Identifying Metal Drills: How to Recognize a Metal Drill?

Steel drills, often called spiral flute drills, feature a tapered front with two sharp cutting edges. Their defining characteristic is a sharp tip, perfect for penetrating metal. The spiral flutes extend up to the shank, ensuring efficient chip removal.

Which drills are best for stainless steel?

For machining tough materials like stainless steel, VA solid carbide or HSS drills are ideal. BSG's RT 100 VA solid carbide drill, with a 140° point angle and 30° helix angle, is a specialist tool. Tools with adapted geometry help reduce heat and generate short chips in long-chipping materials. A solid carbide drill with a hard material coating will yield optimal results.

Which drill is suitable for hardened steel?

Hardened steel, heated between 750 to 1050 °C to enhance mechanical resistance, requires a solid carbide drill with a TiAIN coating, such as BSG's RT 100 HF Ratio drill.

The coating's microstructure features fine TiAlN nanocrystals in a high-temperature-resistant silicon nitride matrix, ensuring high hardness.

BSG Drill Manufacturing Excellence

The drill manufacturing process includes grinding the cutting edges, where the microdesign determines if the edge is sharp or rounded under a microscope. High-quality drills avoid cutting edge roughness, increasing stability and surface finish quality. Cutting edge preparation techniques include wet blasting, micro blasting, drag finishing, and robotic brushing.

Twist Drill

What are twist drills?

Twist drills encompass various types such as:metal drills, plastic drills, wood drills, universal drills, masonry and concrete drills All twist drills share a distinctive helical flute design. The choice of twist drill depends on the material's hardness, categorized into three main types.

Solid Carbide Drill: What is Carbide?

Carbide is a sintered material, created by heating under pressure, comprising a blend of various carbides and cobalt, hence the term sintered carbide metals.

Applications of Carbide Drills: Where is Carbide Used?

Carbide is acclaimed as a premium cutting material for tools such as drills, lathe tools, and milling tools. Renowned for its elevated cutting values, extended tool life, and superior drilling quality, carbide tools are indispensable for series and large-scale production on CNC machines with stable clamping systems. Despite their higher purchase price compared to HSS tools, carbide tools offer unmatched performance. However, in scenarios where machining conditions are unstable or batch sizes are small, high-speed steel (HSS) tools emerge as the more economical and practical choice.

What is a solid carbide drill?

With solid carbide drills, the tool body and cutting edges comprise different cutting materials. Contrarily, a purely solid carbide drill is entirely crafted from carbide, making it ideal for rigorous machining tasks that demand high wear resistance and unparalleled efficiency. At Shanghai BSG Industrial Co., Ltd., the journey to creating a flawless solid carbide drill begins with the meticulous composition of the cutting material, reflecting BSG's dedication to excellence by manufacturing its own carbide.
