Drill bit set AWTools AW41925 — pack of 5

AWTools AW41925 — pack of 5 is a set of five precision ground drill bits made of HSS‑G M2 high‑speed steel with black oxide finish. Each bit features two cutting edges and a centering point with a 135° point angle, providing consistent start and reduced walking when drilling. The set is supplied in a compact case and is intended for general drilling tasks on alloyed and unalloyed steel, grey cast iron, non‑ferrous metals and plastic, suitable for use with compatible hand and machine drills.

Advantages

The HSS‑G M2 material offers high wear resistance and good toughness, reducing the risk of breakage during routine workshop and construction use. Precision grinding and two cutting edges ensure accurate hole geometry and efficient chip removal, while the black oxide surface improves corrosion resistance and extends service life. The 135° centering point helps achieve precise starts and lowers the need for pre‑centering on many materials. Supplied in a case for organized storage and easy transport.

Suitable for

• Drilling holes in alloyed and unalloyed steel
• Working with grey cast iron
• Drilling non‑ferrous metals such as aluminium and brass
• Creating holes in various plastics
• Replacement bits for continuous production or field repairs

Key specifications

• Material: HSS‑G M2 high‑speed steel
• Finish: black oxide
• Cutting geometry: precision ground, two cutting edges
• Point angle: 135° centering point
• Pack quantity: 5 drill bits in a storage case
• Typical use: suitable for metal and plastic drilling

How to use

Select a drill bit size that matches the required hole diameter and secure it in the chuck of a compatible hand drill or drill press. Use an appropriate spindle speed and feed for the material being drilled — lower speeds for harder metals and higher speeds for non‑ferrous metals and plastics. Apply steady, even pressure and allow the bit to cut without excessive force; withdraw occasionally to clear chips when drilling deeper holes. For improved accuracy on hard materials, consider using a center punch or pilot hole before final drilling.

Usage recommendations

To maximize tool life and hole quality, use cutting fluid or lubricant when drilling steel and cast iron, and reduce speed when working with plastics to avoid melting. Store the bits in their case to protect cutting edges and keep sizes organized for quick replacement during continuous tasks.
