Drill Bit A Forged Tool 09084072 100606100 Alpen-Maykestag

Alpen Cobalt Drill Bits Case — 6 pieces. These cobalt twist drills are designed with a specially sharpened, self-centering tip and forged construction for high durability and precision. Made from cobalt alloy to withstand higher temperatures and increased wear, the set covers common diameters for metal and plastic work and is intended for professional and DIY use.

Advantages

The cobalt material provides improved resistance to breakage and thermal stress up to 600° C. A special tip geometry allows more accurate self-centering and requires up to 50% lower feed pressure compared with standard drills. The set includes a range of diameters for flexibility on construction steel, alloy steels, stainless steel, copper, brass, aluminum and plastic.

Suitable for

• Drilling holes in construction steel and alloy steels
• Drilling stainless steel and other hard metals
• Working with copper, brass and aluminum

How to use

Secure the selected drill bit in a suitable chuck and ensure the workpiece is clamped. Use cutting fluid when drilling metals to reduce heat and prolong bit life. Start at low speed to allow the self-centering tip to locate the hole, then increase speed and apply steady, moderate feed; the special sharpening permits lower feed pressure but maintain stable contact to avoid wandering. Clear chips frequently and avoid excessive overheating.

Usage recommendations

For best results on hard steels and stainless steel, use a drill press when possible, maintain cutting fluid application, and replace bits once wear affects centring or cutting performance.
