Drill bit set EINHELL 49205519 — 19-piece HSS drill bits for aluminium, metal, plastic, steel

The EINHELL 49205519 drill bit set contains 19 HSS-G bits in diameters from 1 mm to 10 mm (1 / 1.5 / 2 / 2.5 / 3 / 3.5 / 4 / 4.5 / 5 / 5.5 / 6 / 6.5 / 7 / 7.5 / 8 / 8.5 / 9 / 9.5 / 10 mm). Made from high-performance HSS 4241 steel with a fully ground, highly polished surface, the bits have a 135° split point tip for quick centring and clean, fast drilling. The milled type N helix conforms to DIN 338 for efficient chip removal. The round shanks fit standard drill chucks, and the set is supplied in a practical storage cassette with a transparent lid, auto-lock clip closure, stand-up removal function and a Euro hole hanger for workshop storage.

Advantages

The set covers the most common diameters needed for metalworking and multi-material drilling, offering compatibility with standard cordless screwdrivers and drills via round shanks. HSS 4241 construction and the 135° split point improve centring and drilling speed, while the milled N-helix helps clear chips for precise holes. The storage cassette keeps the bits organised and easy to access, with a transparent lid for quick content checks and a secure auto-lock clip.

Suitable for

• Drilling in iron and general metal profiles
• Working with steel, non‑ferrous metals and aluminium
• Drilling in sheet metal and certain plastics
• DIY, maintenance and workshop tasks using hand drills and cordless screwdrivers

When it may not be suitable

These HSS-G drill bits are not suitable for stainless steel. For hardened or highly abrasive materials, specialist or coated drills may be required to achieve longer tool life and better results.

Key specifications

• Number of pieces: 19
• Diameter range: 1.0–10.0 mm (19 sizes)
• Material: HSS 4241 high-performance steel
• Tip geometry: 135° split point
• Helix type: Milled type N, conforms to DIN 338
• Surface: Fully ground, highly polished (silver finish)
• Shank: Round shank for standard drill chucks
• Suitable materials: Steel, non‑ferrous metals, aluminium, sheet metal, plastic
• Storage: Plastic cassette with transparent lid, auto-lock clip and Euro hole hanger

How to use

Select the drill diameter appropriate for the hole required, clamp the round shank securely in the drill chuck, and set a suitable drilling speed for the material (lower speeds for larger diameters and harder metals). Use steady pressure and allow the bit to cut without forcing; for deeper holes, withdraw periodically to clear chips. When drilling into metal, use cutting oil or lubricant to reduce heat and extend tool life.

What to consider before purchase

• Not suitable for stainless steel—choose coated or specific stainless‑steel drills if needed
• Round shank is compatible with standard chucks but not with quick-change hex systems without an adapter
• Intended for general metalworking and DIY; heavy industrial continuous production may require more wear‑resistant or coated tooling

Usage recommendations

Use cutting fluid for metal drilling, start with a pilot hole for large diameters, and match drill speed to material and diameter to maximise performance and bit life.
