Einhell set di punte per metallo HSS-Co 19 pz. con gambo triangolare, Ø 1–10 mm (49249019)

For metalworkers and DIY enthusiasts tackling steel, cast iron, non-ferrous metals, or plastics, this 8-piece drill bit set covers the most common small diameters from 1 mm to 4.5 mm. The cobalt-alloyed HSS-Co steel withstands high drilling temperatures, keeping the cutting edges sharp longer than standard HSS bits.

Key specifications

• Drill bit type: twist drill bit
• Material: HSS-Co (high-speed steel with cobalt)
• Number of pieces: 8
• Diameters included: 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm
• Shank type: cylindrical
• Suitable materials: steel, cast iron, non-ferrous metals, plastics

Why choose it

Cobalt alloying increases hardness and heat resistance, making these bits a reliable choice for repetitive drilling in tough metals. The set's graduated sizes let you pre-drill pilot holes and finish to exact dimensions without switching brands.

Ideal use cases

• Drilling precise holes in sheet metal, profiles, and machine parts
• Creating pilot holes for screws or rivets in metal assemblies
• Working on automotive, HVAC, or metal fabrication projects
• Drilling plastics and non-ferrous metals without bit changes

Good to know

Store the bits in the original packaging or a drill bit index to protect the cutting edges. Use cutting fluid when drilling steel to extend bit life.
