Step drill bits are significant for drilling pilot holes because they can create a hole of any size that you need. Here are the top 10 uses for step drill bits 1. For this reason, they are typically only used for drilling holes in softer materials such as wood or plastic. Step drill bits also wear out more quickly than other drill bits due to the spiral flutes cutting into the material as they rotate. This is not a problem, but if a precise spot is required, another type of drill bit should be used.
One downside is that they tend to create a slightly ragged hole, with the bottom slightly larger than the top. While step drill bits are convenient, they are not suitable for all applications. Step drill bits are available in various sizes, and the number and spacing of the steps will vary depending on the size of the bit. The steps are typically spaced about 1/8 inch apart so that the gap can be enlarged in small increments. The most common type of step drill bit has two or three different-sized steps, each of which can be used to create a different diameter hole. Step drill bits are also sometimes used to create countersinks for screw heads.
They are commonly used in applications where precise hole size is not critical, such as when hanging pictures or installing shelf brackets. Step drill bits are versatile and can be used for various tasks, such as drilling pilot holes for screws or enlarging existing holes. The flutes also remove chips from the hole as it is drilled. The bit consists of a cylindrical shank with spiral flutes that cut into the material as the bit is rotated.

They excel at drilling thinner and hardened metals.Ģ9 pc set includes bits from 1/16”-1/2” by 64ths and comes in a strong, lightweight, high-density plastic case that is weatherproof, waterproof and unbreakable. They are recommended for use with cast iron, brass, sheet metal, plastic, aluminum, mild steel, copper, hardened steel and even wood and composites. The three-flatted shanks reduce slippage common with keyless chucks. Bits larger than 1/2" have 1/2" shanks with 3 flats Plus, these bits virtually eliminate burrs and blowout on the exit side. They are perfect for enlarging existing holes without binding or grabbing as the bit exits the material. The 135° split point allows for fast penetration, accurate and easy starting without a center punch. The precision ground point, flutes, body, clearance and drill diameter result in the ultimate in accuracy and performance. This unique tip geometry requires less torque which creates less heat and thus increases tool life.Ĭonstructed from special Hi-Molybdenum tool steel these bits stay sharp up to 4X longer than conventional and other specialty drill bit designs. and allows for laser straight holes in metal and other materials. These Vortex-Point drill bits cut 45% faster than conventional split point drill bits. The multi-stepped tip acts like a step drill which prevents walking on curved surfaces.
