Identifying Metal Drills: How to Recognize a Metal Drill?

Steel drills, often referred to as twist drills or spiral flute drills, feature a tapered front with two sharp cutting edges and a characteristic sharp tip ideal for metal penetration. The spiral flutes extend to the shank for efficient chip removal.

Which Drills Are Suitable for Stainless Steel?

For machining tough materials like stainless steel, Type VA solid carbide or HSS drills are recommended. BSG's RT 100 VA solid carbide drill, with a 140° point angle and 30° helix angle, is specially designed to reduce temperature and generate short chips in long-chipping materials. For optimal results, use solid carbide drills with appropriate coatings.

Which Drill is Suitable for Hardened Steel?

Hardened steel, treated at 750 to 1050 °C to enhance mechanical resistance, requires solid carbide drills with TiAIN coating. The RT 100 HF Ratio drill from BSG is highly recommended.

The TiAlN coating features a microstructure with ultra-fine TiAlN nanocrystals in a glass-like, high-temperature-resistant silicon nitride matrix, ensuring exceptional hardness and durability.

BSG Drills: Excellence in Precision and Performance

Our drill manufacturing includes meticulous grinding of cutting edges. The microdesign of the cutting edge, whether sharp (jagged) or rounded, significantly impacts stability and surface finish quality. Cutting edge preparation techniques include wet blasting, micro blasting, drag finishing, and robotic brushing.

Twist Drill: Versatile and Reliable

What are Twist Drills?

Twist drills encompass various types such asmetal drills, plastic drills, wood drills, universal drills, masonry, and concrete drills . They all share the common feature of helical flutes, which define their name. The choice of twist drill depends on the material's hardness, divided into three primary types.

Solid Carbide Drill: The Pinnacle of Durability. What is Carbide?

Carbide is a sintered mixture of various carbides and cobalt, created under high pressure and temperature, earning the term sintered carbide metals.

Applications of the Carbide Drill: Where is Carbide Used?

Carbide, revered for its exceptional cutting capabilities, is predominantly employed in crafting precision tools such as drills, lathe tools, and milling devices. The remarkable cutting values, extended tool longevity, and superior drilling quality make carbide tools indispensable for series and large-scale CNC productions where stable clamping is guaranteed. Despite the higher initial cost compared to HSS tools, the investment in carbide often pays off in the long run. However, in scenarios where economic efficiency is paramount, high-speed steel (HSS) tools shine, particularly under unstable conditions and in small batch operations.

What defines a solid carbide drill?

Solid carbide drills are the epitome of cutting excellence, crafted entirely from carbide, unlike other tools that only feature carbide edges. Each solid carbide drill is tailored for demanding machining tasks, offering unparalleled wear resistance and operational efficiency. The journey to creating a flawless solid carbide drill begins with the meticulous formulation of the cutting material. At Shanghai BSG Industrial Co., Ltd., we pride ourselves on producing our own superior-grade carbide, ensuring every drill meets the highest standards of precision and durability.
