Mte HSS-E DIN 338 Drill Bit Cylindrical Shank Short Gold Series 10 mm

Gold Series, High Durability and Versatile Use in Challenging Materials

The Mte HSS-E DIN 338 Drill Bit (10.0 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 long life, especially in materials where standard HSS bits struggle, such as stainless steels (INOX), hardened steels, and high-alloy cast materials. Its 10.0 mm diameter is a critical and widely used size in general mechanical engineering applications, such as pilot drilling for metric threads like M10 and M12 (with slightly reduced thread engagement) or for clearance holes for bolts.

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 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)

10.0 mm

Standard

DIN 338: International German standard for twist 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): Hard, thin, and gold-colored coating. Increases wear resistance, reduces the coefficient of friction, and minimizes heat buildup, thereby significantly extending tool life.

Shank Type

Cylindrical Shank: Compatible with standard drill chucks.

Point Angle (Approximate)

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

Cutting Direction

Right Hand Cut

Areas of Use and Industries Served

This drill bit is used for general-purpose drilling as well as for materials that are difficult to machine:

Machine Manufacturing and Toolmaking: Clearance holes for M12 bolts or pilot holes for M10 standard threads with reduced thread engagement.

Heavy Industry and Construction: Drilling thick steel plates, profiles, and high-strength fasteners.

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

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

General Metal Fabrication: A commonly used diameter in industrial assembly and manufacturing projects.

User Information and Benefits

This product appeals to professional users seeking consistent high performance, long life, and cost-effectiveness in demanding materials:

Superiority in Challenging Materials: Thanks to its HSS-E (Cobalt) content, it exhibits high heat resistance even in hard-to-machine materials like stainless steel, extending tool life.

Versatile Use: The 10 mm diameter is an ideal intermediate size for professionals who want to drill slightly larger holes to reduce the risk of tap breakage when preparing for common metric threads like M10 (8.5 mm pilot hole) and M12 (10.2 mm pilot hole). It also serves as a comfortable clearance hole for M10 bolts.

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 on the material and reduces the need for a center drill, ensuring highly accurate hole starting.
