drill bits have three flat sections ground into the shank, which helps to keep the bit from slipping in the drill chuck. These shanks assist in precise centering. StraightĪ straight shank refers to a bit with a shaft and shank of the same diameter. Its main benefit is consistency in drill bit centering. The round shank bit is common in the metalworking industry. It is a straight shank that has a reduced size in comparison to the drill diameter.
ReducedĪ reduced shank is used when the drill diameter is larger than what can be held in the chuck. They can be used with rotating tools such as drills and drill presses. Hex shanks have flat surfaces on the shank allowing for high torque transmission. The 3 flats shank allows for a higher torque and limited slipping. SpearĪ spear point allows you to increase your cutting speed because it reduces the overall cutting pressure being applied. A split point is used to keep the bit centered without a pilot hole. The blunt point angles of drill bits between 130° and 150° produce smaller chips and can be used for harder and stronger materials.
The split point is used to keep the bit centered without a pilot hole. 118° SplitĪ 118° point angle is considered a smaller point angle and is ideal for drilling softer materials such as aluminum alloys. Point TypeĪ 118° point angle is considered a smaller point angle and is ideal for drilling softer materials such as aluminum alloys. These tool bits may be treated with coatings to enhance tool life and strength and are suitable for use with most materials. High speed steel (HSS) is preferred over other carbon steels due to its heat resistance in high speed drilling applications. It is used on stainless steel and other hard materials. CobaltĪ main benefit of cobalt is its ability to maintain sharpness in high temperatures. Uses include drilling cast iron, nonferrous materials, wood and abrasive compounds such as plastics and fiberglass. MaterialĬarbide drill bits are stronger, and their cutting edges last longer than cobalt bits. Straw oxide finishes are added to reduce the grinding stress caused to the tool. Titanium bits last significantly longer than high speed steel and are heat resistant, leading to increased tool life.
GoldĪ gold finish provides wear resistance and lubricity. They may be used to work plastics, woods, or metals.
Brightīright finish refers to the surface of drill bits which lack coatings that extend tool life and improve cutting performance. They are intended for use with ferrous metals. Black Oxideīlack oxide finishes resist damage from heat and corrosion, leading to a longer tool life.
