Gold Series, for M2.5 Pre-Tapping and Precise Micro Drilling in Challenging Materials
The Mte HSS-E DIN 338 Drill Bit (2.0 mm) Gold Series is a high-performance cutting tool with a very small diameter, designed for professional and industrial drilling operations. This drill bit is optimized to deliver superior performance, precision, and longevity, especially in materials where standard HSS bits struggle, such as stainless steels (INOX), hardened steels, and high-alloy materials. Its 2.0 mm diameter is critically important in micro and precision applications, as it is the ideal pilot hole diameter for M2.5 metric standard threads.
The product's strength comes from its HSS-E (Cobalt Alloyed High-Speed Steel) material, which offers high-temperature resistance, and its Gold Series (TiN or similar) coating, which extends tool life and reduces friction.
Technical Specifications and Material Details
The Mte Drill Bit is manufactured to high standards for use in demanding working conditions.
| Feature Name | Detailed Description |
| Diameter (Nominal) | 2.0 mm |
| Standard | DIN 338: International German standard for spiral drill bits with cylindrical shanks and standard short length. |
| Material Type | HSS-E (Cobalt Alloyed High-Speed Steel): Contains 5% Cobalt alloy (mostly M35 steel), providing exceptional resistance to high temperatures (Red Hardness). This maintains sharpness and durability even at high cutting speeds. |
| Surface Treatment | Gold Series (Typically Titanium Nitride - TiN Coating): A hard, thin, gold-colored coating. Increases wear resistance, reduces the coefficient of friction, and decreases heat buildup, thereby extending tool life. |
| Shank Type | Cylindrical Shank: Compatible with standard drill chucks. |
| Point Angle (Approximate) | Generally 135° point angle and split point geometry. This aids in excellent centering by reducing the need for a pilot hole. |
| Cutting Direction | Right Hand Cutting |
Applications and Industries Used
This drill bit is particularly used in critical applications requiring precise tapping operations of very small diameters and drilling difficult-to-machine materials:
Machinery Manufacturing and Toolmaking: Ideal for drilling pilot holes for M2.5 metric threads (for standard 0.45 mm thread pitch).
Electronics and Micro Mechanics: Drilling mounting holes requiring high strength and precision at micro dimensions (Sensor, miniature motor, and optical device assemblies).
Medical Device Manufacturing: Drilling small stainless and biocompatible parts.
Hobby and Model Making: Fine work requiring holes in metal, resin, and other hard materials.
General Metal Fabrication: All drilling operations requiring critical strength and precision.
User Information and Benefits
This product caters to professional users seeking consistent high performance, long life, and precise tolerances in challenging materials:
Ideal Diameter for M2.5 Thread: The 2.0 mm diameter is the ideal pilot hole diameter for M2.5 (0.45 mm pitch) threads, ensuring that more than approximately 80% of the thread profile is formed. This guarantees maximum thread strength.
Stainless Steel and Hard Material Capability: Thanks to its HSS-E (Cobalt) content, it exhibits high heat resistance even in hard-to-machine materials like stainless steels, extending tool life.
Cost/Efficiency Optimization: TiN coating reduces friction and heat, extending tool life. This reduces production downtime and operating costs.
Excellent Centering: The 135° split point geometry prevents the drill from walking (skating) on the material and reduces the necessity of using a pilot drill, providing highly accurate hole starting even at small diameters.
Resistance to Breakage in Small Diameters: The cobalt alloy offers additional toughness and temperature resistance, which helps reduce the risk of breakage in small-diameter HSS bits.
