Drill bit set AWTools AW42710 — 5 pieces, pack weight 125 g

AWTools AW42710 drill bit set includes five bits in a compact plastic case, total pack weight 125 g. The bits are made of high-quality carbon steel with tungsten carbide cutting edges hardened to approximately 90 HRC and a titanium nitride (TiN) coating. The set is intended for use with standard power drills at low speed and non-impact mode, and it is supplied as a small consumer pack for workshop, construction or DIY tasks where multiple spare bits are required.

Advantages

The tungsten carbide cutting edges provide high wear resistance and maintain sharpness when working with abrasive materials. The TiN coating reduces friction and improves heat resistance, extending service life during low-speed drilling. Hardened cutting tips at about 90 HRC increase durability, while the carbon steel body offers structural strength and easy handling. The included plastic case keeps the five bits organized and protected for transport and storage.

Suitable for

• Drilling glass and ceramics
• Working with porcelain and stoneware
• Drilling brick and masonry surfaces
• Creating or enlarging holes in aluminium and other soft metals
• General workshop and DIY drilling tasks requiring spare bits

Key specifications

How to use

Install the appropriate bit into the drill chuck and tighten securely. Operate the drill at low speed and disable hammer or impact functions. For materials such as glass, ceramics or porcelain, apply steady, light pressure; use a suitable coolant or water to reduce heat and remove debris. For masonry and aluminium, select the correct feed pressure and maintain hole alignment. Replace bits when cutting performance decreases or when wear is observed on the tungsten carbide edge.

Usage recommendations

Use with non-impact drilling mode and appropriate coolant; avoid high rotational speeds to prevent overheating and premature wear. Store bits in the provided plastic case to protect cutting edges and prevent damage.
