Atlas Cutting Tools offers a wide varity of High Speed Steel Drills that are sutible to work in materials ranging from Alloyed and non alloyed steel, Soft stainless steel,  Soft cast iron,  Aluminium,  Copper, Brass and Bronze

When it comes to drilling, having the right drill bit for the job is crucial. Among the various types of drill bits available on the market, HSS (high-speed steel) drills are a popular choice for many industrial applications. 

HSS Mechanics Length Drills: HSS mechanics length drills are designed for use in portable power drills or drill presses, and are ideal for general-purpose drilling in materials such as wood, plastic, and soft metals. They are shorter and more rigid than jobber length drills, which makes them less likely to bend or break during use. Mechanics length drills also have a shorter flute length, which reduces chip buildup and enhances chip evacuation, resulting in a cleaner, more accurate hole.

Taper Length Drills: Taper length drills are a longer version of the jobber length drill, with a longer flute length and overall length. They are ideal for drilling deeper holes in materials such as metal and wood, and are often used in applications such as plumbing, electrical work, and construction. The longer length of taper length drills allows for better chip evacuation and reduces the risk of the drill bit overheating, which can lead to dullness and breakage.

Taper Shank Drills: Taper shank drills have a shank that is wider at the base and tapers to a smaller diameter at the tip. They are designed for use in machines with tapered spindles, such as drill presses and milling machines. Taper shank drills are ideal for heavy-duty drilling in materials such as cast iron, steel, and other alloys. They offer superior rigidity and stability during drilling, which helps ensure precision and accuracy.

Jobber Length Drills: Jobber length drills are the most commonly used drill bit for general-purpose drilling in materials such as wood, plastic, and soft metals. They are ideal for use in portable power drills and drill presses, and are available in a wide range of sizes and shapes. Jobber length drills are versatile and affordable, making them a popular choice for DIY projects and light industrial applications.

Extra-Long Aircraft Extension Drills: Extra-long aircraft extension drills are designed for drilling deep holes in difficult-to-reach areas, such as inside pipes or through thick materials. These drills have a long, slender shank that extends beyond the drill chuck, allowing them to reach deep into tight spaces. The extended length also helps to reduce the chance of the drill bit breaking or bending during use. 

Screw Machined Drills: Screw machined drills are specifically designed for use in screw machines, which are used for high-speed, high-volume drilling operations. These drills have a shorter overall length and a shorter flute length, making them more rigid and less likely to flex or break during use. Screw machined drills are commonly made from HSS or cobalt, and are ideal for drilling through materials such as brass, aluminum, and steel.

Choosing the right drill bit depends on the specific application and material being drilled. HSS mechanics length drills are ideal for general-purpose drilling, taper length drills are suitable for deeper holes, taper shank drills are best for heavy-duty drilling, extra-long aircraft extension drills are used for deep hole drilling in tight spaces, while screw machined drills are ideal for high-speed, high-volume drilling in screw machines and jobber length drills are the most versatile and affordable option. Understanding the advantages and applications of each drill bit type can help ensure the best results for your drilling project.
