# HSS-Co Twist Drill Bit Set | 19 Pieces<\/p>\n
**Part Number:** 637004<\/p>\n
This high-quality, 19-piece HSS-Co (High-Speed Steel alloyed with Cobalt) screw tap drill bit set has been developed for precise drilling tasks, especially for automotive body repair work and general metalworking applications. The drill bits comply with the strict DIN 338 standard, ensuring consistent quality and performance.<\/p>\n
## Product Description and Key Features<\/p>\n
The screw tap drill bits included in the set feature a cylindrical shank, which is ideal for machine chucking, ensuring stable and vibration-free operation. The material of the drill bits is HSS (High-Speed Steel), enhanced with cobalt, which significantly increases the tools' wear resistance and service life, especially when machining harder materials.<\/p>\n
In terms of surface treatment, the drill bits are available in a bright or steam-tempered finish, which further enhances durability and reduces friction during drilling.<\/p>\n
**Design and Geometry:**<\/p>\n
* **Type:** Type N design, suitable for universal application.
\n* **Cutting Direction:** Right-hand cutting design.
\n* **Point Angle:** 118\u00b0 point angle, allowing for optimal centering and precise drilling.
\n* **Edges:** Every drill bit is equipped with two cutting edges, resulting in efficient material removal and a clean hole surface.<\/p>\n
The set is the ideal choice for anyone looking for reliable, long-lasting tools capable of handling various metal materials.<\/p>\n
## Technical Data and Contents<\/p>\n
The 19-piece set covers a comprehensive range of sizes that satisfy most common drilling requirements. The sizes follow each other in increments of 0.5 mm, guaranteeing precise size selection.<\/p>\n

## Advantages and Application Areas<\/p>\n
The HSS-Co drill bits are highly resistant to high temperatures due to their cobalt content, which is essential for high-speed drilling or when machining difficult materials.<\/p>\n
**Key Advantages:**<\/p>\n
1. **Increased Lifespan:** The cobalt alloy ensures a longer lifespan for the tools compared to conventional HSS drills.
\n2. **Precise Holes:** The 118\u00b0 point angle and manufacturing according to DIN 338 standard guarantee precise dimensional accuracy.
\n3. **Versatility:** Suitable for general-purpose metals, including alloys and tool steels, as well as certain stainless steels (due to cobalt content).
\n4. **Easy Machine Handling:** The cylindrical shank provides excellent gripping stability in drilling machines.<\/p>\n
This set is an indispensable tool in professional workshops where reliability and durability are key.<\/p>\n
