Baucor: Your Potential Partner in Screw Machine Length Drill Manufacturing
Understanding the manufacturing process gives you insights into the potential for quality and customization with screw machine length drills. Here's why consulting us can be beneficial:
Custom Solutions: If your application demands a unique design or specialized material, Baucor manufactures custom screw machine length drills tailored to your exact needs.
A straight flute drill is a type of drill bit characterized by its straight cutting edges (flutes) that run parallel to the drill's axis. This design is particularly well-suited for drilling materials that produce short chips.
Stub length drill bits are shorter versions of standard jobber length drills. This design prioritizes rigidity and precision.
Extra long length drill bits, sometimes called "aircraft extension drills" or "long series drills," are specialized tools designed for drilling deeper holes than standard drills can reach.
Taper shank drills are specialized tools designed for heavy-duty drilling applications. They feature a tapered shank that provides a secure, self-tightening fit in compatible machine spindles or tools.
Possible Screw Machine Length Drill Sizes:
Baucor can manufacture drill bits for you ranging from very small sizes like 0.05 mm to large sizes up to 180 mm, accommodating a wide spectrum of drilling requirements. Please contact us for the appropriate dimensions. Baucor can produce drill bits in the most specialized sizes tailored to your needs.
The optimal material for a screw machine length drill bit depends on the specific application and the workpiece material being drilled. Here's a breakdown of possible options, including those for both common and more specialized drilling tasks:
Common Materials:
Specialty Materials:
A drill chamfer tool is a specialized cutting tool designed to streamline the process of creating holes with chamfered edges. It combines the functions of a drill bit and a chamfering tool, eliminating the need for separate tools and operations.
Three flute drill bits are a specialized type of twist drill designed for specific applications.
A Forstner drill bit is a specialized type of drill bit designed to create clean, flat-bottomed holes in wood. Unlike typical twist drill bits, Forstner bits utilize a circular cutting rim for a smooth finish and exceptional precision.
Una punta per trapano per vetro/piastrelle è una punta specializzata progettata per tagliare materiali duri e fragili come vetro, piastrelle di ceramica, porcellana e marmo.
Due to their shorter length and increased rigidity, screw machine length drill bits find use in various scenarios where standard length drills might not be optimal. Here are some common areas where they are used:
Precision Drilling:
Manufacturing and Production:
Additional Applications
When Standard Drills Might Be Better Suited:
In applications where deeper hole drilling is required, standard jobber length drills or longer aircraft drills would be necessary.

Baucor: Your Partner for Drilling Solutions
While the machines listed above are the most common to use with screw machine length drills, understanding your project needs is key. Here's how partnering with us can ensure you have the right tools for the job:
Reduced shank drills, also known as blacksmith's drills or silver and deming drills, are specialized tools designed to provide flexibility when working with different drill chucks or machine spindles.
An auger drill bit is a spiral-shaped drill bit designed for boring holes into wood, soil, and sometimes even ice. Its design resembles a large screw, making it highly efficient at clearing out chips and debris as it drills.
A spade bit is a flat, paddle-shaped drill bit designed for boring large holes in wood. It features a sharp center point for precise positioning and two broad cutting edges for rapid material removal.
Spot drills are specialized cutting tools designed to create a precise conical indentation ("center") in a workpiece. This serves as a highly accurate starting point for subsequent drilling operations, ensuring the drill bit doesn't wander and ensuring proper alignment.
At Baucor, we believe that even screw machine length drills can be optimized for exceptional performance. We go beyond simply offering standard options, focusing on design and engineering excellence to ensure you have the perfect drill tailored to your specific needs.

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.
