Mte HSS-E DIN 338 Drill Bit Cylindrical Shank Short Gold Series 5 mm

Gold Series, High Durability for M6 and Special Fastenings in Challenging Materials

The Mte HSS-E DIN 338 Drill Bit (5.0 mm) Gold Series is a high-performance cutting tool designed for professional and industrial drilling operations. This drill bit is optimized to deliver superior performance and extended life, especially in difficult-to-machine materials such as stainless steels (INOX), hardened steels, and high-alloy cast materials. Its 5.0 mm diameter is a critical size for operations like pre-drilling for M6 metric standard threads with approximately 75% thread engagement or creating pilot holes.

The product's strength comes from its HSS-E (Cobalt Alloy High-Speed Steel) material, which offers high-temperature resistance, and its Gold Series (TiN or similar) coating, which reduces friction and extends tool life.

Technical Specifications and Material Details

The Mte Drill Bit is manufactured for high standards and demanding working conditions.

Feature Name

Detailed Description

Diameter (Nominal)

5.0 mm

Standard

DIN 338: International German standard for twist drill bits with cylindrical shanks and standard short length.

Material Type

HSS-E (Cobalt Alloy 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 (Approx.)

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

Cutting Direction

Right-hand cut

Application Areas and Industries Used

This drill bit is used in critical applications, especially for precise tapping operations (especially in difficult-to-machine materials) and drilling hard-to-process materials:

Machine Manufacturing and Tool & Die Making: Pre-drilling for M6 metric threads (especially in hard or flat materials like stainless steel to reduce load on the tap) and machining hardened tool steels.

Automotive and Ancillary Industries: Drilling holes for M6 connection points in engine, chassis, and critical components.

Electronics and Precision Engineering: Drilling small assembly holes requiring high strength and precision.

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

General Metal Fabrication: All drilling operations requiring special tolerances or metric thread standards.

User Information and Benefits

This product caters to professional users seeking consistent high performance, long life, and precise tolerances in challenging materials:

Tap Protection in M6 Tapping: The 5.0 mm diameter reduces thread engagement to approximately 75% for M6 (1.0 mm pitch) threads. This significantly reduces the risk of tap breakage, especially in stainless steel or thick-walled parts, while ensuring acceptable joint strength.

Stainless Steel and Hard Material Capability: Thanks to its HSS-E (Cobalt) content, it exhibits high heat resistance even in difficult-to-machine materials, extending tool life.

Cost/Efficiency Optimization: TiN coating reduces friction and heat, extending tool life. This reduces production downtime and operating costs.

Precise Starting: The 135° split point geometry prevents the drill from walking (skating) on the material and reduces the need for a pilot drill, ensuring high-precision hole starts.
