Drill bit pack AWTools AW42020 — 10 pieces

AWTools AW42020 — 10 pieces drill bit pack contains ten identical HSS-Co high-speed steel bits with 5% cobalt, precision ground and featuring two cutting edges and a centering point with a 135° angle. Packaged in a compact case, the set is intended for use with handheld and stationary drills and provides ready replacements for repetitive drilling tasks in compatible materials.

Advantages

The drill bits are made of HSS-Co high-speed steel with 5% cobalt for improved hot hardness and wear resistance during prolonged drilling. Precision ground cutting edges and a two-flute geometry ensure accurate hole entry and stable chip evacuation. The 135° centering point reduces walking on the workpiece and facilitates accurate positioning without the need for a pilot hole.

Suitable for

• Drilling alloyed and unalloyed steel
• Working with grey cast iron
• Drilling non-ferrous metals such as aluminum and brass
• Drilling plastic components
• Use in construction, repair and maintenance tasks requiring multiple spare bits

Key specifications

• Material: HSS-Co high-speed steel with 5% cobalt
• Geometry: precision ground with two cutting edges
• Point angle: 135° centering point
• Compatibility: designed for use with handheld and stationary drills
• Quantity: 10 identical drill bits in a storage case

How to use

Select the appropriate drill bit size for the required hole and secure it in the drill chuck. Clamp the workpiece or secure it in a vice to prevent movement. Start drilling at low speed to establish the hole center, then increase speed within the recommended range for the material. Use cutting fluid or lubricant when drilling steels and cast iron to reduce heat and prolong bit life. Withdraw the bit periodically to clear chips when drilling deep holes.

Usage recommendations

For best performance, match drill speed and feed to the material being machined and maintain proper cutting fluid application when working with steel or cast iron. Inspect bits periodically and replace when the cutting edges show signs of wear or chipping.
