HSS drill bit set Metabo 627153000 — 19 pieces, DIN 338, cylindrical shank

The HSS drill bit set Metabo 627153000 contains 19 high-speed steel twist drills produced to DIN 338 standards with cylindrical shanks. The set covers a practical range of metric sizes for general workshop and metalworking tasks. Hardened and ground flutes provide consistent cutting geometry, while the HSS material offers improved wear resistance and heat tolerance compared with carbon steel bits. The cylindrical shank allows reliable clamping in standard chucks and drill presses.

Advantages

The HSS construction ensures durability and stable cutting performance during repeated drilling of steel, non-alloyed metals and similar materials. Manufacturing to DIN 338 guarantees uniform geometry and tip angle for predictable chip removal and reduced walking when starting a hole. The set format keeps a range of commonly used sizes together for quick selection, while cylindrical shanks provide compatibility with a wide variety of hand and machine chucks.

Suitable for

• Drilling mild steel, cast iron and non-ferrous metals
• General workshop and maintenance tasks
• Use with hand drills and drill presses
• Hobby and professional metalworking projects

Key specifications

• Number of pieces: 19
• Material: high-speed steel (HSS)
• Standard: DIN 338 (twist drill geometry)
• Shank type: cylindrical (straight) shank
• Intended materials: steel, cast iron, non-ferrous metals
• Finish: ground flutes and sharpened tips

How to use

Select the appropriate drill diameter for the hole required, secure the workpiece using clamps or a vise, and ensure the drill is mounted firmly in the chuck. Use an appropriate spindle speed and feed rate for the material being drilled; lower speeds for harder metals and higher speeds for softer materials. Apply cutting fluid or lubricant when drilling steel to reduce heat and improve tool life. Withdraw the drill periodically to clear chips and prevent clogging.

Usage recommendations

Store the drill bits in their case or a dedicated holder to protect the cutting edges. Regularly inspect for wear or damage and re-sharpen or replace bits as needed. For improved performance on hardened or abrasive alloys, consider using coated or carbide-tipped drills designed for those materials.
