Drill Bit A Forged Tool 09084058 81700568100 Alpen-Maykestag

Alpen-Maykestag A Forged Tool 09084058 drill bit set, model 81700568100, contains three SDS-plus hammer drill bits with diameters 5 mm, 6 mm and 8 mm and a length of 160 mm each. These bits are designed for hammer drilling in concrete, reinforced concrete, natural stone, masonry and cement. The bits feature quadruple stepped profiles, a patented hardened metal tip and two cutting edges to ensure accurate centring and sustained performance under heavy use.

Advantages

The Alpen SDS-plus drill bits offer precise drilling thanks to excellent centring properties and two cutting edges. Their hardened metal tips and vacuum hardening process increase robustness and wear resistance, while the quadruple stepped profile boosts drilling efficiency in hard materials. The set provides a range of common diameters for typical masonry and concrete tasks.

Suitable for

• Hammer drilling in concrete and reinforced concrete
• Drilling in natural stone and masonry walls
• Installing anchors, dowels and fasteners in cement-based substrates

How to use

Insert the SDS-plus shank securely into the compatible hammer drill. Select the correct drill diameter for the anchor or fixture, mark the drilling point, and start drilling using the hammer function for concrete and masonry. Apply steady pressure and allow the bit to remove debris; withdraw occasionally to clear the hole and avoid overheating. For through-holes or deep holes, clear dust frequently to maintain drilling speed and accuracy.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection, dust mask) when hammer drilling. Match the SDS-plus bits with a drill rated for hammer or rotary‑hammer operation. Replace bits when wear or tip damage reduces centring accuracy or drilling performance.
