Drill bit set AWTools AW41155, 5 pieces, pack weight 760 g

AWTools AW41155 drill bit set contains five precision ground HSS-G bits supplied in a compact case with a total pack weight of 760 g. The bits are double-sided and feature a 118° point angle for improved centering and consistent chip formation. The set is designed for general drilling tasks in a range of materials and provides spare bits for workshop, construction and home repair use.

Advantages

The AWTools AW41155 set is made from HSS-G high-speed steel, offering wear resistance and heat tolerance for repeated drilling operations. Precision grinding ensures accurate diameter and concentricity, while the double-sided design allows the bits to be re-sharpened or turned for extended service life. A 118° point angle improves starting accuracy on flat surfaces and reduces walking, resulting in cleaner holes and easier pilot drilling.

Suitable for

• Drilling alloyed and unalloyed steels
• Working with grey cast iron and non-ferrous metals
• Drilling plastics and similar synthetic materials
• Routine workshop maintenance and production tasks
• Home repair and construction site jobs requiring multiple spare bits

• Pack weight: approximately 760 g

How to use

Select a drill bit of the required diameter from the case and secure it in a compatible drill chuck. Use appropriate cutting speed and feed for the workpiece material; reduce speed for harder steels and increase for softer non-ferrous metals and plastics. Apply cutting fluid or coolant when drilling steels to reduce heat and extend bit life. Ensure the workpiece is clamped securely and start drilling with steady pressure, allowing the bit to do the cutting without excessive force. Reverse or resharpen the bit when wear is detected, and replace with a spare if damage occurs.

Usage recommendations

For best results, use the AWTools AW41155 bits with a properly aligned drill and suitable coolant when working with alloyed steels. Store bits in the provided case to protect cutting edges and keep sizes organized; inspect bits periodically and re-grind or replace when signs of rounding or chipping appear.
