Drill bits GRAPHITE HSS DIN 338 for metal, 1 mm, set of 3

Set of three GRAPHITE HSS DIN 338 drill bits with 1 mm diameter, designed for drilling small, precise holes in steel and other metals. Made from high-speed steel (HSS) and produced to DIN 338 geometric and tolerance standards, the set is intended for workshop and DIY use with hand drills or drill presses. The compact set provides consistent cutting geometry for fine metalworking tasks where accuracy and heat resistance are important.

Advantages

High-speed steel construction provides good wear resistance and thermal stability under typical metal drilling conditions. The DIN 338 geometry ensures precise centering, consistent chip evacuation, and predictable cutting performance. A 1 mm diameter is suited for fine, detailed holes and pilot drilling; the three-piece set offers spare bits for repetitive tasks or backup during projects. Suitable flute design reduces clogging and helps maintain drilling accuracy in thin and medium-thickness metal sheets.

Suitable for

• Drilling small-diameter holes (1 mm) in mild steel, stainless steel, aluminum and non-ferrous metals
• Pilot holes for taps or larger drill operations
• Model making, electronics chassis work and precision metal fabrication
• Use with hand drills and drill presses in home workshop and professional settings

Key specifications

• Material: high-speed steel (HSS)
• Standard geometry: DIN 338-compliant
• Diameter: 1 mm
• Quantity: set of 3 drill bits
• Tip type: ground point for accurate centering
• Flute design: two-flute spiral for chip evacuation

How to use

Secure the workpiece and mark the drilling position precisely. Use an appropriate center punch if needed to prevent walking. Fit the 1 mm drill bit into the chuck and tighten firmly. Use a suitable cutting speed and moderate feed for the material being drilled; apply cutting fluid when working with steel or harder alloys to reduce heat and wear. Start drilling at low speed to establish the hole, then increase speed as stability allows. Withdraw periodically to clear chips and maintain cutting effectiveness.

Usage recommendations

For longest life, use light cutting pressure and adequate lubrication when drilling steel; avoid excessive lateral forces that can break small-diameter bits. Store the set in a protective holder and replace worn or chipped bits to maintain hole quality and operator safety.
