Drill bit for metal GRAPHITE HSS DIN 338 1.5 mm set of 3

GRAPHITE HSS drill bits for metal, conforming to DIN 338, 1.5 mm diameter, set of 3 are straight-fluted solid drills made of high-speed steel for drilling small, precise holes in a wide range of metals and metal alloys. These bits are intended for general-purpose metalworking and maintenance tasks that require a reliable 1.5 mm hole diameter. Their geometry follows the DIN 338 standard, providing consistent performance in manual and machine drilling applications where accuracy and wear resistance are important.

Advantages

The HSS material provides high hardness and heat resistance for drilling into steel, stainless steel, aluminum and other common metal alloys. The straight-fluted design ensures controlled chip evacuation for small-diameter holes, while the solid, single-piece construction reduces chatter and improves concentricity. Supplied as a set of three, the pack supports repeated use and quick replacement when a bit becomes worn or damaged.

Suitable for

• Drilling precise 1.5 mm holes in mild steel and alloy steels
• Working with stainless steel and non-ferrous metals such as aluminum and brass
• Maintenance, repair and general metal fabrication tasks
• Small-diameter pilot holes for fastening and assembly

Key specifications

• Material: high-speed steel (HSS)
• Standard: DIN 338-compliant geometry
• Diameter: 1.5 mm
• Flute type: straight flute
• Quantity: set of 3 identical bits

How to use

Select an appropriate drill chuck or collet that securely holds a 1.5 mm shank. Secure the workpiece and, if possible, clamp it to prevent rotation. Use a drill press or handheld drill at the recommended speeds for the workpiece material; reduce speed for harder metals and increase for softer non-ferrous metals. Apply steady, moderate feed pressure and use cutting lubricant when drilling steel and stainless steel to improve tool life and hole quality. Withdraw the bit periodically to clear chips when drilling deeper holes.

Usage recommendations

For best results, start with a center punch to locate the hole, use appropriate cutting fluid on ferrous materials, and avoid excessive speed or force which can cause premature wear or breakage of small-diameter bits. Replace bits showing significant wear or chipping to maintain hole accuracy.
