Sada vrtákov Metabo HSS kov 19-dielna DIN 338, valcová stopka (627151000)

The Metabo HSS Metal 19-piece twist drill bit set (DIN 338) is designed for reliable drilling in steel and other ferrous materials. The set contains a selection of high-speed steel (HSS) bits with cylindrical shanks manufactured to DIN 338 specifications, offering consistent geometry and concentricity for straight, accurate holes. Bits are arranged for general metalworking tasks in workshops and professional environments and come in a compact storage case for organized transport and access.

Advantages

The HSS material delivers good hardness and heat resistance for standard drilling in mild and alloy steels. DIN 338 geometry ensures stable centering, reduced walking on the workpiece and uniform cutting performance across sizes. Cylindrical shanks fit common drill chucks without adapters, enabling fast tool changes and secure clamping. The 19-piece range covers common diameters so you can select the right size for routine metalworking jobs and repairs.

Suitable for

• Drilling holes in mild and alloy steels
• Workshop maintenance and toolroom tasks
• General metal fabrication and repair work
• Use with bench drills and hand-held corded or cordless drills equipped with standard chucks

Key specifications

• Material: High-speed steel (HSS)
• Standard: DIN 338 (twist drill geometry)
• Shank type: Cylindrical shank for standard chucks
• Number of pieces: 19
• Intended use: Drilling in ferrous metals
• Storage: Compact case for organized storage and transport

How to use

Select the appropriate drill diameter for the required hole, secure the workpiece in a vice or with clamps, and mark the drilling center. Fit the cylindrical shank into the drill chuck and tighten securely. Use moderate feed pressure and appropriate spindle speed for the material and diameter: lower speeds for larger diameters and harder steels, higher speeds for smaller diameters and softer steels. Apply cutting lubricant when drilling steel to reduce heat and extend tool life. After drilling, remove burrs with a deburring tool or file if required.

Recommendations

For best performance, use cutting fluid when drilling steel and adjust speed according to diameter: reduce RPM for larger bits and increase RPM for smaller bits. Inspect bits for wear and replace any with pronounced wear, chipping or blunt cutting edges to maintain hole quality and operator safety.
