Screw Machine Length (SML) Drill Bits are designed for specific applications and have unique design characteristics compared to standard twist drills. Here are the key design guides for SML drill bits:

Shorter Overall Length: SML drill bits have a shorter overall length than standard jobber length drill bits. This shorter length increases rigidity, reducing deflection and vibration during drilling, especially in high-speed machining operations like those performed on screw machines.

Thicker Web: The web of an SML drill bit, the central portion between the flutes, is often thicker than that of standard drill bits. This added thickness provides more strength and durability, which is important for the high-speed and repetitive drilling tasks SML bits are typically used for.

Stronger Point: SML drill bits generally have a stronger point design, such as a split point or a self-centering point. This helps to improve drilling accuracy, reduce wandering, and prevent work hardening of the material being drilled.

Flute Geometry: The flute geometry of SML drill bits is optimized for efficient chip evacuation, ensuring that chips are removed quickly and effectively during drilling. This helps to prevent chip buildup, which can cause heat buildup and damage the drill bit or workpiece.

Material Selection: SML drill bits are typically made from high-speed steel (HSS) or cobalt steel, materials known for their hardness, wear resistance, and ability to withstand high temperatures. Some SML bits may also be coated with titanium nitride (TiN) or other coatings to further enhance their performance and longevity.

Common Applications: SML drill bits are primarily designed for use in screw machines, where they are used for high-speed, repetitive drilling operations. They are also used in other applications where a shorter, more rigid drill bit is preferred, such as drilling in confined spaces or when working with harder materials.
