Mte HSS-E DIN 338 Drill Bit Cylindrical Shank Short Gold Series 3 mm

Gold Series, High Durability in Challenging Materials and Use Before M3.5 Threading

Mte HSS-E DIN 338 Drill Bit (3.0 mm) Gold Series is a high-performance small-diameter cutting tool designed for professional and industrial drilling operations. This drill bit is optimized to deliver superior performance and long life, especially in materials that challenge standard HSS bits, such as stainless steels (INOX), hardened steels, and high-alloy materials. The 3.0 mm diameter is a critical measurement, ideal for use as a pre-drilling hole for M3.5 metric standard threads or for special precision applications.

The product's strength comes from its high-temperature resistant HSS-E (Cobalt Alloyed High-Speed Steel) material and the Gold Series (TiN or similar) coating, which increases tool life by reducing 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)

3.0 mm

Standard

DIN 338: International German standard for cylindrical shank (stem) and standard short-length twist drill bits.

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): 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)

Typically 135° point angle and split point geometry. This helps with excellent centering by reducing the need for a pilot hole.

Direction of Cut

Right Hand Cut

Areas of Use and Industries Served

This drill bit is particularly used in critical applications requiring small-diameter precision threading and drilling of difficult-to-machine materials:

Machine Manufacturing and Mold Making: Pre-drilling for M3.5 metric threads (for standard 0.6 mm pitch).

Electronics and Precision Engineering: Drilling small-sized assembly holes requiring high strength and precision (M3.5 or M3 bolt clearance holes).

Automotive and Ancillary Industry: Drilling connection points in small control parts and precision components.

Marine and Chemical Industry: Drilling in stainless steel (INOX) materials, which is essential due to high corrosion resistance.

General Metal Fabrication: Especially for preparing M3 bolt clearance holes or opening small pin recesses.

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 M3.5 Thread: The 3.0 mm diameter is the ideal pre-drilling diameter for M3.5 (0.6 mm pitch) threads, providing maximum thread engagement (theoretically the highest 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 need for a pilot drill, providing highly accurate hole starting.

Resistance to Breakage in Small Diameters: The cobalt alloy offers additional toughness and temperature resistance that helps reduce the risk of breakage in small-diameter HSS bits.
