Drill bit AWTools AW42708, weight 35 g, straight shank

The AWTools AW42708 drill bit is a compact, lightweight drilling accessory designed for use with hand drills and drill drivers. It features a straight (cylindrical) shank for compatibility with chucks that accept non-tapered bits. Made of high-quality carbon steel with a tungsten carbide cutting tip and a titanium nitride (TiN) coating, this 35 g bit is intended for precise, controlled drilling in brittle and soft materials.

Advantages

The combination of a tungsten carbide blade rated at 90 HRC and a TiN coating extends cutting life and improves heat resistance during slow-speed operations. The straight shank design ensures stable clamping in standard chucks and easy interchangeability between hand drills and drill drivers. Its compact mass and durable construction reduce bit vibration and wear during use.

Suitable for

• Drilling glass, ceramics and porcelain
• Working with stoneware and brick
• Drilling soft metals such as aluminium
• Precision small-hole drilling in thin or brittle materials

Key specifications

• Material: carbon steel body with tungsten carbide cutting tip
• Cutting tip hardness: 90 HRC
• Coating: titanium nitride (TiN)
• Shank type: straight (cylindrical)
• Weight: 35 g
• Intended use speed: low revolutions, non-impact mode

How to use

Secure the AWTools AW42708 drill bit in a compatible chuck designed for straight shanks. Operate the drill at low speed in non-impact mode and apply steady, light pressure to avoid cracking brittle materials. When drilling glass, ceramics, porcelain or stoneware, use a suitable coolant or water to reduce heat build-up and flush away debris. For soft metals, maintain controlled feed rate and cooling as needed to preserve the cutting edge.

Usage recommendations

Use slow rotational speeds and non-impact drills; apply coolant or water when working with brittle or heat-sensitive materials. Inspect the cutting tip regularly and replace the bit if the carbide edge shows chipping or excessive wear.
