Drill bit AWTools AW42703 — model AW42703, weight 20 g

The AWTools AW42703 drill bit is a single, lightweight replacement bit manufactured from high-quality carbon steel with a tungsten carbide cutting tip and a titanium nitride (TiN) coating. Weighing approximately 20 g, this bit is intended for general drilling tasks and is compatible with standard drill chucks. Its construction and cutting geometry are optimized for controlled drilling in brittle and soft materials when used at low speeds and with appropriate cooling.

Advantages

The tungsten carbide blade with a hardness of 90 HRC provides wear resistance and prolonged cutting edge life, while the TiN coating reduces friction and improves surface durability. The carbon steel body gives sufficient toughness for handling light workshop and household tasks. The compact, single-bit format makes it convenient as a spare part or as an individual tool in a drill bit assortment.

Suitable for

• Drilling in glass and ceramics
• Working with porcelain and stoneware
• Drilling brick and masonry for light duties
• Drilling aluminium and other soft metals
• Use as a replacement bit in household and workshop drills

Key specifications

How to use

Secure the AWTools AW42703 drill bit in the drill chuck ensuring proper alignment and firm clamping. When drilling brittle or hard-coated materials such as glass, ceramics or porcelain, operate the drill at low speed, apply steady, moderate pressure, and use a non-impact drilling mode. Apply suitable coolant or water to reduce heat build-up and prolong the life of the tungsten carbide tip. For metal work, select a low to moderate speed appropriate for the material and maintain a steady feed to prevent chipping of the cutting edge.

Usage recommendations

Use non-impact drilling mode, low speeds and continuous cooling for best results. Inspect the cutting tip before use and replace the bit when signs of wear, chipping, or significant loss of cutting performance appear.
