Drill Bit AWTools AW42702 — length unspecified, weight 15 g

AWTools AW42702 drill bit is a compact, lightweight accessory engineered for general drilling tasks. Made of high-quality carbon steel with a tungsten carbide cutting blade hardened to 90 HRC and a titanium nitride (TiN) coating, this bit offers enhanced wear resistance and a durable cutting edge. With a total weight of 15 g, it is intended for use in compatible drills where a small, precise bit is required for work in brittle or soft materials.

Advantages

The combination of a carbon steel body and a tungsten carbide blade provides a balance of toughness and cutting performance, while the TiN coating reduces friction and extends tool life. The hardened cutting edge (90 HRC) maintains sharpness during repeated use. Its low weight and compact dimensions make handling easy and reduce operator fatigue during finer drilling operations.

Suitable for

• Drilling in glass and porcelain
• Work on ceramics and stoneware
• Creating holes in brick and masonry
• Drilling in aluminium and other soft metals
• Small repair, workshop and precision applications

Key specifications

• Material: carbon steel body with tungsten carbide cutting blade
• Cutting edge hardness: 90 HRC
• Surface treatment: titanium nitride (TiN) coating
• Weight: 15 g
• Recommended use: low-speed drilling with non-impact mode and suitable coolant

How to use

Install the drill bit securely in a compatible drill chuck, ensuring correct clamping and alignment. Use the drill at slow rotational speed in non-impact mode to avoid chipping in brittle materials. Apply a suitable coolant or lubricant where appropriate to reduce heat and preserve the cutting edge. Start drilling with light pressure, increase gradually as the bit forms a stable cutting path, and avoid sudden lateral forces.

Usage recommendations

For best results when drilling glass, ceramics, porcelain or stoneware, use low speed, non-impact drilling and a steady stream of coolant. When working with metals such as aluminium, maintain moderate feed pressure and ensure proper chip evacuation. Inspect the bit periodically for wear and replace if cutting performance decreases.
